Abstract: Various systems and methods for selective revalidation of data objects are provided. In one example, a computer-implemented method includes updating a target data object of a database system according to a definition statement, and determining whether the definition statement changes one or more object properties of the target data object. In response to determining that the definition statement changes the one or more object properties of the target data object, the method includes revalidating data objects depending on the target data object. In response to determining that the definition statement does not change the one or more object properties of the target data object, the method includes not revalidating the data objects depending on the target data object. In this way, database management performance and speed may be improved while maintaining validity of data objects in a database.
