[This is preliminary documentation and subject to change.]
CIMOM currently supports the WBEM Query Language (WQL) to handle query processing. WQL is a subset of the ANSI standard Structured Query Language (SQL) with WBEM-specific extensions. Some extensions support event registration and notification, while others support relationships between classes and instances. WQL is a read-only query language in that it cannot be used to update, insert, or delete data. WQL can only be used to retrieve information.
