Tabular Data Stream is an application-level protocol used to transfer data between a server and a client. TDS sets the type of messages that can be sent in packets between computers, as well as the order in which those can be sent. TDS protocol was designed by Sybase Inc. for the Sybase SQL Server, and later developed by Microsoft for use in the Microsoft SQL server.

A class library is a collection of prewritten, coded templates which can be utilized by programmers in the development of an application. Rather than having to code those individual instructions manually, the programmer instead specifies which classes will be utilized and creates an instant for objects they will be using from the class library. Utilizing class libraries not only speeds up programming, but ensure that tested procedures are performed accurately and in a standard way across applications.

ADO.NET is part of Microsoft’s .NET framework, and so it requires a Windows server to host. However, there are some open-source projects, like Mono, that are attempting to implement the .NET framework to other platforms. Using these programs, it may be possible to utilize ADO.NET on a non-Windows server, but you should check with your host to ensure compatibility.

Yes. ADO.NET can store (pool) a group of active objects in memory to be called upon as needed. Doing so allows ADO.NET to reduce the number of objects that need to be created and initialized, minimizing the use of system resources and performance.

The ADO.NET Framework utilizes both Connection Oriented Data Access Architecture and Disconnected Data Access Architecture. ADO.NET utilizes a DataSet class to allow the application to store and hold multiple tables in memory at the same time, rather than needing to continuously access the database. In order to get data into the DataSet, the application uses a DataAdapter to pull information from a DataReader (the connected access) and provide it to the DataSet (the disconnected access). Because the database information is being stored in the DataSet, the DataReader only needs to access it once, very quickly, and then it can disconnect from the database. This allows the program to conserve system resources and enhances the security of the database.

If you’re thinking of utilizing ADO.NET, you should first have a clear understanding of relational database concepts, including table, row, column, primary keys, foreign keys, constraints, and views. You should be experienced in data query and modification, and comfortable using the SELECT, INSERT, UPDATE, and DELETE commands. A general familiarity with XML documents is recommended, as well as experience with Visual Basic. Previous experience building user interfaces will also be helpful. If you have all that, and you feel ready to start programming, there are plenty of resources available online to help you get started.

Classic ADO utilized only connection-oriented data access. The only in-memory store of data it supported was the recordset, which is used to hold a set of records from a single database table. ADO.NET utilizes DataSets to store data from multiple tables into memory, allowing it to utilize disconnected oriented data access.

ADO.NET provides programmers with a number of benefits, including scalability, data source independences, interoperability, strongly-typed programming fields, and improved performance over other database connection classes.

ADO.NET allows you to specify Pessimistic or Optimistic locking. Pessimistic locking completely locks a data file while one user is updating it. Other users can view the data, but they cannot make any changes. Optimistic locking allows multiple users to open and update the same record simultaneously. In this case, the data is only locked briefly while an update is actually being applied.

ADO.NET supports clustered and non-clustered indexes. In clustered indexes, the physical rows in a data table are re-ordered to match the order they are listed in the index key. In this case, a table can only contain one clustered index, as everything has to remain in a single order. In a non-clustered index, the physical order does not have to match the key values, and a table can contain multiple non-clustered indexes.

ADO.NET utilizes command objects to execute queries against a database. Each command object executes a single query, performing an action such as creating, retrieving, adding, updating, or deleting a record.

The easiest way to do this is to back up the database from your source server as an SQL script. On the new server, you can then execute the SQL script to recreate the database.
