The Charging Manageable System In The Parking Lot

With the development of economy in our country, the process of modernization is becoming faster and faster. Many people have owned their own cars , which results in the increase of autos in various kinds of big public parking lots. The reservation of autos has become an increasingly important social problem. The number of parking users is very large and the parking time is very short, which requires a set of accurate system with simple operation to solve the problemNow manual charging method is widely adopted and there are a lot of flaws to a large extent , which results in disordered system in parking lots.This article mainly introduces self-designed charging management system in parking lots aiming at existed problems and makes detailed introductions to the system from development tools, the choice database, programming mechanism and principles, the function of system softwares, mode-division, the design of database models , detailed realization and other aspects.The charging system adopts Visual Basic6.0 as database development platform. As Visual Basic can connect with many kinds of database, which means a lot of popular database can connect with Visual Basic, Visual basic can be used to develop corresponding top applied program. Compared with the common database system, Visual Basic has a lot of strong points such as being simple, flexible and expanded.The system database adopts Microsoft Access which is not only a database but a strong data manager. Microsoft Access is a kind of desk database management system, but it's different from traditional ones. Microsoft Access is the inner database of Visual Basic, i.e. default database. The"inner"here has two meanings: one means the database built by Access (.MDB) can be used in Visual Basic; the other means Visual Basic can directly build Access database, so in Visual Basic"Access database"and"Visual Basic"have the same meaning.The system uses MFC to visit ODBC database. MFC has sealed more complicated ODBC API and provided simple allocated interface, which greatly simplified the development of the applied program of the database. The programmer need not know much about the details of ODBC API and SQL. They can finish most of the operation to database making use of MFC. The system uses ADO to operate database. ADO is the new interface...
