iSeries architecture: Fundamental strength of the IBM ^ i5 and iSeries 35
Draft Document for Review October 18, 2004 5486AdvTech.fm
DB2 Universal Database
DB2 Universal Database (UDB) for iSeries offers state-of-the-art database
functions and open systems, and standards-based technology. It also provides
the maturity, stability, and ease of use that has become the trademark of the
iSeries server. DB2 UDB for iSeries is fully integrated into the i5/OS operating
system software. It is not a separate product.
DB2 has been enhanced over the years to include many new and emerging
standards. The integrated database is a full function database with features
competitive to other widely used databases. The fact that the database is
integrated allows the operating system to control some of its management
functions and makes it easier to maintain than competitive database from other
vendors reducing the need for a dedicated Database Administrator. Its security
functions are integrated into the operating system. These functions allow a better
security model than other databases where additional tools may need to be
purchased to provide these functions.
Many iSeries customers have the need for applications that not only access DB2
UDB for iSeries data, but also access data on other databases platforms such as
Oracle or Sybase. The SQL Client Integration application programming interface
(API) allows providers of gateways and client/server solutions to integrate their
products with DB2 UDB for iSeries.
See “DB2 Universal Database for iSeries” on page 521 for further information
about i5/OS for DB2 UDB, and Chapter 26, “IBM licensed programs: Database
accessories” on page 609, for associated database products.
Java and e-business for iSeries
Java is the environment of choice for programming in today's network computing
environment. It allows true portability of applications between platforms without
modification or recompiling. The iSeries servers are uniquely positioned to
leverage Java as it evolves from its current Web focus to a full commercial
application environment. The strengths of the iSeries server are combined with
Java's object-oriented, network computing technology to provide solutions in this
millennium.
See “IBM Java for iSeries” on page 511 for more information.
