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.

Drop a table in a table hierarchy

If a table and its corresponding named row type have no dependencies (they are not a supertable and supertype), you can drop the table and its type. You must drop the table before you can drop the type. For general information about dropping a table, see the DROP TABLE statement in the HCL OneDB™ Guide to SQL: Syntax. For information about how to drop a named row type, see Drop named row types.
