摘要:
A method, apparatus and article of manufacture for a universal calling interface for executing a stored procedure in a computer. Parameter information is retrieved from a database catalog and the computer performs type checking against the user-entered parameters. If there is not a type mismatch then the computer executes the stored procedure without the user entering information about the parameters such as address and type.

The present invention discloses a method, apparatus, and article of manufacture for tracking and propagating state changes in a message-driven computer program. In accordance with the present invention, a program in the memory of a computer receives a notification signal indicating that an event has occurred and transitions a first component from a current state to a new state based on the notification signal, wherein the states are represented by discrete objects or components. The computer program propagates, to a second component subordinate to a first component representing the new state, a signal indicating the new state of the first component.
摘要:
Provided is a method, system, and program for performing workflow related operations. An application programming interface call (API) is received to perform a workflow related operation. A determination is made of at least one stored procedure call associated with the received API. The determined at least one stored procedure is then called to cause the execution of one determined stored procedure on a database server to perform the workflow related operation of the API.
摘要:
System and method for authorizing access to an entity by a user, by binding an access control list to each entity; specifying for the user a set of user privileges; intersecting the access control list and set of user privileges in a compiled ACL table; incrementally refreshing the compiled ACL table responsive to run time modification of relevant tables containing the access control list and set of user privileges; and referencing the compiled access control list to authorize a user request to access an entity.

Provided is a method, system, and program for performing an Input/Output (I/O) operation on an object during execution of a workflow comprised of nodes. A plurality of objects are stored in one of multiple data stores, wherein each object is identified within the data store with a first object identifier. A workflow packet references at least one object with a second object identifier, wherein the second object identifier indicates one of the data stores and the first object identifier of the referenced object in the data store. An I/O request for one target object referenced by one second object identifier in the workflow packet is received from one node. A determination is made from the second object identifier for the target object the data store and the first object identifier of the target object. The I/O request is performed on the target object at the determined first object identifier in the determined data store.
摘要:
Access to system and user defined entities (objects, data items, or the like) is managed by a content manager. A privilege grants a user an ability to access system such controlled entities. An item is an atomic user data entity stored in the CM library server. A privileges table is used to store system and user defined privileges. A privilege is represented by a row in the table. Each privilege has a unique privilege code, with codes 0 to 999 reserved to store system-defined privileges and codes beyond 999 open for user-defined privileges thus allowing application specific privileges to be added without limit.
摘要:
A method, apparatus, and article of manufacture for an object-oriented framework for managing access control in a multimedia database connected to a computer is provided. A datastore access control object is generated for the datastore, wherein the datastore access control object enables controlling access to the datastore. An access control list object is manipulated with the datastore access control object to set access privileges.
摘要:
An architecture to enable search gateways as part of a federated search supports searching for data in one or more heterogeneous data sources. The one or more heterogeneous data sources are within a computer system. Initially, a request for data is received at a federated data source. From the federated data source, data is retrieved from one or more of one or more terminal data repositories or one or more search gateway data sources.
摘要:
Provided is a method, system, and program for maintaining workflow related information. At least one table is provided in a database storing workflow related data. A plurality of methods are provided, wherein each method specifies an operation to perform on the workflow related data in the at least one table, and wherein each method is associated with one stored procedure call. One stored procedure is provided in the database for each stored procedure call and corresponding method, wherein the stored procedure includes a plurality of database statements to perform the method operation. One stored procedure is executed in the database to perform the corresponding method operation on workflow related data in one table.
摘要:
A design and implementation of a client/server framework for federated multi-search and update across heterogeneous datastores. In particular, a technique for manipulating data in one or more heterogeneous datastores at a computer is provided. An object-oriented model is provided for integrating one or more heterogeneous datastores with a federated datastore. One or more heterogeneous datastores and a federated datastore are generated based on the object-oriented model. The generated datastores are organized into a federated composition.
