How to Handle Parts Lookups in Clients of a Vehicle Parts Search System

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle parts retrieval system, and more particularly, to a method for processing parts lookup at a client in a three-tier (host-server-client) system used when checking a stock of parts at a business office.;The features include the creation of an inquiry screen for entering information such as business offices, warehouse divisions, sales offices and part numbers, and creating data to be sent when an inquiry button is entered by checking whether an inquiry button is entered. If it is not entered, check whether the end button is input and perform other processing if it is not entered. If the end button is not input, the first step is to terminate the process; and create data to be transmitted to the server to communicate with the server. If the connection is not established as a result, an error message is outputted, and it is returned to the step of judging whether the inquiry button is inputted. If the connection is established, it is checked whether data is transmitted to the server, and if it is not transmitted, an error message is outputted. The second step of returning to the data creation step to be transmitted, and if the data has been transmitted, The third step is to receive the data and analyze the transmitted data to check whether there is an error in the data, and if the error does not occur as a result, to output the analyzed data on the screen. If there is data to be transmitted by checking for the presence of data, the process returns to step S5, and if not, the process returns to step S2.
