Data Modeling Tools With the development of Universal Modeling Language‚ companies such as Microsoft and fabForce.net have created product to assist developers with designing databases. These tools are called Data Modeling Tools or DMT. Applications can vary from free to thousand of dollars depending on the amount of function ability. Today we will look at Microsoft Visio and fabForce.net DBDesigner 4. Microsoft Visio 2003 is available in a Standard or Professional version and cost around $55

Effective Use Cases Prologue There are still no trusted guides about how to write (or review) use cases‚ even though it is now nearly a decade since use cases have become the "norm" for writing functional requirements for object-oriented software systems‚ and are gaining acceptance for embedded software and business process reengineering work. I can say from firsthand attempts that is very difficult to articulate what makes a use case "good"‚ let alone how to write them so they will come out being

Introduction. In this assignment I am going to explain the following concepts‚ generic strategies‚ alternative directions and alternative methods. Indeed‚ I would like to support these concepts by referring my work to the automobile sector (as a continuing line provided with the Morgan´s example in class). I am going to use the example of General Motors and Ford‚ they are well known and also provide us a long struggling and interesting history. The first part of my assignment gives a theoretical

Mistake Mistake refers to something that is more common. An example is mistaking salt from sugar‚ it is a common mistake and everyone makes it sometimes
