SAP MaxDB software installations consist of shared software on the one hand and dependent software on the other hand.

Shared software is the software commonly used by all installed SAP MaxDB databases. It is stored once on the database computer and automatically updated with any installation of a different software version:

If you install a version higher than the existing one on the database computer, the system checks whether the new software version contains newer versions of shared programs, or new shared programs. If so, the system updates the existing shared software accordingly.

If you install a version lower than the existing one on database computer, the system checks whether all necessary software for running that lower version is available. If there is shared software missing because it is no longer used with the higher software version, this missing software is installed.

Dependent software is the version-specific software of a database installation. On the database computer, the system installs an individual set of dependent software for each installed database version.
