PURPOSE: A host DBMS(DataBase Management System) tester and a testing method are provided to perform a test effectively by performing the test directly on a host system. CONSTITUTION: A host DBMS(DataBase Management System) tester includes an EDMLP(Embedded Data Manipulation Language Processor) and compiler(11), an application execution file and host library(21), a PLD(Processor Load Data)(31), a user part(100), an HDS(Host DBMS Simulator) server part(300) and an IPC(Inter Processor Channel) part(200). The EDMLP and compiler(11) converts a query language into a code. At this time the query language has an EDML(Embedded Data Manipulation Language) shape to be included by numerous application CHILL/C programs(1), and the code is recognized by a CHILL/C compiler. The application execution file and host library(21) is an execution file generated through the compiler(11). The PLD(31) is a database. The user part(100) is an An address range having an operation control instruction. At this time, the operation control instruction performs a server execution environment setup work of loading loads the PLD(31) on a server, giving a usage authority to the loaded PLD(31), and allowing a sharing. The HDS server part(300) is a C address range having numerous HDS servers and DBMS kernels. The IPC part(200) is a B address range controlling a communication between the user part(100) and the HDS server part(300) by having a sharing memory and message cue(2).
