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.

Table fragmentation strategies
What is fragmentation?
Fragmentation and logging

Fragmentation and logging

Fragmented tables can belong to either a logging database or a nonlogging database. As with nonfragmented tables, if a fragmented table is part of a nonlogging database, a potential for data inconsistencies arises if a failure occurs.
