现有一个数据库，关于气象水文等等信息，包含大量数据，目前没有一个比较方便的方
法去获取有用的数据。
现在客户希望将这个数据库做成一个web services的数据源，可以根据客户不同需要返
回相应信息。
我打算做一个xml rpc的服务器，我觉得xml rpc server最简单。
大家觉得如何？大家有什么比较好的xml rpc servr推荐一下不？java或php的都可以。
数据库挺大的，包括了以往几十年的数据，但是查询量不大。

Correct/Incorrect?
1. To generate a C++ program you must edit, preprocess,
compile, and link your code.
2. Every variable has a name, a type, a value, a size,
and a lifetime.
3. Double variables are twice as accurate as float variables.
4. Variables of type int are system dependent.

Preprocess is not absolutely needed, for example:
int main() { return 0; }
The implicit temporaries do not have name, if they count.
Totally wrong. Read this: http://www.answers.com/IEEE%20754
The size (and therefore the range of representable values) of int is system
dependent.
