All database definitions should be reviewed by Data Management before being used to define test or production objects. Production turnover of database objects is done by Applications. Data Management provides whatever assistance necessary to complete the turnover. It is the responsibility of Applications to involve Data Management at different stages and walkthrus of the application development life cycle. Applications are alerted of any situations which need to be resolved with their involvement.
Applications are the first line of support for application specific database problems.
Data Management assists Applications in revolving these problems whenever necessary. The Data Management, MVS Systems, and Distributed Platforms teams are responsible for resolving database system level problems.
