摘要： 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.

摘要： A distributed content entity includes a protection specification and an information entity, in which the protection specification and the information entity are attached and transported together. The protection specification includes information for controlling the use of the information entity. A framework generates the distributed content entity, in which the framework includes a protection specification unit storing the protection specification and including an access control enforcement manager and an enhanced access control enforcement manager; an information unit for storing the protected information entity; and an access checking unit connected to the protection specification unit and the information unit. The access checking unit checks whether a user has a privilege to access the protected information entity based on the protection specification and the access control manager, and checks whether the requested access meets conditions determined based on the protection specification and enforced by the enhanced access control manager. An example of the enhanced access control manager is a terms and conditions enforcement manager for enforcing the terms and conditions of an agreement relating to permitted uses of the protected information entity.

摘要： In a searching for library documents that match the content of a given sequence of query words, a set of equivalent words are defined for each query word along with a corresponding word equivalence value assigned to each equivalent word. Target sequences of words in a library document which match the sequence of query words are located according to a set of matching criteria. The similarity value of each target sequence is evaluated as a function of the corresponding equivalence values of words included therein. Based upon the similarity values of its target sequences, a relevance factor is then obtained for each library document.

摘要： 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.

摘要： 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.

摘要： A multi-tiered indexing method is disclosed for a partitioned table in a parallel or distributed database system. A Local Index is created and maintained for each partition of the table and a Coarse Global Index is created and maintained. The Coarse Global Index identifies the indexed partition(s) by partition identifiers (PIDs) and associates the individual Index Key Values with their target partitions so that an access request with a highly partition-selective search predicate on the Index Key can be quickly and easily directed to the target partition(s) for processing. An index maintenance locking protocol is also disclosed which handles the insertion and deletion of index entries and assures the consistency between the Local Index entries and the Coarse Global Index entries during concurrent index accesses by different transactions. The locking protocol minimizes locking only to those cases involving an inserted or deleted key and to the key following and possibly the key preceding the inserted or deleted key to allow high concurrency between simultaneous Readers, Inserters, and Deleters. This method enhances the efficiency of complex query evaluation and index maintenance and attains a high throughput for transaction processing.
摘要翻译：公开了一种用于并行或分布式数据库系统中的分区表的多层索引方法。为表的每个分区创建并维护本地索引，并创建和维护粗糙全局索引。粗糙全局索引通过分区标识符（PID）标识索引分区，并将各个索引关键值与其目标分区相关联，以便在索引键上具有高度分区选择性搜索谓词的访问请求可以快速轻松定向到目标分区进行处理。还公开了索引维护锁定协议，其处理索引条目的插入和删除，并且在不同事务的并发索引访问期间确保本地索引条目和粗全局索引条目之间的一致性。锁定协议最大限度地将锁定仅限于涉及插入或删除的密钥的情况以及插入或删除的密钥之后的密钥以及可能的同时读取器，插入器和删除器之间的高并发性的密钥。该方法提高了复杂查询评估和索引维护的效率，实现了交易处理的高吞吐量。
