so thanks for coming everybody this is posters for managers and foster the does that repre technical conference so ratio of nerds the suits is very high so after those really originally attempted to title this talk was just for managers I and actually carry self-identify here's self-identify as a manager so what are the rest of the people doing here the the others are there the result of this that the managers by proxy you know get the arguments to bring home others is not open source matters posters for managers for a specific but as a fairly so there's a real constituency for this kind of topic this kind of talk I think about this is makers you're considering getting their feet wet with open source who have started down the road but maybe there is still uncertain about experimenting with something is mission critical as the enterprise databases so solar you in a quick dirty secret at least 1 of my points will involve recommending engaging either the company I worked for or 1 very much like like like it so I've decided that in order to avoid any appearance of conflict of interest and then proceed all my blatantly self-serving advice when the location of
the head node to move them all glory to the motor so that is our invoke the vocoder I might as well go and do my self-serving biographical
details and so this was born on the on the posttest Project cofounder of posters Steering Committee chair and opposes developer so at the features that I through the my features things like geography point clouds that were linear referencing work so secluded CERCLA geometry Herbie geometry that's the stuff I worked on primarily and that I'm hole here a week so feel free to ask any questions but posters
and so the audience here for a posters for managers what kind of folks are you how many of you would describe a sales matters is only a few I what kind the questions are important managers probably not language implementation or sequel analysis tricks for library dependencies more more practical things flight from organizational strategy point of view of what is this thing and get do what I need in general terms who else is using it and assuming I go forward with this what's the plan was a plan of action so this style what is this
thing hysterical and I put it but you talk about Randy what is this post thing anyhow
and this is the grades right big cylinder right it's the place you start your data I 1 understand the cylinder is also the answers questions about your data like what in this polygon help assistance store but graphs is better to reason by analogy I'm as
Oracle is the post rescue well Oracle
Spatial is woops Oracle Spatial is the posters a spatial database is just a database that hot but with some extra goodness added for dealing with spatial data
inquiry so posters takes plain post well in adds types flood geometry geography of functions like area union a buffered indexes like trees and you hashes once you have these entries in a database these types functions indexes your database becomes less ordinary continue and wonderful things like to GIS queries the database so generate a list of neighbors notify calculate the average drive the truck summarize partial areas by the zoning you name it you can do these GIS things unlike GIS files databases are built to maintain its integrity under work right load from multiple sources so no passing files around more integration with other real-time systems and also unlike files databases expect to be asked to handle large databases large volumes of data and large workload to the plot and
really all the author things about posters are also there are some things about other spatial databases to they all you had suggest questions they all break away from tyranny of files and file oriented tools they handle big datasets efficiently but is post just in the same league as those other databases as the sequel server oracles of the
world and so is technology let's talk about rock capability let's get on our get our gurdy so rather just talk what posters can do which is a lot of people can find a more convincing when I put it next to the leading commercial brand which is the space of Oracle so here's a quick introduced for this possible but thorough feature comparison so
both databases support basic John types defined by the UGC both support box is defined by ISO Oracle support some fancy kinds a box of cat books used were they both have similar support for storing retrieving 3 volumes and you can see more posters top being given later on in this week on friday Olivia Cortes about Jessica's treaty I build databases store geometries with more than 2 dimensions together z-dimension on a measure or dimension and both index geometries over all 4 dimensions portal has a quirky annotationType which is again for GIS or sorry for CAD program support bowl databases handle geodetic coordinates of latitude longitude Midgley bowl implementation details of slightly different people have indexes and functions that support you that accorded streams when my courses the both of them support accord assistance re-projection in the database the article the spatial indexing of posters has an extra text index types that extra to the only index for higher performance and posters can do multi-key indexes which is important for more complex queries they both have a large collection of functions that often interfacial data oracle functions of control tolerance model which is nice and posters finer detail on spatial relationships and some really handy arrayed aggregation support the Oracle doesn't have an a general POS justice has more functions than oracle and both support nearest neighbor searches although oracles that more complete have opposed is is better utility functions ran jungian installation and they don't have a big collection of features that are related to or built on top of often used with the coarse spatial PhoNet functionality things like topology point clouds Rasta support geocoding around it so both databases can do an awful lot and when you add it all up the bit where oracle does a little bit more and for posters does a little bit more I can that included the functionally they really are all that different
they much the same functionality but for some small differences so from a technical point of you get the big on posters can be what you need so move on to the next managerial question who else is using PostGIS then
it's ordinary human cheap nature to feel more comfortable with the decision is validated by other folks so let's look at other organizations they're using
posters so 1st of all states actually I don't know that posters at all values like included as examples of it organization using posters he'll at scale at the left post breast scales the data back in the 1st guy is pos crystal every call log all the billing is tracked using post another example of a really big POS fresco installation at scale Instagram 100 million concurrent users all running unopposed SQL faster so you can scale post-critical up to arbitrary absurd limits on C will never get there but it can be done so sizes and something you need to worry about it does scale
Google DigitalGlobe both big organizations using posters the user for similar purposes actually are they used to manage the collection of images and don't put the images themselves database but they put the image metadata in the database which allows them to control their Image Proc preparation automation to figure out what the best image for any particular mosaic is to find historical data behind a particular pixel and so on when people
ask me what the biggest single-dataset being stored posters is usually site I UK Ordnance Survey the master map database that's over 5 million records and size the probably larger space is that's now things like letter collections and so on but the as a genuine classic GIS dataset master map is a pretty good example and it's really not people have half billion feature J. has datasets but this is 1 order survey uses posters on the Web 2 years so it supports light mass rendering us deploy damage on Amazon Web Services on not they use it but number the customers that provide services using their data also use it so posters as a host for master map is a pretty common thing to see in the UK now the
FAA fun example they move all the airport management data and they're noticed aviators books all protraction of those books to a posters but which school but the really things they were so happy with the results of doing that the results were so good in terms of flexibility in terms of in terms of price to customization they set up a part a policy that all the future systems that they build within the FAA are also can move away from Oracle to post rescue well so as things as system's age out the we replace it with new systems based on PostgreSQL and oracle
and they evolve in a big organizational examples right but even smaller organizations so for sample Pierce County Washington state converted enjoyed good results they convert from sequel server the posters and they maintain a hybrid architecture like was talked with earlier in the session using our GIS desktop traditional GIS management analysis but with posters to serve automated analysis of database and then publishing out to the web the as already
mentioned UK Ordnance Survey but national mapping agencies in general have moved posters in a big way to start with the Web publishing space of Ezra happened silent you look at Open Source Adoption in the tensor start the edges start with the Web publishing workloads and build your 1st web map maybe start taking or operational database and replicating posters publishing out of that but then working their way and taking over existing workflows until finally the the the last step is becomes the obvious 1 why don't we change our enterprise databases supposed and some of the national mapping agencies of gone through the entire cycle starting at the idea of working their way in and actually have gone to become a pure posters posters operations are easy and uh there's little bit they were the national mapping agency to adopt posters further beauty needed a set and they pretty much gone all of this point the the so
how do we change what's the plan the change for proprietary to open source and 1 way to take off is new the whole thing from water the but it might be emotionally satisfying plan for some of us he is the only way to be sure that but is not realistic but organization cannot cut overall IT systems 1 1 day the day-to-day operations have to go on and most the staff time in organization is just can be devoted to keeping the wheels turning keeping the day-to-day organization running you can really only devote a fraction of your staff to trading systems of tomorrow so what's the plan was the solution to get from here to there and 1 thing we account for with right
away said during the transition period there's going to be 2 databases run and the situation can easily go on for number of years it's not permanent but it's not entirely temporary either it's it's a phase and standing up
a working pose crystal posters database fertilization is a good 1st step gives you that existence proof of the thing actually runs the frontier idea here Joe turn it on and works on it gives you a place to see how well your existing tools can work with that there's lots of 3rd party tools that were supposed to supposed SQL I'm I can tell you that we really don't know until you try it others nothing better than try it and see how it works I give your staff a chance to actually get hands-on and experience again need as you start to migrate bigger more complex applications I give you a chance to test migrations of applications and finally when you go from the learning experimenting phase actually starting trend is the transition it will become 1 of your production databases 1st all have 1 half that will to little of 5 so how to go
about turning your Oracle people into Postgres people that the might see like visual mission impossible right you know the Oracle guys been doing all his life and does it will look at new stuff actually true I last
year I got to go to the post open conference in Chicago it is the year before the 1 they noticed was all the folks don't of folks and that the from State Farm Insurance as the former churches headquartered Bloomington Bloomington Illinois is came up the highway I the reason why there is this a the delegation like a dozen people stay fire was it they are migrating from Oracle oppose rescue of so the migration team who were all oracles specialist they're only be is in the Senate outpost press open to learn new things and that's the stuff upgrading you can do stuff in that way it doesn't take a lot of because most staff recognize that learning new skills increases the value I've been most staff if the good technical stuff find learning new technical stuff interesting our own if you have started all at anything system but the problem is not the new things I and really the transition the transition oracle the pose with the transition from 1 database to another doesn't require much learning has deviates they already know both the core concepts all you really need to live learn our certain new terminology new ways of labeling things and some details about how things are done they understand the core problems there already deviates that done the hard the of that workstream
examples that you the staff are augmentation it doesn't apply to most organizations of but example I played out without a sales force the com which is oracle shop so they say always suffers a service don't care what's underneath Lebanese oracle and and when they see the really out of the blue they are they hired Tom lean was 1 of the top was rescued L
developers it turns out they were to up to migrate their core infrastructure post rescue well and so their thought was a service business they've got mission critical reliance on the core database right this is it so having the number 1 expert in their employ it was a big risk producer as a making this transition other turns out sales force didn't end up migrating the use the threat of migration to dramatically improve the licensing deal oracle I but with the same period that it actually the purchase roku is another platform that's officers were platform users company in program has a big reliance on posed as they kept on other probably helps them to future proof that you oracle to tell teacher Thomas mulling by the way you read but later rejected by catalog of the stupid teacher In short minus 1 for me regards public so staff
transitions it should really be a problem for the DBA is the road a slew the core skills are the same in many ways post rescue is a much easier beast manage that oracle and for the analyst to developers moving more work flow into the database gives them access to the power sequel and and the skills readily acquired with a few days course work that give the analysts a new power tool it gives a developers access to spatial functionally which previously they would work required the overhead of learning a new just all like GIS systems the so the
how to make a plan how do you go about world using the elephant right know that take very small bites and a lot of them so stand up a parallel server migrate some applications upgrade your staff skills it exercise them all on migration keep on moving once you get a better momentum make shutting down the legacy server the new rules so the 1st crises and stuff working but eventually get to the point where the goal of the giver the old stuff and actually just about this but from example Denmark service in small things and then move forward to to actually the goal is turning down the old stuff but don't about
support all glory to denote
a of thought you'd never ask and so good news is actually companies that
exist to rely on all the things they're usually provided by proprietary vendors and you know the support functions testing integration building up source code from source to binary so it's easy to install and use training services to upgrade your staff of professional services for complex stuff that you might not have the skills to do and companies that provide the Asher and that the software will be professionally maintained in the future and built for user customer and the insurance that if things do go wrong they'll be someone you can call the help and coincidently having to work for those
companies balance provide support subscriptions for OpenGeo Suite which is a full stack of technology for web mapping including just and USA and open letters that were hardly unique there's lots of copies of feel that had a role of so called Cloudera fills that role over Hadoop Red Hat fulfill that for Linux Enterprise DB fulfill that for a plane Bilbo's graphs so we've covered all managerial questions about posters and what is the sense it's
a spatial database let you store query spatial data just like any other data using sequel Sykora language i'm gonna do it I did yet they
do basically the Oracle Spatial can do so if you need any more than that you're already world anyway and that is using it just you know
tiny people academics students know lots of big series organizations both public and private are using posters for real world war so
convinced hiking together with the plan getting organization at the post is is not a big left get you develop environment up give your Stassen training and use of learning time right is not just about the class you learn just you know here's a Datalog yourself try this test problems and then migrate your applications a little bit of time to learn and grow your skills because what is the alternative right the alternative to getting a
poster that if you don't go you run afoul of the 1st law of holes which is if you find yourself in a hole the 1st thing to do is to stop digging the so thank you very much has been posted for managers do you have any
questions but and the for instance in but is it on the effect of you mentioned heroic who armed In the context of posters here and we looked at it about 4 months ago they had just started on Mrs. path so we ended up using an AWS posters insulation and with the workers servers how any word on how that's going in the stability there in is set looking like a good option for small offices start this year of Enterprise or a couple months I've been talking Rocha guides for a couple years cost is the thing that they have kept their posters on their for-pay tiers so if you wanted to run their free tier you couldn't get the post is part and so if you really to pay money you can get process if you wanna pay less money you can go now without was on RDS with a really small RTS image which probably cost you less and when you're new development phase use a bigger 1 when you get a production that the I have a question as the composition wrote or and post use equal yes up oracle has earned P a musical support posted a language sickle does produce a comparison of support yeah apples growth has a procedural language it's cold and probably on purpose so the article is called the else less equal of those resources called PL slash PGs equal and they're syntactically very similar although not identical but but if you have pills equal skills they should translate into POP pigeons well pretty well you can also run all sorts of other procedural languages if you're crazy so you can run appeal by thought appeal Pearl ICA PL R&D statistics right the database you unpeel JavaScript's I think it's called kill the 8th use the Jouse be engine and pretty much any language that you want to write procedural code in post Christian have appeal option but PLP T-SQL QL is the oldest in the traditional 1 following the soon question I asked earlier the moltaí editor the versioning and replication so the In the context of the previous talk of the example given was 1 word organization was previously using files but had a copy of arcadia service sitting on the shelf I'm collecting dust stood up a PostgreSQL PostGIS database input RJ a server on top of it and kept on editing with the existing workflow and that 1 of you the versioning is there and not just have to do it over is provided by gesture using as risky the if you're doing something at different let's say or just of editing is with futures there are some computers plug-ins that provide on have a similar version idea to to the ones that you provides if here other than that you start getting into interesting sort of had rolled a a self-ruled solutions a my the result for ones refer history not versioning which are very easy to just do with database triggers not for actual multiuser check versioning and the probably the the shortest path ahead is that's does that is by grounding these off-the-shelf right now would be to use a g again impose stressed and the editing tool of your choice to edit your check that data and use the due process to actually manage the merging of external branches into a central database thanks our same question Asker earlier to and you mentioned curry stuff here that I can use some people your mail at the CAD tools I downloaded so can take care tools to occurs lines splines and circles and great stuff and it will store I'm using cages input yes no and yes but mostly no so for on CAD tools like AutoCAD have lots of kinds of curves and the ISO specification that post is used to I only specify circular arcs 3 simple kinds of curvature I and really get support for that kind of geometry up and down your whole stack at every level the stack has to understand so sure posters understand that I but of other cages understands curves natively see some of the indicators experts as key just do direct current editing have occurred object no no no and so a lot of a lot of tools that you have to you curves stroke them into linearized linearizations and rather upon the strain we don't have direct editing of so you have all the parts posters has the hardest but to do it practically need every level the stack but but what issues I have trained it has moved over to the post closer servers our organization is the DBA is of really don't like the administrative tools PG admin and stuff like that compared to the ones used to work with Microsoft any ideas suggestions on that like actually utilities exhibits defined as pretty as some of the other ones yeah I I don't there are some of proprietary interviewees front ends for administering post post press which make it a little less painful I I think the transition is easier for Oracle DB is because they're used to being abused and the sequel server the visitors gone soft you know it's always a you if I say I don't know Siegel's there is a high bar in terms of providing these really user-friendly affordances and I don't know any any tools and really get that water level of the post side but is worse poking around some of proprietary from is that you provide sometimes nature you eat your folks the but the more questions that for the recommend some monster certification for posters or 2 to the creation the we certification courses balance producer will eventually have ones for posters on I feel like Enterprise DB does have certification courses for a generic post stress I and those who appointed you say I'm an effective DBA it's well worth getting those because those tend to be really focused on DBA tasks and the place where posters PostgreSQL deviates from plain poster has post best relative the things you might learn is around the sequel and the developers left analysts roles because the right such different queries In the spatial world and you right in the play natural world the actual administration those databases is exactly the same so if you learn how to administer stress from the pricey CB you've learned enough to administer posed as posters database well the draw and thank you for coming Thank you there's a you

Abstract Your staff keep talking about this "PostGIS" thing, but what is it? Does anyone (important) else use it? What for?This talk gives a brief overview of the place of PostGIS in spatial IT architecture, how PostGIS compares to proprietary alternatives, who is using PostGIS, and how organizations transition to open source databases.
