I want you to say, PB has the promising, give points Power, Builder confidence! !

I have three points and peers:
First, please respect the following facts:
1, each development tool has its strengths and weaknesses
2, PB is the first real visual development tool, so so far is still the highest visualization. (Visualization is not the concept of moving with free placing, but also with code fusion programs. A plurality of coordination errors that occasionally occur in PB are due to higher visualization, familiar with side effects. Avoid.)
3, Many Features The first time with PB, which is already in Windows3.1, which is already in terms of factual standards, such as:
A, Tooltip
B, toolbar
C, status bar
D, classification standard for multiple reports in DW
4, MS's DataBind and .NET DataSet / DataView / DataReader / DataGrid, etc.
5, PB still maintains excellent object-oriented characteristics while visualization, this is enough to make current vs.net and other sweat.
Second, smart programmers use PB, and stick to PB
Five-day, a serial communication, I think that the sense of accomplishment is high, in fact, it is caused by a high frustration. Programmers are often satisfied with their poor accomplishment, and the problem is a big mistake. Top of the MS.
After a MIS system is designed, it is assumed that 50 sheets, I am currently using my own PB development library to complete the development of 80% interface one day, don't believe it? Use three days to get other 20%, which also include time to write a stored procedure, do you believe it? You can use VB / Delphi, you still don't want to get it, don't want to be Meng, I use VB than PB, I know that things take one month, and it is bug everywhere.
Third, about Sybase (DBMS)
Sybase is more pitiful. When the high-level decision-making mistake, a meeting made Microsoft's SQL Server, and almost disconnected its competitiveness in the low-end platform.
My point is: Similar to large databases, there is a good job, but it is a bit bypass, and the products of all products have no essential differences for developers (not DBA staff and performance assessment personnel). The company is so big, it is not so easy to die, and you can use it with confidence.
Fourth, about teaching materials
Don't find everywhere, Sybase Chinese website can download the official best Chinese textbook, PDF format, very new, very complete, very complete. Printing a copy is worth it, don't buy a bookstore, those books are bad.
PB has a 200-page entry enough, then look at PB's own example, the overall structure of the class is more clear and simple, and there is three months of self-feeling is no problem. One year is really a master. There is no problem. In addition, Sybase should have Chinese textbooks. PB4 1600 yuan two, a manual, a function manual, classic in the classic.
Five, a few warnings:
Many posts indicate that the products don't know, harmful, Sybase is divided into two typical versions of at least ASE and ASA, and the ASA price is more than two orders than the ASE; there is ...
