DB2 is a family of database server products developed by IBM that support relational and object relational models. DB2 was first introduced by IBM in 1983 for mainframe systems and has since been ported to Linux, Unix, and Windows. There are three main DB2 products: DB2 for Linux, Unix, and Windows (DB2 LUW), DB2 for Z/OS (mainframe), and DB2 for iSeries. DB2 LUW provides features such as high availability, security, workload management, and federation between data sources. The document discusses DB2 architecture including the instance model, database storage model, engine dispatchable units, and memory architecture.

3. What is IBM DB2?
DB2 is a family of database server products developed by IBM
INTRODUCTION
These products support relational model, object relational model, non-relational models
Little history:
Introduced by IBM in 1983 to run on its MVS (Multiple Virtual storage) mainframe platform
Later ported on open systems (Linux, Unix, and Windows)
Right now DB2 offers Industry leading performance, scale, and reliability on various platforms
Today, there are 3 main products in the DB2 family.
•DB2 for Linux, Unix, and Windows (a.k.a DB2 LUW)
•DB2 for Z/OS (Mainframe)
•DB2 for iSeries (formerly known as OS/400)

5. DB2 LUW product features
 High Availability
 pureScale
 pureXML
 Security
 SQL compatibility
 Storage optimization
 Time Travel Query
 and much more …
 Work load management
 Federation between data sources

7. In a DB2 instance, we can have more than one database
Each database is a combination of many both logical and physical structures
