Abstract
Relational database systems are disclosed that are enabled to operate with versioned metadata. The relational database system includes a lock manager, a transaction manager and a version aware metadata storage and cache configured to store to store and manage versions of metadata, to determine which of such versions should be visible at any given point in time, and to enable creation of the proper versions of metadata. In an aspect, the transaction manager manages transaction identifiers and their associated start times, abort times and/or commit times. Such data enables determination of transaction visibility, and consequently the metadata version visibility, for any point in time. In an aspect, such metadata versioning support enables snapshot isolation of metadata transactions.
