According to IBM, DB Express-C database is also a commercial product of the company, but it must run within the company's limited hardware range. This free version of the database can run Windows or inux operating systems, and can be configured on 32-bit or 64-bit systems with two processor cores, it can also be used on AMD and Intel Dual-core chip servers. It limits the memory to 4 GB, but does not limit the size of the database and the number of users.
IBM said it decided to add free database versions to its product lineup as its biggest business competitor Oracle and Microsoft took similar actions. Later last year, Microsoft launched the SQL Server 2005 free version, and Oracle released the free 10 GB version.
In order to attract more software developers, the three enterprise database providers helped to influence the company's technical decision. In addition, open-source databases usually include free versions. these free versions have been widely used in enterprises around the world over the past few years. According to the latest survey by Evans Data, a developer Research Institute, 70% of developers last year installed and used free open source databases. Open source database MySQL is the most popular database for software developers.
According to IBM, the database code of the DB2 Express-C version is Vipe, which will include the hybrid relationship and XML database functions. it is expected that Vipe database will be released this year.
