These tools support migration ,to the correspondingdatabases.

Migration of data between different operating systems anddifferent databases versions, will include various troubles.

Most of the existing tools are purely plat formdependent.

User Friendly.

As the tool is developed in .NET, it is partly platformindependent.

In this tool, XML format, a platform independent format isused to represent the data globally.

NO need of buying separate tools for each of his/her migrationrequirements.

ADVANTAGES


26/31

CONTD..

The single tool considers four databases( i.e Oracle , SQL, Sybase , M.s access).

It also migrates views & procedures if supported by thecorresponding database vendors.

The tools database browser allows the user to view the tables andviews in different databases.

Minimal manual effort.
