5. Overview Data Integration & Resolution Component Application is a new, self-contained product. It deals with the scenario in which the user is required to work with data distributed across different data sources. The application enables the user to view, compare, integrate data and build a trusted resultant dataset.

6. End User The various users of the system have similar data stored in different databases The user of the system would obtain data from other users and would want to visually compare them with the help of cues provided by the application The user would then be able to build a trusted and resolved version

7. Application Features The user will select the data source and will be prompted to provide the parameters depending on the type of data source selected For flat files, Excel sheets and Access database, user will specify the location of the data source file For other data sources like Oracle, SQL Server, user would specify a DSN

8. Application Features (contd) • For flat files : • User has to specify the delimiter used in the file • By default data in a single line (i.e. separated by a new line) is considered to be a new row • User will have to specify whether the first row in the file is the column header

9. Application Features (contd) • For access database : • All the tables in the selected database file will be displayed and the user can select one data table at a time as the data source • The primary key of the selected table would be recommended to the user • The user can either use the recommended key or user can select other fields as primary key

10. Application Feature (contd) • For excel file : • All the worksheets in the excel file are displayed and the user can select one of the worksheets as the data source • User will have to specify whether the first row in the file is the column header • By default the first column of the worksheet is considered to be the primary key

11. Application Features (contd) • Handling of data types • Default data type for data elements is considered of type string • Special characters in the data elements will be handled accordingly • The application integrates data of single, flat tables

12. Application Features (contd) The GUI uses color and visual cues to identify matching rows The user selects the specific records from the various data sources and can view the ‘resolved’ table The user can then export this single ‘resolved’ table to an Excel Sheet Users can hide/reveal columns by clicking on them.
