Operating System/400 (5722-SS1)
• ANSI X3.135.1999, ISO 9075-1999, and FIPS 127-2 Structured Query Language
(SQL)
• IBM's Distributed Relational Database Architecture (DRDA) Distributed Unit of Work -
Application Directed
• Microsoft's Open Database Connection (ODBC)
• Apple's Data Access Language (DAL)
X/Open's Call Level Interface (CLI) Supported transmission protocols for the iSeries include:
• Transmission Control Protocol/Internet Protocol (TCP/IP)
• Advanced Program-to-Program Communication (APPC)
DB2/400 database has been integrated into the operating
system since its conception. DB2/400 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 DB
is integrated allows the operating system to control some of its
management functions and makes it easier to maintain than
competitive DB from other vendors reducing the need for a
dedicated Database Administrator. Integrated into the operating
system are its security functions, which allows a better security
model than other DB where additional tools may need to be purchased to provide these
functions.
The SQL Client Integration API allows providers of gateways and client/server solutions to
integrate their products with DB2 UDB for iSeries. 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.
It includes all the support necessary for new and existing database applications to run on the
iSeries server. Application development facilities are provided in the optional DB2 Query
Manager and SQL Development Kit for iSeries, the next evolution of the SQL/400 product.
This product includes Query Manager, an interactive panels and query builder for
user-developed report generation, and Interactive SQL, a prompted interface for running and
testing SQL queries. For the application developer, the SQL Development Kit provides SQL
precompilers and tools to assist in developing custom SQL applications in languages such as
C, Java, RPG, COBOL and REXX. Once created, the applications and queries can be run on
any iSeries server.
Support is provided for embedded static, dynamic, and extended dynamic SQL, together with
the IBM Distributed Relational Database Architecture (DRDA), Microsoft Open Database
Connection (ODBC), and Apple Data Access Language (DAL). A Call Level Interface (CLI)
