A system and method for authorizing access to a controlled entity by a user. A set of user privileges is provided for user; and a content manager intersects an access control list (ACL) and the set of user privileges to authorize access. Binding level control indicia selectively binds an access control list (ACL) to the controlled entity at item type, item, mixed, or library binding level. An item type comprises one or more component items with each component item having one or more item views which together form an item type view. A content manager is responsive to the binding level to perform ACL checking for authorizing access to the controlled entity by the user.

A method, system and article of manufacture for reducing a deadlock probability during transaction processing in a computer network system having a plurality of users of the network system that comprises a content management system performing implicit transactions via API calls to a library server on a plurality of entities shareable by users of the network. The computer-implemented method comprises invoking a transaction sequence in response to a transaction request, performing a prepare portion of the transaction sequence, implicitly committing the prepare portion of the transaction, performing an update portion of the transaction sequence, and fully committing the transaction.

A content management system provides versioning capability that can either be controlled by the client application or be transparent thereto. Control of document versions depends on the root and child component attributes that are defined by the hierarchical structure of the document. When a document is updated, the present system performs any or all of the following scenarios as desired by the user: replace the existing attribute values stored in the root component instance for a specified document; replace the existing attribute values stored in a specified child component instance for the specified document; add a new child component instance into the hierarchical structure for the specified document; or delete an existing child component instance from the hierarchical structure for the specified document.

System and method for item versioning in a content mangement system

A content management system is provided including a server computer and a client computer. The server includes a data repository and a stored procedure. The disclosed methodology provides a way of handling parameter passing of structured data for stored procedures in the system. The system is capable of both encoding data into a structured data format and decoding data from the structured data format. The structured data format employs a binary large object (BLOB) and character large object (CLOB) to achieve handling of fixed length binary data and variable length character data. Advantageously, the stored procedure interface need not be rewritten and customized for each stored procedure in the server.

Methods, systems, and program products for managing multimedia content. These are built upon a combination of a high level content model for specific multimedia content types and a low level physical for mapping to a data engine. The method, system, and program product include representing multimedia content management objects and managing the objects in a relational database. The relational database is adapted for representing data in a plurality of relational database tables, where each of the relational database tables has at least one row with a plurality of columns. Content is managed by associating the object as an item to a row in a first relational database table; and associating additional components, if any, of the object to additional relational database tables.

Method, system, and program product to support multiple content-management data models

A content management system is provided including a plurality of tables forming a tree-based storage hierarchy. The system includes a library server having a stored procedure which creates a hierarchical tree-based storage structure having any number of child components horizontally and any number of component types vertically thus specifying a tree topology. Advantageously, a single invocation of the stored procedure will create the specified tree-based data storage structure which is stored in the library server.

Content management system and methodology for implementing a complex object using nested/recursive structures

A relational database is disclosed which includes a number of target tables each exhibiting a different type, such as a general contact table, a personal contact table and a department contact table. The relational database includes a super-column which is divided into a number of columns corresponding to the number of types of target tables. A respective column is allocated in the super-column for each of the types of the target tables. Valuable system memory space is consequently conserved. Multiple-typed tables and multi-targeted tables are supported, and multi-version data storage capabilities are provided.

Version-enabled, multi-typed, multi-targeting referential integrity relational database system and methodology

A content management system is provided including a plurality of tables forming a tree-based storage hierarchy. The system includes a stored procedure which enables information to be retrieved from different arbitrary locations throughout the storage hierarchy. Advantageously, the system retrieves information from both simple and complex tree-based storage hierarchies.

Content management system and methodology employing a tree-based table hierarchy featuring arbitrary information retrieval from different locations in the hierarchy

A content management system is provided including a plurality of tables forming a tree-based hierarchy for storing information such as item information. An information retrieval interface is provided to facilitate retrieval of information from the tree-based table hierarchy. The number of cursors employed for retrieving information is dynamically variable with the number of tables in the hierarchy. Advantageously, the content management system permits tables to be added or appended to the initial tree-based table hierarchy after the database is created. The number of cursors is dynamically varied to accommodate the additional cursors needed to query the additional table or tables.

Managing a content management system. The content management system is one that is configured and controlled to establish a connection between a client and a library server, generate a transaction identifier and insert, a record for the transaction in a tracking table associated with the library server, pass transaction data from the client to a resource manager, process the transaction at the resource manager and record transaction data in a tracking table associated with the resource manager. The resource manager returns transaction success/failure data to the client, compares activity recorded in the tracking tables, and takes corrective action based upon the activity comparison.
