A nalyzer Tool for Infosys Technologies L td. The Meta Data Impact

A nalyzer is a tool developed to face the challenges of Metadata

management and to enhance the quality of Metadata management

p rocesses. The Meta Data Impact Analyzer can connect to a database or

an ETL tool and retrieve the tables and fields. The tool can add, modify

and delete fields and study the impact of the mentioned operations on

t he fields. The tool summarizes the impact and displays it for the user

for assessment. The fields added to study impact can also be saved and

can be opened later to work further. The impact can be fixed later to

establish the impact. The tool provides an easy to use user interface for

t he operations. The tool eliminates the manual analysis of the metadata

and makes changes without user intervention.
