【正文】 ented method, the inheritance and polymorphism encapsulation characteristics such as we develop applications that have great reusability and expansibility,while it is in software engineering applications of the important targets. At present,due to the development of work technology,many different kinds of operating system platform in the inter use,it is also about the application crossplatformability put forward higher request, and will provide a good PowerBuilder crossplatformability, for instance, using PowerBuilder in various objects platform development WINDOWS can be easily applied to the unix operating platform, because the crossplatformability PowerBuilder support makes the application from a platform to another platform is plex. Bee In order to offer customers all aspects of PowerBuilder support, has its own programming language, the language powerscript besides providing basic flow control statements,and also provides hundreds of function of objects and offer to manipulate,ole,etc,such as dde support. In addition, we can define your own functions, with a particular is the time when the part PowerBuilder to understanding and knowledge of the various functions. PowerBuilder provide A great characteristic is PowerBuilder put forward the concept of data window object. Data window object is a type of object PowerBuilder,and other objects of different data window object is designed to access the database services,data window object we define data sources and data display style, so in applications we can concentrate entirely on the execution of the program flow control, and don39。t care specific data sources, because we have window object in data definition good data sources. If need to use the database of different data also modify data window object. Especially in the data that was in the window object PowerBuilder provides abundant data display mode, can satisfy all sorts of different needs. In a new version of PowerBuilder provides a base class library,its application for PFC provides many developing reusable predefined class and object
