Click on New Connection button. The following form will appear:. This form contains all ODBC connections added previously. To add a new one, click on New button. The following image shows the ODBC connection manager configuration form:.
In addition, you may have to provide the login information. You can refer to the following official documentation for more information:.
NET framework. It is a set of classes that expose data access services for. NET Framework programmers. NET connection manager allows accessing external data sources, but it uses. NET providers to establish connections. It has the same connection properties such as the provider, server name, authentication, and database name. For additional information about ADO. NET connection manager, you can refer to the following official documentation:. The ADO. NET destination. First of all, it is good to know that ADO.
The SQL Syntax may differ between these connections types, especially when using parameters. Each field has its own data type suitable to the type of data it contains. There are also ODBC drivers for objects which, though they are not database tables, are sufficiently similar that accessing data in the same way is useful.
Examples are spreadsheets, CSV files and columnar reports. Unlike ODBC it encompasses both table-like and non-table-like data such as email messages, web pages, Word documents and file directories. However, it is procedure-oriented rather than object-oriented and is regarded as a rather difficult interface with which to develop access to data sources.
To overcome this, ADO was designed to be an object-oriented layer on top of OLE DB and to provide a simpler and higher-level — though still very powerful — way of working with it.
You are not restricted to some unsatisfactory lowest common denominator. This made an ODBC interface a sine qua non. They were evidently hoping that it would become the data access technology of choice.
However, it eventually became apparent that this was not going to happen for a number of reasons, such as:. In late however, they announced that they would be aligning with ODBC for native relational data access in SQL Server, and encouraged everybody else to do the same. This announcement provoked a storm of protest. People were at a loss to understand why MS was suddenly deprecating a technology that they had spent years getting them to commit to. The driver was released in March On a very basic level those are just different APIs for the different data sources i.
OLE DB is newer and arguably better. The difference in the database behaviour in those cases is what your book refers to. Both are data providers API that your code will use to talk to a data source. Oledb which was introduced in was meant to be a replacement for ODBC introduced in I'm not sure of all the details, but my understanding is that OLE DB and ODBC are two APIs that are available for connecting to various types of databases without having to deal with all the implementation specific details of each.
ODBC works only for relational databases, it can't works with non-relational databases such as Ms Excel files. Where Olebd can do everything. The latter largely relies on SQL.

In days gone by, programs used to be re-written entirely for new or different OS. The process was inefficient. It has since expanded to handle more programming languages. This change in strategy by Microsoft took some off guard. Many stubborn users clung to ODBC for so long, so the move made sense. Also there was the fact that ODBC was expanding. ODBC has expanded its compatibility with the use of drivers, which is a major driving factor in the change of strategy by Microsoft.
This means that as I write this, developers have just two years left to adapt. This table is based off of information by a technical white paper from ftp. That just about sums it up. Did we get something wrong?
