Delphi is a new generation of visual development tools developed by Borland, available on Windows 3. x, Windows95, WindowsNT and other environments. It has a visual integrated development environment (IDE) that uses an object-oriented programming language ObjectPascal and a component-based development framework. Delphi provides more than 100 ready-to-use widgets. With these widgets, developers can quickly build application systems. Developers can also modify parts based on their own needs or write their own parts using Delphi itself.
The main features are as follows:
(1) Compile directly to generate executable code, compile speed. Because the Delphi compiler uses conditional compilation and select linking techniques, the executable files it generates are more refined and run faster. In terms of processing speed and accessing servers, Delphi's performance is much higher than other similar products.
(2) Supports the transfer of access rules to the client or server separately, and allows developers to create a simple set of parts or components, encapsulate all the rules, and be independent of the server and client, all Data transfer is accomplished through these components. In this way, the requests to the server and the amount of data transmission on the network are greatly reduced, and the application processing speed is increased.
(3) provides a number of quick and easy development methods that enable developers to complete a wide variety of applications with as few repetitive tasks as possible. Using project templates and expert generators, the project's architecture can be quickly established and then gradually refined according to the actual needs of users.
(4) Reusability and extensibility. Developers no longer need to program common widgets such as tabs, buttons, and dialog boxes. Delphi contains many reusable widgets that allow users to control the development of Windows.
(5) has a powerful data access function. Its data processing tool BDE (BorlandDatabaseEngine) is a standard intermediary software layer, can be used to process the current popular data formats, such as xBase, Paradox, etc., but also through BDE SQLLink directly with Sybase, SQLServer, Informix, Oracle and other large Database Connectivity. Delphi can be used to develop system software as well as application software development.
