Two-Tier Architecture for Web Mapping with NoSQL Database CouchDB

Two of the greatest challenges of mobile data collecting applications are replication and synchronicity. This paper deals with these challenges and offers a new solution: two-tier architecture using CouchDB. CouchDB is a RESTful non-relational (NoSQL) document-oriented database with the ability to serve web pages directly from the database. CouchDB is acting as a web server and data storage on the server side and as a web browser on a client side. Although cloud functions on a mobile device can be used, the main advantage of CouchDB is the ability to work offline with both data and application, replicating the results back to the server. Combining such a solution with GPS we get simple mobile GIS data collector in a standard browser application. Many smartphones and mobile devices can be transformed to mobile data collectors with ease. In this paper, we will show the fundamental CouchDB concepts as a data and application storage.
