1. PowerBuilder Introduction
PowerBuilder was a leader in the rapid development platform for Management software in the 1990 's, and was suitable for developing client/server architecture applications based on relational databases. Based on its patented DataWindow technology, PB Development database management software is more than 10 times times more efficient than other development platforms, and its advanced compilers make the program run fast.
After observing the PowerBuilder development demonstration, Bill Gates was excited to call Microsoft's development director to say, "You must see this." Many of Microsoft's internal management software is developed using PowerBuilder, although they also produce development tools themselves. Today, much of the management software in the United States and Canada is based on the PB platform. Any software development tool has its strengths and weaknesses, and PB is a razor in its area of expertise, and the development of application software is highly efficient. But for the multilayer architecture, the Web architecture, PB is a bit stretched.
The latest version of PB has been fully integrated into Microsoft's Visual Studio platform, becoming a powerbuilder.net. In addition to the datawindow.net, PB has actually been reduced to the same powerscript.net language as C #. 2012 PB's parent company Sybase was acquired by SAP, the management software giant, and its future development is confusing.
PowerBuilder is a powerful and easy-to-use front-end database development tool that enables rapid development of large database application systems.
PB is a distributed database front-end development tool with graphical interface, programming language is powerscript. It supports both Windows and UNIX operating systems.
PB is a C/s application development tool. It follows the principle of event-driven programming.
2, PB is always referred to the object, PB in the end there is no such as Java class and instance concept?
There are, as follows:
Object-oriented technology-->PB
Class-to-object (such as window)
Properties--The object's own properties, etc.
Methods--divided into events and functions
3, PB can do distributed development?
No direct support, PB is better at C/s development.
4, what is the uniqueness of PB?
DataWindow Technology
5, what is 4GL?
The development of the fourth generation language is a problem-oriented, procedural programming language. 4GL of Representative software systems are: PowerBuilder, Delphi and INFORMIX-4GL and so on.
