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 Informix® Database Design and Implementation Guide provides information to help you design, implement, and manage your Informix® 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.

Capture the schema

The dbschema utility is a program that examines the contents of a database and generates all the SQL statements you require to re-create it. You can build the first version of your database, making changes until it is exactly as you want it. Then you can use dbschema to generate the SQL statements necessary to duplicate it. For information about the dbschema utility, see the Informix® Migration Guide.
