What is the structure of a DB2 database?
DB2 databases are a set of DB2 structures that include a collection of tables, their associated indexes, and the table spaces in which they reside.

What type of database is Db2?
Db2, or Database 2, is a set of relational database products built and offered by IBM.
Relational databases enable enterprises to create declarative data models accessible via queries.
For this purpose, IBM invented the popular and now standardized Structured Query Language (SQL)..
All data in a Db2 database is presented in tables, which are collections of rows all having the same columns.
When you create a table in Db2, you define an ordered set of columns.
Indexes.
Built upon IBM's Common SQL engine, Db2 Warehouse queries data from multiple sources—Oracle, Microsoft SQL Server, Teradata, open source, Netezza and others.
Users write a query once and data returns from multiple sources quickly and efficiently.

DB2 databases are a set of DB2 structures that include a collection of tables, their associated indexes, and the table spaces in which they reside. You define a database by using the CREATE DATABASE statement.

Data structures are elements that are required to use DB2®. You can access and use these elements to organize your data. Examples of data structures include tables, table spaces, indexes, index spaces, keys, views, and databases. The brief descriptions here show how the structures fit into an overall view of DB2.

Aspect of SQL

SQL Return Codes are used on a day-to-day basis for the diagnosis of programming failures as a result of SQL calls by IBM Db2 programs.
An important feature of IBM Db2 programs is the error processing.
The error diagnostic containing the SQL Return Code is held in the field SQLCODE within the Db2 SQLCA block.
