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.
Basics of database design and implementation
Implement a relational data model
Create the database
Use CREATE TABLE
Drop or modify a table

Drop or modify a table

Use the DROP TABLE statement to remove a table with its associated indexes and data. To change the definition of a table, for example, by adding a check constraint, use the ALTER TABLE statement. Use the TRUNCATE statement to remove all rows from a table and all corresponding index data while preserving the definition of the table. For information about these statements, see HCL OneDB™ Guide to SQL: Syntax.
