Editions
DB2 for Linux, Unix and Windows has three separate editions: IBM DB2 Express-C, Workgroup Server Edition, and Enterprise Server Edition. Each of these editions has different groups of features for different sized workloads. Applications built for lower editions of DB2 are guaranteed to work on higher editions but at a higher level of performance.
The no-charge version of DB2 is called DB2 Express-C. DB2 Express-C is in some ways similar to the open source databases such as MySQL and PostgreSQL as it is offered unsupported, free of charge for unrestricted use including use in production environments. Users needing enterprise level support and fixpacks must buy any standard DB2 Edition. DB2 Express-C, however, is based on the same code as other DB2 for Linux, Unix and Windows editions and is not open source. DB2 Express-C is also similar to the free versions of Oracle database and Microsoft SQL Server, except that DB2 Express-C has no limit on number of users or on database size. DB2 Express-C runs on 32 and 64bit Windows, Linux on x86, x64 and POWER processors, Solaris on x64 CPU and Intel machines running Mac OS X. It can be installed on machines of any size, but the database engine will use only two CPU cores and 2GB of RAM. Support is provided on a free, public Web forum. For this edition there are no fixpacks or official support from IBM.
DB2 for z/OS (the mainframe) is available in its traditional product packaging, or in the Value Unit Edition, which allows customers to instead pay a one-time charge.
DB2 for i (the former DB2/400) is the third major incarnation of DB2. It is very closely incorporated into the operating system of the IBM System i machines.
DB2 also powers IBM InfoSphere Warehouse, which offers data warehouse capabilities. InfoSphere Warehouse offers several different editions and is available for z/OS, Linux, Unix, and Windows platforms. It includes several BI features such as ETL, data mining, OLAP acceleration, and in-line analytics.

Famous quotes containing the word editions:
“The next Augustan age will dawn on the other side of the Atlantic. There will, perhaps, be a Thucydides at Boston, a Xenophon at New York, and, in time, a Virgil at Mexico, and a Newton at Peru. At last, some curious traveller from Lima will visit England and give a description of the ruins of St Paul’s, like the editions of Balbec and Palmyra.”
—Horace Walpole (1717–1797)
