Web Data Integration used php and mysql. From the beginning of data processing systems through the middle of the 80’s decade, integration between systems was always a custom, platform-specific affair. A continual reliance on information systems with key databases combined with an exponential growth of data. Heterogeneous Data is data from any number of sources, largely unknown and unlimited, and in many varying formats. Data integration can be defined as "the use of common field definitions and codes across different parts of an organization". Data integration is a set of processes used to extract or capture, restructure, move, and load or publish data, in either operational or analytic data stores, in either real time or in batch mode. Because of the operational and analytic nature of integrating data, the frequency and throughput of the data have developed into different types of data integration architectural patterns and technologies. Therefore, an investigation of the architectural types or “patterns” of data integration have been shown in this report. Data integration can be classified in two types direct access and data access via mediator. In this paper I tried to show different kinds of data integration where we use an example database software “USHR system” for show up the both kinds of data integration i.e direct access and mediator based data integration. Here data integrations in the database software “USHR system” is explained with flowchart and architectural diagram . Two different database is studentdb(db1) and bracias(db2) where we applied the direct access method and data integration via mediator method for integrate data individually. Then we get the resulted form “Faculty Salary Form after integrating db1 and db2” by using the direct access method and “data migrated form” for data integration via mediator method.
