The Data Manager is intended to provide assistance as part of an overall process for initial database creation. At a high level, that process includes the following three main steps:
The aim of the Data Manager is to help establish a skeletal database. Subsequently a DBA can then write handcrafted scripts to complete the database by modifying tables and settings such as LOCKSIZE or BUFFERPOOL.
A DBA would not be expected to manipulate the Cúram model to define extra entity options such as LOCKSIZE, BUFFERPOOL, and so on, in order for the desired SQL to be generated. This is due to a number of factors. The modeling tooling is designed to be unaware of the final deployment environment, and DBAs would not be expected to have the skill-sets for using the modeling environment.
The Data Manager is not intended to be used to upgrade an existing database; it exists simply to reset the database to a known state.
