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.

BLOB data type

BLOB data type

You can use a BLOB data type to store any data that a program can generate: graphic images, satellite images, video clips, audio clips, or formatted documents saved by any word processor or spreadsheet. The database server permits any kind of data of any length in a BLOB column.

Like CLOB objects, BLOB objects are stored in whole disk pages in separate disk areas from normal row data.

The advantage of the BLOB data type, as opposed to CLOB, is that it accepts any data. Otherwise, the advantages and disadvantages of the BLOB data type are the same as for the CLOB data type.
