DB2 is a relative model database server from IBM. DB2 has 3 main products . DB2 for Linux, Unix, and Windows (LUW), and DB2 for iSeries (earlier OS/400). The DB2 LUW product runs on numerous Linux and UNIX distributions as red hat linux, suse linux, AIX, HP/UX, and Solaris, and most Windows systems. DB2 also powers the IBM InfoSphere Warehouse edition, which is typically DB2 LUW with Database Partitioning Feature (DPF) a massive parallel data warehousing architecture. Another RDBMS, Informix, was attained by IBM
Firstly, IBM had developed DB2 product for their specific platform. From Since year 1990, it decided to develop a Universal Database (UDB) DB2 Server, which can run on any authoritative operating systems such as Linux, UNIX, and Windows.
It provides solid industry leading performance, high availability and mission critical assistance, reliability of the platform, handling high value workloads, robust, optimize performance, and reduces both total cost of ownership and operational cost. It can easily be used on the location, in private or public environments which includes a range of management and application development tools. It can advance to a multi user system from single user application. And also it delivers simultaneous user access from DB2 and other databases using SQL.
Database 2 or DB2, introduced by IBM is a Relational database with several advantages that favour storage and manipulation of data. Data can be accessed and understood very easily, concurrency is high and so is security. Evanta Technologies brings you complete and interactive online course called IBM DB2 Online Training that will introduce you to the fundamentals of DB2. You will learn how to download, install, and use DB2 and its tools. After the end of this course you will be well versed with database management concepts.
The DB2 provides a firewall so the application runs in a dissimilar address space than the DB2 database server. The firewall will defend the database and the database manager from applications, stored procedures, and user-defined functions. The firewall upholds the reliability of the data in the databases, as it prevents application programming errors from overwriting database manager files. The firewall also improves the reliability, because application errors cannot crash the database manager.
DB2 support multiple instances in a single system. Supports Import, Export, Load and DB2 move utilities to integrate data.
IBM DB2 is one of the powerful RDBMS software that help to achieve huge voluminous (128 TB) data and put up special CLOB, BLOB data types. DB2 is well-suited with various operating systems and federates with different types of databases. DB2 is one of the leading Web-based databases.
