How to effectively manage the large number of goods is every supermarket operators need to urgently solve the problem. Traditional artificial management has low efficiency, poor confidentiality, easy loss of data, the cost is high, far does not apply to development scale is being more and more big supermarket. Then, with the progress of puter technology, the supermarket enters sells saves the management system came into being. The supermarket enters sells saves the management system has retrieves, the search rapidly convenient, the reliability high, thereserves big, the secrecy good, the long life and low cost etc. These merits can effectively improve the efficiency of the supermarket management, saving the cost of supermarket management, is the enterprise scientific, systematic management, and the important condition of the world. The supermarket enters sells saves the management system is a typical management information system (MIS), its development mainly includes the backstage database the establishment and maintenance of and the front interface program development two aspects. The supermarket enters sells saves the management system in the design embodies the human nature and the spirit of peopleoriented. Friendly interface design, simple and intuitive, easy to operation. This system USES SQL database, using c language development language, to realize the query system, entry, add, delete, and other functions. Key words: the supermarket enters sells saves the management ystem。界面設(shè)計上親切友好，簡單直觀，便于操作。 超市進銷存管理系統(tǒng)是一個典型的信 息管理系統(tǒng) (MIS)，其開發(fā)主要包括后臺數(shù)據(jù)庫的建立和維護以及前端界面程序的開發(fā)兩個方面。超市進銷存管理系統(tǒng)具有檢索迅速、查找方便、可靠性高、存儲量大、保密性好、壽命長、成本低等優(yōu)點。傳統(tǒng)的人工管理具有效率低、保密性差、容易丟失數(shù)據(jù)、成本高等問題，已經(jīng)遠遠不適用于發(fā)展規(guī)模越來越大的超市了。目錄 目 錄 設(shè)計總說明 .................................................................
