Modeling skills, in particular class modeling and physical data modeling System System classes provide operating-system-specific functionality for your applications, isolating your software from the operating system OS by wrapping OS-specific features, increasing the portability of your application. Analysis skills to identify what needs to be built Architectural and design skills to determine how to implement the classes Modeling skills, in particular class modelingsequence diagrammingand state modeling Collaboration within a layer is allowed. Collaboration can also occur between layers connected by arrows. As you see in Figure 1interface classes may send messages to domain classes but not to persistence classes.

Models, Documents, and Source Code Let's start with understanding the relationships between models, documents, source code, and documentation, something depicted in Figure 1.

From AM's point of view a document is any artifact external to source code whose purpose is to convey information in a persistent manner.

Agile Requirements Core Practices

This is different from the concept of a model, which is an abstraction that describes one or more aspects of a problem or a potential solution addressing a problem. Some models will become documents, or be included as a part of them, although many more will simply be discarded once they have fulfilled their purpose.

Some models will be used to drive the development of source code, although some models may simply be used to drive the development of other models.

Source code is a sequence of instructions, including the comments describing those instructions, for a computer system. Although source code is clearly an abstraction, albeit a detailed one, within the scope of AM it will not be considered a model because I want to distinguish between the two concepts.

Furthermore, for the sake of discussion the term documentation includes both documents and comments in source code. The relationship between models, documents, source code, and documentation.


Why Do People Document? Agile developers recognize that documentation is an intrinsic part of any systemthe creation and maintenance of which is a "necessary evil" to some and an enjoyable task for others, an aspect of software development that can be made agile when you choose to do so.

There are several valid reasons to create documentation: Your project stakeholders require it. The creation of documentation is fundamentally a business decision, you are investing the resources of your project stakeholders in the development of the documentation therefore they should have the final say on whether their money is to be spent that way, not a technical one.

If your project stakeholders request a document from you, perhaps at your suggestion, and understand the trade-offs involved more on this laterthen you must create the document. It is important to note that eXtreme Programming XP is very explicit about documentation being a business decision.

Class Type Architecture: A Strategy for Layering Software Applications

You should create documentation only when your project stakeholders ask you to? Well, my experience is that this isn't preposterous. Your project stakeholders include a wide variety of people, including all of the clients of your system, and therefore they should have a reasonably good idea what they want.

Maintenance developers, or someone representing them if they are not in place yet, will request system overview documentation. Users and their management will likely request user documentation. Operations staff will request operations documentation. Yes, you will need to work closely with them to determine what they actually need, someone is going to have to decide to pay for the development and subsequent maintenance of the documentation, and you may even need to explain the implications of what is being requested, but this is doable.

To define a contract model. Contract models define how your system and an external one interacts with one another, some interactions are bi-directional whereas others are uni-directional, making the interaction s explicitly to everyone involved.

Contract models are often required when an external group controls an information resource that your system requires, such as a database, legacy application or information service.(Results Page 4) View and download transformational theory essays examples.

I originally used the term "class type" because I first started with this approach using object-oriented (OO) technology, although since then have used it for component-based architectures, service oriented architectures (SOAs), and combinations thereof.

Video Setting the rendering options tutorial. First, know that your overall frame rate will be limited by either your CPU or your GPU (your graphics card).

Your CPU may be much more powerful relative to your graphics card, or vice versa.
