Exception Management in WCF

2010-09-09T17:20:00.000+05:30

Exception Management in WCF In WCF applications, service methods communicate processing error information using SOAP fault messages. SOAP faults are message types that are included in the metadata for a service operation and, therefore, create a fault contract that clients can use to make their operation more interactive. In addition, because SOAP faults are expressed to clients in XML form,

Asp.Net State Management

2010-08-08T20:59:00.000+05:30

ASP.NET State Management State management is the process by which you maintain state and page information over multiple requests for the same or different pages. Pages are destroyed and re-created with each round trip to the server; therefore, page information will not exist beyond the life cycle of a single page. ASP.NET provides multiple ways to maintain state between server round trips

Aggregation

2010-08-06T12:10:00.000+05:30

Aggregation (“has a” relationship): Aggregation occurs when a class is a collection or container of other classes, but where the contained classes do not have a strong life cycle dependency on the container; essentially, if the container is destroyed, its contents are not. Example: Room has a table and the table can exist without the room. The table can have meaning without the room also.

Composition

2010-08-06T12:04:00.000+05:30

Composition ("is part of"): Composition is also known as a 'is a part of' relationship because the member object is a part of the containing class and the member object cannot survive or exist outside the enclosing or containing class or doesn’t have a meaning after the lifetime of the enclosing object. Example: If we were going to model a car, it would make sense to say that an engine is

Generalization

2010-08-06T11:57:00.000+05:30

Generalization (“is a” relationship): The generalization relationship indicates that one of the two related classes is considered to be a more general form of the other. (Or) Many similar existing objects are combined to form a superclass to do the job of its subclass, and then it is known as Generalization. The generalization relationship is also known as the Inheritance or parent/child
