摘要： A method and mechanism are provided for accessing data. Values are stored for a set of context attributes associated with a session between a database user and a database server. The database system includes an attribute setting mechanism that selectively restricts access to the set of context attributes based on a policy. During the session, the database server executes a query that contains a reference to one or more of the context attributes. For example, the query may contain a predicate that requires a comparison between a context attribute value and a constant. The database server processes the query based on current values of the one or more of the context attributes referenced in the query. A mechanism is also provided for dynamically attaching predicates to queries, where the predicates are attached based on a policy. For example, the database system detects that a query is issued against a database object. Prior to executing the query, a policy function associated with the database object is invoked. The policy function creates a modified query by selectively adding zero or more predicates to the query based on a policy associated with the database object. The modified query is then executed.

摘要： The present invention provides a computer implemented method and apparatus for storing and retrieving data in a database management system (DBMS) in multiple languages, simultaneously, using a fully-populated Sub-Table. In one embodiment, the method and apparatus include generating a Base Table and a Translation Sub-Table. The Base Table includes base rows, each having a primary key and zero or more untranslatable values, exclusive of translatable data values. The Translation Sub-Table includes sets of sub-table rows, wherein each set of sub-table rows corresponds to a base row in the Base Table. In each set of sub-table rows, a sub-table row is provided for each operational language having at least one translatable data value corresponding to the primary key of the respective base row.

摘要： Approach for versioning of documents is described. A version accumulator structure stores one or more version values indicating different versions of a data object. The data object is decomposable into a plurality of nodes. One or more copies of each node of the plurality of nodes are stored, where the one or more copies are associated with non-overlapping version ranges. A first request to perform a change to the data object is received. The first request specifies an effective version value for the change, which involves a particular node. The change is performed based on the effective version value and without making a deep copy of the data object. A second request to retrieve a certain version of the data object is received. The certain version is retrieved based on the version ranges associated with the one or more copies of each node of the plurality of nodes.

摘要： Techniques for allowing an application designed to store data for one group of users to store data for a plurality of groups of users include modifying the application to cause the application to indicate a routine to a database server that stores data for the application in a database. The routine provides modifications to queries of the database, which limit access based on the groups to which belong users that cause the queries to be submitted. In response to receiving a query involving the database and caused by a particular user, the database server locates the routine, and, prior to executing the query, modifies the query. Modifying the query includes invoking the routine. The modification to the query thereby limits access of the particular user to data that is associated with the group of users to which the particular user belongs.

摘要： A method and apparatus are provided for storing data of multiple enterprises in a set of database objects in a database system and allowing multiple enterprises to interact with the database system as if those database objects contained only their data. According to an aspect of the present invention, a database command issued against a database object by a user is modified by adding predicates that limit access to data associated with the enterprise in which the user has data access. The predicates may specify conditions based on a column in the database object that identifies the enterprise. When a user issues a database command to add data to the database object, the column is populated in a manner transparent to the user. The data in the database object that is associated with a particular enterprise is stored in a separate tablespace.

摘要： A dynamic memory allocator in a computer assigns portions of memory into a large number of slots that include zero or more memory blocks of equal size. Free lists identify memory blocks, corresponding to a slot size, not currently in use in the computer. Software programs generate requests, including a size, for a memory block. The size of the requests are rounded up to the nearest slot size. To allocate a memory block, the free lists are searched, using a bit map index or a hierarchical bit map index, to identify an available memory block to accommodate the memory block requested. The dynamic memory allocator handles large block allocations different from small block allocations. A virtual memory allocator stores a plurality of pointers to identify one or more virtual pages of memory for allocation to the dynamic memory allocator.

摘要： Files of software to be installed in a computer are packaged as follows. A source file is prepared to contain at least a declaration of an array of sufficient space to accommodate the files to be packaged. The source file is compiled into an executable file. Thereafter, the array in the executable file is overwritten with data from each file being packaged. Depending on the embodiment, the address of where each file begins in the executable file and each file's name may be stored in the same executable file or in a different file. The stored file names are used to identify an address of a file from its name, when the named file is first accessed. In several embodiments, the operating system loads the executable file as a library that is automatically shared by multiple instances of the application (or by multiple applications), to efficiently use physical memory.
