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.

Select a DATETIME format (GLS)

When an application displays a DATETIME value, it refers to a DATETIME format that the user specifies. The default locale specifies a U.S. English DATETIME format of the following form: 2001-10-25 18:02:13

For non-default locales, you can use the GL_DATETIME environment variable to specify the DATETIME format. For more information about how to use locales, see the HCL OneDB™ GLS User's Guide.

To customize this DATETIME format, select your locale appropriately or set the GL_DATETIME or DBTIME environment variable. For more information about these environment variables, see the HCL OneDB GLS User's Guide.
