For over four decades COBOL has been the dominant programming language in the business computing domain. In that time it it has seen off the challenges of a number of other languages such as PL1, Algol68, Pascal, Modula, Ada, C, C++. All these languages have found a niche but none has yet displaced COBOL. Two recent challengers though, Java and Visual Basic, are proving to be serious contenders.
COBOL's dominance in underlined by the reports from the Gartner group.
In 1997 they estimated that there were about 300 billion lines of computer code in use in the world. Of that they estimated that about 80% (240 billion lines) were in COBOL and 20% (60 billion lines) were written in all the other computer languages combined .
In 1999 they reported that over 50% of all new mission-critical applications were still being done in COBOL and their recent estimates indicate that through 2004-2005 15% of all new applications (5 billion lines) will be developed in COBOL while 80% of all deployed applications will include extensions to existing legacy (usually COBOL) programs.
Gartner estimates for 2002 are that there are about two million COBOL programmers world-wide compared to about about one million Java programmers and one million C++ programmers.

因为信息技术与实际应用在目前的中国还是水和油的关系,换句话说,目前能够在信息技术应用上能说上话的全他妈的是混蛋.都在扯蛋呢,用C来扯蛋比较方便,另外他们也说不上用别的东西的优势,只好不动了.
什么语言都可以
我们用的是cobol...
我们还是用的ESQL/C， 呵呵， informix

有两个原因：
1。是历史遗留问题，由于以前语言没这样多，只好选C，C++
2。C和C++对写第层，交易通讯方面的程序存在一定的优势
我弄不懂，为什么银行业务系统软件非要用C/C++来开发？
是何原因？ 不是说基于RPG（As/400上），Cobol（基于S/390）的开发最多吗？
C最多了，但是现在一些报表系统，WEB界面的东西JAVA也用得多了。
用C和C＋＋语言开发。
