Abstract: Systems and methods for generating a platform-independent metadata catalog framework of a database system are disclosed. These include receiving, at the database system, a metadata object, and determining a version of the received metadata object. Responsive to determining that a metadata catalog, which has catalog entries associated with unique versions of metadata objects, does not include a catalog entry associated with the version of the received metadata object, a catalog entry in the metadata catalog is created. The created catalog entry is then associated with the version of the received metadata object. Furthermore, a version number based on the version of the received metadata is generated, which is associated with the created catalog entry. Related apparatus, systems, techniques and articles are also described.

Each retrieved field of the first portion may be presented to a user, along with a field indicator for at least one field of a second portion of the multiple fields, with each of the fields of the second portion having a corresponding size at least as large as the threshold size. In response to a selection of the field indicator, at least one field of the second portion may be retrieved and presented to the user.

Abstract: For each statement of an application executing in a debugger script-controlled debugger session, if the statement comprises an authorization check for a user in regard to an object, and if the debugger includes a set of authorization rules associated with the object, then execution of the application is discontinued. Application values for each data field of the object are obtained. These values are compared to respective values specified by each rule of the set of authorization rules. If the current values do not match values specified by at least one of the rules, the authorization check is executed normally. If the current values do match values specified by at least one of the rules, then: the authorization check is skipped, a pass or fail value for the authorization check is registered by the executing application according to the at least one rule, and execution of the application continues normally.
