These child objects are often dictionary objects themselves, or possibly, arrays of dictionary objects.Nonetheless, let’s dive in to parsing these objects (for the rest of the article, I will assume that you have some experience dealing with dictionary objects; if you need more information on working with dictionary objects, start here).
A Data Set object usually corresponds to a real database table or view, but Data Set is a disconnected view of the database. NET creates a Data Set, there is no need for an active connection to the database, which helps in scalability because the program only has to connect with a database server for microseconds when reading or writing.
This object reads the database and creates an in-memory copy of that part of the database that your program needs.
NET, you can create a wide variety of applications, such as a Console Applications, that displays its output in an MS-DOS-like window, Windows Applications that often displays a form-based interface, Web Applications, Web Services, Mobile Applications etc.
Please don't ask questions on the comments section of the documentation pages because Codeplex doesn't send notifications for them.
Relate Data Table objects to each other with Data Relation objects.
