Types of software Evolution
Software evolution is like biological evolution, some mutations are beneficial to species, and some are harmful.
The key to differentiate the type of software evolution is whether the quality of the program is increased or decreased in this process. The second is that this evolution is the result of the process of the construction of t
Not long ago, I read a book "Web2.0 New SOA business language". This book author Sandy Carter found the point of convergence between Internet collaboration technology Web2.0 and Enterprise SOA, the combination of the two helps enterprises implement business-driven IT architecture ideas.
I attended the impact conference held by IBM today. I had the honor to meet Ms. Sandy Carter and hear from her about her

In the field of enterprise-class application system development, the Java EE architecture is now universally accepted. Although it has not fully honoured the new appearance of all kinds of beautiful promises, cross-platform, distributed, easy to develop and maintain, but the popularity of Java EE, has been an indisputable fact.
Although the Java EE has been very popular, but technically speaking

2) software reuse is supported. Any two filters can be connected as long as the data suitable for transmitting between two filters is provided;
3) Easy system maintenance and performance enhancement: new filters can be added to existing systems, or old filters can be replaced by improved filters;
4) supports parallel execution: each filter is completed as a separate task, so it can be para

There was a lot of reading on the Internet application architecture talk, but later in practice it was found that the efficiency of using WCF service layer technology to achieve website access was problematic.
My intention is to solve the business logic in the WCF middle tier for each platform invocation, but still bring a lot of trouble, not the best practical solution.
WCF is prominent in enterprise-level development of SOA. However, we should
