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.

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 version control system is described for use in connection with a database management system to facilitate versioning of a database table, the system including a database table and a version control module. The database table comprises a plurality of records, each record including at least one data field for storing user data and at least some of the records including a version control field including version control information. The version control module is configured to, in response to a user query related to the database table and related to a version, generate an augmented query for processing by the data base management system, the augmented query relating to the user query and the version control information. The version control module facilitates association of versions of the database with respective ones of a hierarchy of states and allows conflicts therebetween to be resolved, data to be posted from child states to respective parent states in the hierarchy, and referential constraints between tables to be preserved.

摘要： Systems, methods, and other embodiments associated with an artifact type neutral container are described. This artifact type neutral container is achieved through an artifact type neutral architecture that is managed using a central type neutral registration mechanism. Queries are executed on type neutral registration tables to return data stores that store the artifacts found within a given artifact type neutral container. The data stores are queried to return the artifacts in the artifact type neutral container. The artifact type neutral container can be used in systems in which the artifact type neutral container and artifact data are stored in the same database as well as in systems in which the artifact type neutral container and artifact data are stored in different databases.

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： Systems, methods, and other embodiments associated with artifact type neutral change management are described. One example method includes maintaining an access table for each artifact in a collaborative software environment that records a most recent access of an artifact on a per user basis. An artifact type registration table is also maintained that maps each artifact type to the access table that records access information for artifacts of the given type and to a data store that stores artifacts of that type. For a given user, artifact pair, queries on the type registration table, access table, and data store are generated to return the last modification time for the artifact and the user's last access time for the artifact. This information is used to determine a change status of the artifact for the given user. This common framework can be used for artifacts of any type that are registered in the type registration table.

摘要： A fault processor in a collaboration server models collaborative operations as a state machine. The fault processor divides collaboration operations into discrete segments, in which each segment corresponds to a repository update. A state definition defines the progression of states between the segments, and defines transitions to recovery states in the event of unexpected interruption. A state log maintains the completion status of each segment in the operation, and recovery logic employs the state log to perform recovery of an abnormally terminated operation. The recovery logic computes the segments to be performed in a recovery. Compatibility logic selectively prohibits operations which may affect or be affected by inconsistencies presented prior to successful recovery. In this manner, collaboration software defined according to configurations herein identifies failures, implements recovery based on a state machine corresponding to segments of an operation, and preserves consistency by recovering the incremental segments defined by the states.

摘要翻译： 协作服务器中的故障处理器将协作操作模型作为状态机。 故障处理器将协作操作分为离散段，其中每个段对应于存储库更新。 状态定义定义了段之间的状态的进展，并且在意外中断的情况下定义到恢复状态的转换。 状态日志维护操作中每个段的完成状态，恢复逻辑使用状态日志来执行异常终止的操作的恢复。 恢复逻辑计算要在恢复中执行的段。 兼容性逻辑选择性地禁止可能影响或受到成功恢复之前呈现的不一致影响的操作。 以这种方式，根据本文配置定义的协作软件标识故障，基于与操作的段相对应的状态机实现恢复，并且通过恢复由状态定义的增量段来保持一致性。
