Manage content (unstructured data) such as images, digital media, word processing documents, and Web content.īring together distributed information from heterogeneous environments. Help customers collect, prepare, manage, analyze, and extract valuable information from all data types to help them make more insightful business decisions faster. Store electronic data and enable the sharing of information across multiple platforms. Unless otherwise noted, when we use any one of these terms in this book, we are referring to DB2 running on Linux, UNIX, or Windows. In most books and documents, including this one, the terms "DB2" and "DB2 UDB" are used interchangeably. To specifically refer to database servers, " UDB" needs to be added to the name, as in DB2 UDB. Table 1.1 shows the DB2 Information Management portfolio and the product offerings under each classification. Today, DB2 represents a portfolio of information management products. All versions of DB2 on distributed platforms and on MVS, AS/400, VM, and VSE have adopted the name DB2 UDB. IBM included the term "Universal" in the name to represent the new capabilities of this version. Moreover, this universal database was able to run on a variety of hardware, from uniprocessor systems and symmetric multiprocessor ( SMP) systems to massively parallel processing ( MPP) systems and clusters of SMP systems. It was the first version optimized for the Web, and it supported a range of distributed platforms-for example, OS/2, Windows, AIX, HP-UX, and Solaris-from multiple vendors. With this version, DB2 was able to store all kinds of electronic data, including traditional relational data, as well as audio, video, and text documents. In 1996, IBM announced DB2 UDB Version 5 for distributed platforms.
DB2 development continued on mainframe platforms as well as on distributed platforms.įigure 1.1 shows some of the highlights of DB2 history. "DB2" was used to indicate a shift from hierarchical databases-like the Information Management System ( IMS) popular at the time-to the new relational databases. Development started on mainframe platforms such as Virtual Machine ( VM), Virtual Storage Extended ( VSE), and Multiple Virtual Storage ( MVS). Since the 1970s, when IBM Research invented the Relational Model and the Structured Query Language ( SQL), IBM has developed a complete family of RDBMS software.
