|Project Description: ||With the rapid explosion of databases in the field of computer science, the need has come to merge data from several heterogeneous sources. This project implements the data integration of Ocean Observatory Systems along the Gulf of Mexico. The implemented system will give unified view of ocean data to the user. The data retrieval is done from several ocean observatory stations using the Web services they provide. There are various tools and procedures by which data integration can be accomplished. One of the ways of retrieving and integrating the data can be done by using a HTML parser via HTTP. Similarly, there are other ways which have many disadvantages. The data retrieval and integration is much simpler and advantageous using the Web services. This project uses Sensor Observation Service, which is a Web service that provides an API for managing deployed sensors and retrieving ocean data from the sensors. This project retrieves and integrates data from four different ocean observatory systems using web services.
