摘要： When a database area multi-written or replicated in an external storage unit is separated, a database management system writes consistent data into the external storage unit. A method and system capable of controlling a timing of separating the replicated database area is provided. Furthermore, new data directory information necessary to access the replicated database is dynamically added based on the data directory information of the replication source database. A method and system capable of selecting whether to access the database which is the source of the replication or access the replicated database are provided. Thus, when the database area multi-written or replicated in an external storage unit is separated and physical replicated databases are created, it is possible to maintain consistency of the replicated databases while continuing transaction processing.

摘要翻译： 当在外部存储单元中多重写入或复制的数据库区域被分离时，数据库管理系统将一致的数据写入外部存储单元。 提供了一种能够控制分离复制数据库区域的定时的方法和系统。 此外，基于复制源数据库的数据目录信息动态地添加访问复制数据库所需的新的数据目录信息。 提供了一种能够选择是否访问作为复制源或访问复制数据库的数据库的方法和系统。 因此，当在外部存储单元中多重写入或复制的数据库区域被分离并且创建物理复制数据库时，可以在继续事务处理的同时保持复制数据库的一致性。

摘要： A definition tool of the present invention declares columns which are concealed in external tables to a multi-database server. The multi-database server controls a decomposition and an execution of query messages such that the multi-database server does not perform an arithmetic using the concealed columns. The external database server encrypts the data of concealed columns in tables of query result tables. The multi-database server designates a range to be decrypted at the time of acquiring and integrating respective result tables. A client program acquires an integrated result table and decrypts the designated range. Since the data encrypted by the external database server is decrypted by and is referred to the client program, it becomes difficult for the multi-database server to refer to a content of the concealed columns.

摘要： In a method for supporting the design of a plurality of programs distributed on a network and operated through the communication between the programs, each program is defined, a relation between programs is defined, interface information of each program is defined, and the interface defined for each program is converted into an interface definition language (IDL) format to generate an IDL file. The definition of each program and the definition of the relation between programs are performed by providing a graphic display screen to which a program represented by a symbol and a relation between programs represented by an arrow are inputted as definition information by a user. The definition of interface information is performed by inputting information defined by the user in an interactive manner.

摘要： The present invention provides techniques for answering a user's query to a database system. An embodiment provides a database querying method in which a first data item is obtained from a Data Base Management System (DBMS) database table in response to a query request. A second data item is obtained by referencing a DBMS updated log file, having log data associated with the first data item, for example a timestamp. The first and second data items are then integrated and returned as an integration result to the query request. In one embodiment the first and second data items are integrated in a virtual table in accordance with a predetermined business rule.

摘要： In comparison to unnecessary page generation of the prior art, the page generation time according to the current invention is substantially reduced, and the generated page is efficiently accessed. Since in response to at least one of a predetermined set of update events, a page is dynamically generated in advance of a user page request and the dynamically generated page is stored, the current invention allows the efficient page access. The use of the prior art technologies such as proxy servers in combination further improves the cost of transmission of the page to the user according to the current invention.

摘要： In comparison to unnecessary page generation of the prior art, the page generation time according to the current invention is substantially reduced, and the generated page is efficiently accessed. Since in response to at least one of a predetermined set of update events, a page is dynamically generated in advance of a user page request and the dynamically generated page is stored, the current invention allows the efficient page access. The efficient page access is accomplished by storing the dynamically generated page as a static page at a URL identified by a page access call with an argument. Thus, the user accesses the previously generated dynamic page at a high-speed. The use of the prior art technologies such as proxy servers in combination further improves the cost of transmission of the page to the user according to the current invention.

摘要： The present invention relates to an optimization method in a database management system having the function of accessing external databases. Conventionally, whether functions contained in a query can be executed in external databases depends on a database management system having the functions, and therefore there has been a problem in that a database utilization method cannot apply to query optimization and query execution performance is reduced. To solve the above problem, a database management system having the function of accessing external databases is provided with an optimization step comprising the steps of: obtaining specification about whether to execute functions in a query in external databases; determining whether data referred to in a query is confined to one database; and determining whether a user specifies that the functions in the query are executed in external databases.
摘要翻译： 本发明涉及具有访问外部数据库的功能的数据库管理系统中的优化方法。 通常，查询中包含的功能是否能够在外部数据库中执行取决于具有该功能的数据库管理系统，因此存在数据库利用方法不能应用于查询优化并且查询执行性能降低的问题。 为了解决上述问题，提供了具有访问外部数据库的功能的数据库管理系统，其优化步骤包括以下步骤：获取关于是否在外部数据库中执行查询中的功能的规范; 确定查询中引用的数据是否限于一个数据库; 以及确定用户是否指定在外部数据库中执行查询中的功能。
