Designing databasesThe first step in creating a relational database is to construct a data model, which is a precise, complete definition of the data you want to store. After you prepare your data model, you must implement it as a database and tables. To implement your data model, you first select a data type for each column and then you create a database and tables and populate the tables with data. You can also implement fragmentation strategies and control access to your data.
Designing and Implementing a DatabaseThe HCL OneDB™ Database Design and Implementation Guide provides information to help you design, implement, and manage your HCL® OneDB® databases. It includes data models that illustrate different approaches to database design and shows you how to use structured query language (SQL) to implement and manage your databases.

Automate with a command script

Your operating system probably supports automatic execution of command scripts. In most operating environments, interactive SQL tools such as DB-Access accept commands and SQL statements to execute from the command line. You can combine these two features to automate privilege maintenance.

The details depend on your operating system and the version of the interactive SQL tool that you are using. You must create a command script that performs the following functions:

Takes a user ID whose privileges are to be changed as its parameter
Prepares a file of GRANT or REVOKE statements customized to contain that user ID
Invokes the interactive SQL tool (such as DB-Access) with parameters that tell it to select the database and execute the prepared file of GRANT or REVOKE statements

In this way, you can reduce the change of the privilege class of a user to one or two commands.
