摘要： A database management method enables an improved efficiency processing action in a computer wherein manipulation of data from a table is required in accord with a query request, wherein the table is stored remotely from said computer and at least some data in the table includes large data objects (LOBs). The method includes the steps of: responding to the request by transmitting a query to the table; configuring a result set from the table in response to the query, wherein the result set includes one or more unique identifiers of any LOB data associated with the result set; receiving the result set and performing a data manipulation action on data contained in the result set to form a response; transferring the response to the query requester; and accessing LOB data from the table that is referenced by the one or more unique identifiers in the result set and causing transfer of the LOB data to the query requester.

摘要： A heterogeneous database system is described which includes plural database systems, one of the database systems acting as an interface (i.e., system manager). The system manager performs functions which provide an application program with transparent access to the entire database system. The system manager includes a memory for storing (i) a matrix of functional capabilities of each of the plural databases, (ii) a catalog of functions that are supportable by various databases and (iii) and entry matrix for providing an interface function between a user and the system manager. A processor is present in the system manager; and is responsive to a user entry, via the entry matrix, with respect to a functional capability of one of the plural databases, to alter a matrix of functional capabilities pertaining to the database. The alteration is carried out in accordance with a corresponding functional capability entry in the catalog. If a user entry is received which refers to a database for which no entry exists in the matrix of functional capabilities, the system manager presents an entry matrix in a form which reflects default functional capabilities. Thereafter, the default capabilities may be altered by a system administrator to reflect the capabilities of the new database.

摘要： A method enables a computer to manipulate data from a table in a remote database in accord with a query from a query requestor, wherein at least some data in the table includes large data objects (LOBs). The method includes the steps of: responding to the query by configuring a database query and determining (i) if a response to the database query requires transfer of LOB data from the table and if yes, and (ii) the LOB data can be transferred in response to the database query without a data manipulation which uses the LOB data or (iii) a data manipulation required in response to the database query which uses the LOB data can be performed at the remote database, then designating the LOB data for "streaming"; dispatching the database query to the remote database and receiving a result set from the table from the remote database in response to the query; and storing the result set and causing any LOB data which has been marked for streaming to be then dispatched to the query requestor without being written to disk.
摘要翻译：一种方法使得计算机能够根据来自查询请求者的查询操纵来自远程数据库中的表的数据，其中表中的至少一些数据包括大数据对象（LOB）。该方法包括以下步骤：通过配置数据库查询来响应查询，并确定（i）对数据库查询的响应是否需要从表中传输LOB数据，如果是，则（ii）可以转移LOB数据响应于没有使用LOB数据的数据操作的数据库查询，或者（iii）可以在远程数据库处执行响应于使用LOB数据的数据库查询所需的数据操作，然后指定用于“流”的LOB数据 “; 将数据库查询分派到远程数据库，并响应于查询从远程数据库从表中接收结果集; 并且存储结果集并且使得已经标记为流的任何LOB数据然后被分派到查询请求者而不被写入到盘。
