Senior Project - Explanation

• TSD (Tivoli Service Desk) supports the use of 6 database platforms. Each of these platforms require a different set of scripts to build the database

• This project would generate platform specific scripts based on a single document

RDBMSDB/2,

DB/2 MAINFRAME, ORACLE,

SQL SERVER, INFORMIX, OR SYBASE

– Drop Tables

– Create Views

– Drop Views

– Create Triggers

– Create Indexes

Senior Project - Potential Direction

• Define the database schema in XML

• Create a Java utility to parse the XML and then generate the appropriate platform-specific database scripts

Senior Project - Student Benefits

• Database design• Enterprise scale product• Real world development life cycle process• Tools required to do large scale

collaborative development

Senior Project - Tivoli Benefits

• Eliminate a significant source of development and testing effort that recurs for each release of the product

• Defects introduced by redundant platform specific script changes would be significantly reduced
