Project Overview• Developed for Chevron Information Technology

Corporation• The department deals with a huge data repository which

is of different structures distributed across different data stores.

• Integrate data from different sources and build a trusted dataset

• The application deals with the scenario in which the customer may have to access data of different structures distributed across different data stores.

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 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

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 and the user can view the data present in that table

– The primary key of the selected table would be displayed to the user

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 and the user can view the data present in that worksheet

– User will have to specify whether the first row in the file is the column header

Application Features (contd)• Select Rows:

– The user can select rows from the various data sources – Check/Uncheck open data sources for preview– Preview the selected rows– Clear the selected rows from specific table or all tables– Delete unwanted rows present in the preview– Export the finalized selection to a desired Excel file

Implementation Issues• Exporting the data to Access

– Limitation of Access does not allow an alternative

• Exporting data to an Excel file– Write the data as XML and save it to an Excel file

Project Tasks Completed by Team

• Selecting data from MS Access 2003, MS Excel 2003 and Flat File.

• Selecting multiple rows from each of the individual data sources Performing Join operation

• Clear Selection

Project Tasks Completed by Team (contd)

• Export data to an Excel sheet

• On clicking ‘Export data preview’ allow the user to check/uncheck selected tables

• Show the preview of the selected rows

• Delete unwanted rows from the preview

Future Enhancements• Support for data sources with mismatching data

structure

• Displaying visual cues for matching rows

• Performing Join operation

• Resolving conflicts of duplicate rows before exporting the resolved data

• Add paging mechanism to data grids
