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
Build a relational data model
Identify and define principal data objects
Discover entities

Discover entities

An entity is a principal data object that is of significant interest to the user. It is usually a person, place, thing, or event to be recorded in the database. If the data model were a language, entities would be nouns. The demonstration database provided with your software contains the following entities:

customer
orders
items
stock
catalog
cust_calls
call_type
manufact
