How to change data fast in database management system (DBMS) in analysis system

摘要

The present invention relates to a fast change method of data through a DBMS in a distributed system, to provide a user with an effect such as through a DBMS in an environment based on main memory, and to actually change the data through a DBMS. A first step 21 for generating information necessary for fast change of data in the data manipulation word processor EDMLP; A second step (22 to 28) of checking the existence of the tuple to be changed if it is within the relation range after obtaining the address in the main memory of the tuple to be changed; And a third step (29, 30) of calling the DBMS using the change information of the attribute created at compile time to perform the change, and outputting the result of the fast change and terminating it. The process of accessing a fast and desired tuple regardless of the location of the tuple in the relation is the same, real-time processing of the application, and it can be used in a general-purpose main memory DBMS. This can shorten the application development time.
