摘要： Systems, methods, and other embodiments associated with executable templates are described. One example method includes generating an executable template from a set of template data. When an executable template is executed, the executable template creates one or more instantiated entities. These instantiated entities may then be combined with entities created from portions of the original template that were not compilable into the executable format.

摘要： Techniques for redefining a group of related objects in a relational database system by redefining a table belonging to the group of related objects and then redefining the other related objects in the group so that they are in conformity with the redefined table. The techniques permit DDL to be used to redefine a view and are also useful in a versioned relational database system for redefining the table from which the versions are generated. In the versioned relational database system which employs the technique, the versions are generated from a view. To redefine the view, the technique is employed as follows: the view's definition in the relational database system is used to make a base table that has a form which is substantially similar to that of the view. DDL is then applied to the base table to redefine it. The redefined base table definition and the definitions of the objects belonging to the versioned relational database system are then used to redefine the definitions of the objects belonging to the versioned relational database system so that they are in conformity with the base table as redefined by the DDL.

摘要： A workspace template is operative to store a collaboration workspace for successive reuse. A template script processor creates a parameterized metadata definition of a workspace. The metadata definition is written as an XML file to a storage repository. A template script processor parses the metadata XML representation to reinstantiate the workspace in the server. The workspace provides services via applications, and includes references to application objects in the applications. The server is operable to retrieve data in the application objects, modify data via the workspace, and store the modified data in the referenced application object. The workspace need not store data, since the server maps the references in the workspace to the respective services. The reused portions may encompass particular expertise gained or residing in the group, thus generally capturing and reusing the best practices of frequently used patterns, such as propagating a knowledge base of corporate practices and procedures.

摘要： Systems, methods, and other embodiments associated with template based entity transformation are described. One example method includes generating a difference set that describes differences between an existing data entity and a template. The example method may also include applying the template to the existing data entity based on the difference set and conflict resolution choices.

摘要： A versioned relational database system (VRDBS) in which versions of data contained in a relational database system are accessed by means of workspaces. Metadata in the VRDBS permits a workspace to have multiple parents. The multi-parented VRDBS performs operations including specifying that a workspace be made an additional parent of another workspace or that an additional parent be removed as a parent of the other workspace. The fact that a workspace may have multiple parents affects the manner in which merge and refresh operations are performed and the manner in which system-enforced constraints such as primary key constraints, unique key constraints, and referential integrity constraints are handled. The metadata for the VRDBMS includes a multi-parent graph for each workspace that has multiple parents. The multi-parent graph is used in the performance of the merge and refresh operations and in determining constraint violations.

摘要： Apparatus, methods, and computer program products are disclosed that maintain an association graph made up of association tuples. Each of the association tuples belongs to an access-control-policy scope that imposes an access control policy. On receipt of a client reference and a supplier reference a scope-defining entity is identified from the client reference. The scope-defining entity has an explicit access control policy. An effective supplier reference is retrieved from a set of the association tuples matching the scope-defining entity and is presented.
