    It included support for partitioning table rows in a database across individual disk devices, and "virtual columns" which are computed only when required. In ASE 15.0, many parameters that had been static (which required server reboot for the changes to take place) were made dynamic (changes take effect immediately).

    The eXtensible Access Control Markup Language (XACML) is an XML-based standard markup language for specifying access control policies. The standard, published by OASIS, defines a declarative fine-grained, attribute-based access control policy language, an architecture, and a processing model describing how to evaluate access requests according to the rules defined in policies.
