Abstract
The subject matter described herein relates to providing a continuous access to a database at times, including when the database is being modified or upgraded. Initially, access to an old version of a table is enabled and provided to a user. A copy of the old version is generated. Access is asynchronously redirected from the old version to the copy of the old version. A new version of the table is generated by modifying the structure of the first version of the table. The copy of the old version is accessible when the database is being modified or upgraded. When the structure is being modified, access is asynchronously redirected from the copy of the old version to the new version.
