Agile Software Development: Principles, Patterns and Patterns.

This chapter provides a thorough explanation of the concept of programming as a whole. It is claimed that pure programming entails straightforward, clear steps that come together to form a useful program development process. The chapter’s discussion of extreme programming’s common practices offers a suggestion for how a team setup may be used to demonstrate the value of extreme programming. A user of XP may be able to speak for several other XP users or clarify whether quality assurance is available. Another common practice in XP is the user stories which are useful in the planning process of the whole extreme programming process. More so, the chapter mentions the various cycles used as a plan in the XP process. There is an elaboration of the iteration plan, release plan and acceptance tests which show whether the systems provides the specification s provided by the customer. Passing the approval tests v shows the success of an agile development. This chapter also explains about pair programming.

It is stated that pair programming provides an enriched knowledge throughout the whole team of programmer who work at the same station. The simple design of programming is guide by three mantras which provide the roadmap to the developer. These mantras are the basic rules of developing a system, for example, the third rule states that, no toleration of duplication codes. The last practices in XP are refactoring and metaphors. Refactoring is where the XP teams work out to divert the degradation of the codes to ensure that the codes are clean and not duplicated. This chapter concludes with metaphors as an XP practice. Metaphors help in combating the system traffic which may slowdown the networks.

Chapter 7 Review.

This chapter reviews the various methods of conducting the drying out of system codes. Drying of codes provides the roadmap for proper maintenance of the developed system. The chapter also explains the procedures of validations of control filters. It is also stated that, all systems are developed from a certain model figurative. These models validations provide a centralization of the invariants within the system so that the controls of the system s can be effectively operational.

This explains why it is a requirement for users to log in into the systems to access only certain marginalized services of a system. This goes parallel with the active records associations. All system controls are essential in ensuring that the proximity of the services offered by a developed system meets the users’ expectations.

It is also possible to encapsulate the he basic importance of active records in system development. The active records representation in model also helps in creating the relative databases to function normally. The chapter also mentions that it is possible to change language set up and obtain reliable framework architecture. This is possible only if the software can support the DRY codes.

Lastly, the chapter gives an extensive explanation that the model validations can successfully interact with the controllers. The mechanisms explained in this chapter show that partials within the systems allow anyone to reuse the chunks in template forms. The error fields of a model are also important in applying special CSS styles for correct validations.
