Maintenance Process

In software design, patterns—that is, structured, named descriptions of good solutions to common problems in context—have become a popular way of recording and transferring problem-solving expertise. The aim of this chapter is to describe how patterns can help in the field of software maintenance. There are two main uses of patterns in software maintenance. The first is to consider the introduction of a design pattern to an existing design. The second approach is to consider patterns for the maintenance process itself. For example, reengineering patterns describe solutions to common problems in the reengineering of a system, considering issues such as how to split the necessary changes into risk-minimizing steps. We discuss the advantages, pitfalls and practicalities of using patterns in both of these ways.

Document Relationships

Native XML databases provide no exception to the problem that data may not be easily contained by any single data storage idiom. Many-to-many relationships, in particular, present a unique problem for documents, as strategies for joining across documents are a potential minefield of software maintenance and performance problems. Automatic denormalization shifts the responsibilty for managing relationships to write-time, making an explicit trade-off for simplicity and speed at runtime. This paper discusses existing strategies for managing relationships across documents and explores design patterns and use cases for performing automatic denormalization and their trade-offs.

Execution Speed

With the mounting demand of web applications, a number of issues allied to its quality have came in existence. In the meadow of web applications, it is very thorny to develop high quality web applications. A design pattern is a general repeatable solution to a generally stirring problem in software design. It should be noted that design pattern is not a finished product that can be directly transformed into source code. Rather design pattern is a depiction or template that describes how to find solution of a problem that can be used in many different situations. Past research has shown that design patterns greatly improved the execution speed of a software application. Design pattern are classified as creational design patterns, structural design pattern, behavioral design pattern, etc. MVC design pattern is very productive for architecting interactive software systems and web applications. This design pattern is partition-independent, because it is expressed in terms of an interactive application running in a single address space. We will design and analyze an algorithm by using MVC approach to improve the performance of web based application. The objective of our study will be to reduce one of the major object oriented features i.e. coupling between model and view segments of web based application. The implementation for the same will be done in by using .NET framework.
