Quick Beginnings for DB2 Extended Enterprise Edition for UNIX


Chapter 1. About DB2 Universal Database

DB2 is a relational database management system that is web-enabled with Java support; scalable from single processors to clusters of symmetric multiprocessors; and multimedia capable with image, audio, video, and text support.

The DB2 products and components that are provided on your CD-ROM include DB2 Extended Enterprise Edition and the DB2 Client Application Enabler. These are the features of each product:

DB2 Universal Database Extended Enterprise Edition
Provides the ability for a database to be partitioned across multiple independent machines of a common platform. To the end-user and application developer, it still appears as a single database on a single machine. This fully scalable database system enables an application to use a database that is simply too large for a single machine to handle efficiently. SQL operations and utilities can operate in parallel on the individual database partitions, thereby speeding up the execution time of a single query or command. This product also includes the DB2 Connect feature that allows access to databases on AS/400, MVS/ESA, OS/390, VM, or VSE systems. DB2 Extended Enterprise Edition was formerly known as DB2 Parallel Edition. The DB2 Client Application Enabler component is provided on the CD-ROM. It provides the ability for a client workstation to access a DB2 server.
Note:DB2 Universal Database Extended Enterprise Edition is commonly referred to as DB2 server or DB2 Universal Database throughout this book.
