Versioning is done only on assemblies with strong names
Each assembly has a version number. As such, two assemblies that differ by version number are considered by the runtime to be completely different assemblies. This version number is physically represented as a four-part number with the following format lt major version gt . lt minor version gt . lt build number gt . lt revision gt For example, version 1.2.200.0 indicates 1 as the major version, 2 as the minor version, 200 as the build number, and 0 as the revision number. The version number is...
Figure 62
A typical data flow diagram, which documents the data interactions of a system and inventory system. Within this high-level diagram, the retail sales process might be represented by a single entity. A lower-level DFD might focus on a specific process within a complex system. For instance, it is possible for a DFD to display data flow within the retail sales process only. This low-level diagram could contain a dozen or so entities, but is definitely more detailed than the high-level diagram....
Creating ORM Diagrams in Visio
As we discussed in Chapter 1, Microsoft Visio for Enterprise Architects is a full-featured diagramming tool that has many applications outside of the application design arena. The tool contains hundreds of symbols and icons that can be used to create complex diagrams and graphics. Of course, because it is included with the Enterprise Architect edition of Visual Studio .NET, it contains dozens of icons and templates for designing software applications and databases as well. Chapter 2...

User Interface Conceptual Design
Many would believe that thinking about user interface design during the conceptual design stage might be a little premature but when you think about it, user interface designers have everything they need at this stage to get started on a basic user interface design The users of the application have been defined during the user requirements stage. The required functionality of the application has been defined during the business requirements stage. An idea of the target platform and operating...
From The Classroom Kgt
Understanding the Five Rules of Normalization One of the early concepts of database development, which predates even the existence and widespread use of relational databases, is the concept of normalization. Normalization is the process of organizing a database according to certain rules. These rules exist to ensure that the database is unambiguous and operates as intended efficiently and without data loss. The ORM process does a good job ensuring that ambiguity and redundancy are removed from...
The WindowsPrincipal is the most common principal used It is used for Windows
The GenericPrincipal and GenericIdentity are used for authorization independent of Windows NT and Windows 2000 domain. A classic example of this would be an application that requests user name and password for authorization, and the information is checked against a database or XML file. The following code shows how to use the GenericPrincipal is very similar to the WindowsPrincipal object. GenericIdentity Myldentity new String MyStringArray new GenericPrincipal MyIdentity, MyStringArray...
Creating a Test Plan
The test plan describes the strategy used to organize, and manage the project's testing activities. It identifies testing objectives, methodologies and tools, expected results, responsibilities, and resource requirements. A test plan ensures that the testing process will be conducted in a thorough and organized manner and will enable the team to determine the stability of the solution. The test plan breaks the testing process into different elements, including unit testing, database testing,...
