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.

Create a fragmented table

This section explains how to use SQL statements to create and manage fragmented tables. You can fragment a table at the same time that you create it, or you can fragment existing nonfragmented tables. An overview of both alternatives is given in the following sections. For the complete syntax of the SQL statements that you use to create fragmented tables, see the Informix® Guide to SQL: Syntax.

Before you create a fragmented table, you must decide on an appropriate fragmentation strategy. For information about how to formulate a fragmentation strategy, see your Informix Performance Guide.
