Case studies of patterns in software architecture

It contains a ton of examples and covers every aspect of the UML you will need to know to successfully use it on your projects. The book starts out with an introduction to software architecture and object oriented analysis and design with UML. There is then a short chapter on UML notation, a chapter on software development processes, and one on software design and architectural concepts.

Case studies of patterns in software architecture

Written with Hari Kiran. What is software architecture? An interesting and useful definition of architecture is from Grady Booch: The process of creating architecture and later evolving it involves making a series of design decisions. In this article, we present three of those case studies.

These examples show that it is often very hard to perform architecture refactoring because of wrong architecture decisions. What is the meaning of aesthetic design when the flyover creates a traffic mess because it is unusable?

We need to continuous adaptation of the cities and the key elements in the infrastructure; otherwise, it will cause great discomfort to its users. However, refactoring cities and large software is very hard in practice. Dealing with Security Vulnerabilities A large company had a successful networking product that was a cash cow for the company.

The team responsible for the product within the organization was working on adding many new features for the upcoming release. Code-level security vulnerabilities were spread throughout the code base.

If the users could bypass the security layer, the software would become vulnerable to attacks. Since security was the highest priority, the management asked the engineering team to address all the security related concerns discovered so far found in the product.

Since engineering team had spent time only on addressing security concerns and testing the changes, they missed the release deadline and could not realize the promised critical features.

Though code-level security concerns were mostly addressed, since the architecture did not support security, the software continued to be vulnerable. Using Structured Exception Handling A large network monitoring software evolved over a period of more than two decades.

Case Study 1: Dealing with Security Vulnerabilities

Error or Exception Handling EH was a challenge since it was a large application spanning millions of lines of code across numerous components. In a few years, the whole of the application used SEH. As the software evolved, it had to be extended to support other platforms, mainly Unix and later Linux variants.

Also, over a period of time, developers found it difficult to maintain the code that used SEH in older components because they were not familiar with the SEH approach.

These factors caused major maintenance problems for the software. Real-world software often survives to live for many decades.This is a distilled reference guide to the top 5 patterns in software architecture.
