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.

DataBlade data types

The diagram in Extended data types includes DataBlade® data types. A DataBlade is a suite of user-defined data types and user-defined routines that provides tools for a specialized application. For example, different DataBlade data types provide tools for managing images, video, and geographical information. Such applications often require opaque data types and other user-defined data types. For information about developing a DataBlade module, see the HCL OneDB™ DataBlade API Programmer's Guide.For information about the DataBlade modules that HCL provides, contact your customer representative.
