The scope of UI Modernization data migration is to migrate legacy data from the data sources as declared in the data inventory (finalized by WYCAN and TCS Teams) to operate the new UI Modernization application.

The Wyoming State will provide data in segment flat files, loading the data from these flat files to the 'intermediate' database.

Analyzing the source data for data anomalies and understanding the source data with respect to the target table structure

Collaborating with the client to obtain data in a standardized format and with good quality

Created an ‘Extraction Issue’ spreadsheet to inform and hold the Client/ respective Teams accountable for data of poor quality

Working along with the Client on data mapping – to map the data between the Source Columns and the Target Column.

Exclusively using DB2 Connector stage, Sequential file stage, Transformer stage, Join stage, Lookup stage, Surrogate key stage, Remove duplicate stage, Funnel, Filter and some other stages for developing jobs to reflect the business rules.

Using Job Sequences to control the execution of the job flow using various activities like Job Activity, Email Notification, Sequencer, Routine activity and Exec Command Activities.

Used DataStage Director to schedule, monitor, cleanup resources and run jobs with several invocation ids for various run streams for a particular system.
