| With the increased shift towards GeoSpatial Web Services on both the Web and mobile platforms  especially in the usercentric services, there is a need to improve the query response time. The  traditional routing algorithm requires server to process the query and send the results to a client but  here we are focussing on query processing within the client itself. This paper attempts to evaluate  the performance of an existing NoSQL database and SQL database with respect to routing  algorithm and evaluate whether or not we can deploy the computations on the client system only.  While SQL databases face the challenges of scalability and agility and are unable to take the  The advantage of the abundant memory and processing power available these days, NoSQL databases  are able to use some of these features to their advantage. The nonrelational databases are more  suited for handling the dynamic rise in the data storage and the increased frequency of data  accessibility.  For this comparative study, MongoDB is the NoSQL engine while the PostgreSQL is the chosen  SQL engine. The dataset is a synthetic dataset of road network with several nodes and we find the  The distance between source and destination using various algorithms. As a part of paper  The implementation we are planning on using pgRouting for the analysis which currently uses  PostgreSQL at the backend and implements almost all the routing algorithms essential in practical  scenarios. We have currently analyzed the performance of NoSQL databases for various spatial  queries and have extended that work to routing.  Initial results suggest that MongoDB performs faster by an average factor of 15x which increases  exponentially as the path length and network data size increases in both indexed and nonindexed  operations. This implies that nonrelational databases are more suited to the multiuser query  systems and has the potential to be implemented in servers with limited computational power.  Further studies are required to identify its appropriateness and incorporate a range of spatial  algorithms within nonrelational databases. |
