Computer program product for accessing database, recording medium recording database access program therein, and database access method

摘要

A computer program product for accessing a database is a program product for accessing a database by allowing a computer to execute a plurality of screen components, including a step of designating order of the plurality of screen components to be executed by the computer. Each of the plurality of screen components includes: a step of generating a part except for a "where" clause in an SQL statement in accordance with definition given from the outside for each screen component; a step of generating a screen for inputting and/or outputting data; and a step of generating the "where" clause in the SQL statement in accordance with definition given from the outside for each screen component. Since the screen component as a part of the database access program processes the steps in accordance with definition given from the outside, the screen component can be used by another database access program. Thus, general versatility is obtained and development efficiency is improved.
