毕业设计(论文)外文摘要

The design and realization about material management system
Based on Delphi

Abstract: This graduation project is in view of the modern enterprise's characteristic development small information management system, the full title goods and material handling system. After inspected the enterprise goods and material handling daily service as well as has referred to other management system management systems, has determined this system demand: Realizes this kind of enterprise daily service information as well as the management automation, the solution enterprise goods sale, stocks with goods the management as well as the user manages the majority of trivial thin questions. In the function, this system may divide into the following six modules: The foundation data management, goes into storage the management, the storehouse work management, the storehouse information inquiry management, the stock control management as well as the system administration. Foundation data management: Goods foundation information, supplier information, storehouse position information and operator information input, revision, deletion; Leaves goes into storage the management: The goods leave the basic information increase, the revision, the deletion which goes into storage; Storehouse work management: Storehouse position information inquiry and storehouse inventorying information management; Storehouse information inquiry management: Leaves goes into storage the information by the different way realization inquiry, the stock inquiry; Stock control management: Leaves goes into storage the information statistics, the purchase plan increase, the revision, the deletion; System administration: User account number increase, revision, deletion, database data backup. This system regarding goes into storage, the storehouse record, in the structure selects the record method, facilitated has carried on these information recording the checkup, and guaranteed the statistical function to have the correct result. Through the hypothesis user's jurisdiction, produces the different operation jurisdiction to the different user, enables the user to be allowed each duty, has facilitated to user's management. Moreover has used the unified contact surface, and provided the massive operations to prompt as well as to make a mistake the information, the big convenient user used this software, simultaneously also reduced the possibility which made a mistake, has guaranteed the data accuracy, the integrity and the uniformity. This software system causes the enterprise to realize the commodity turnover storehouse management information, reduced manpower cost paying, in the certain degree enhanced enterprise's benefit.
