Represents a characteristic of an ADO object that is defined by the. ADONET data providers contain classes that represent the providers.
Ado Net Objects Part I
The AdoNet Architecture provides the following two types of class objects.
. Represents a column of data with a common data type. This object provides a connection oriented access to the data records in the database. Is derived from the base DataSet class and then uses information in xsd file to generate a new class.
The DataReader object is an alternative to the DataSet and DataAdapter combination. This is not the case with ADONET which uses a data provider model and the DataSet. This is used to specify action needs to perform on database.
DataAdapter is a class that represents a set of SQL commands and a database connection. ADONET leverages the power of XML to provide disconnected access to data. The SQLDataSetCommand object represents a database query or stored procedure that you use to populate the ADONET DataSet object.
Fundamental Objects of ADONet are DataReader and DataSet. Connection Command DataReader DataAdapter DataSet and DataView are the components of ADONET that are used to perform database operations. ADONET is made of a set of classes that are used for connecting to a database providing access to relational data XML and application data and retrieving results.

Represents a parameter or argument associated with a Command object based on a parameterized query or stored procedure. The DataReader is built as a way to retrieve and examine the rows returned in response to your query as. One is the command object and the other one is the connection object.
Connected and disconnected data access in ADONET. DbCommand and DbConnection Objects. Components are designed for data manipulation and faster data access.
All data providers share ADONET common components. The DataAdapter works as a bridge between a DataSet and a data source to retrieve data. Information from the schema tables columns and so on is generated and compiled into this new DataSet class as a set of first-class objects and properties.
ADONET provides an object-oriented view into the database encapsulating many of the database properties and relationships within ADONET objects. From the above components two components are compulsory. According to Wikipedia ADONET is a data access technology from the MicrosoftNET Framework that provides communication between relational and non-relational systems through a common set of components.
In this article. They are as follows. For example you might use a Command object to execute a SQL UPDATE DELETE INSERT or SELECT statement.
It doesnt allow editing. For example if we want to retrieve a record from an Oracle Database we use the same connection class that we use to tackle the same task with SQL Server. 1 Typed DataSet.
DataSet is a disconnected orient architecture that means there is no need of active connections during work with datasets and it is a collection of DataTables and relations between tables. It is used to establish a connection to a specific data source. The connection objects helps to identify database server database name user name and password.
It can provide fast and forward-only data access. Up to 5 cash back The Command object is the heart of data processing with ADONET. These objects are suitable for read-only access such as populating a list and then breaking the connection.
Some of the common components are DataSet DataView and DataViewManager. They are the data provider objects such as Connection Command DataAdapter and DataReader. DataSet can be used in disconnected connection with DB.
Each DataTable object has a Columns collection which is a container for DataColumn objects. It is used to. ADONET is a set of computer software components that programmers can use to access data and data services from a database.
To interact with database one must have a connection to it. The DataSet uses XML to store and transfer data between the applications and the data provider. DataReader is used to read the read only data from a database.
They are as follows. Heres a preview of the seven main objects in the ADONET architecture. ADONET - Connected and disconnected data access in ADONET - This object requires exclusive use of the connection object.
ADONET provides consistent access to data sources such as SQL Server and XML and to data sources exposed through OLE DB and ODBC. Each Field object corresponds to a column in the Recordset. In ADONET DataTable objects are used to represent the tables in a DataSet object.
A DataSet is a set of DataTable objects. The DataAdapter takes the results of a database query from a Command object and pushes them into a DataSet. They execute SQL statements and connect to a database.
It is used to read data from data source. What are the ADO Net DataAdapter objects. Dataset is a in-memory representation of database.
To access the actual values stored in a DataTable object use the objects Rows collection which contains a series of. A DataTable represents a. Shared by both the System.
Typically the Command object wraps a SQL statement or a call to a stored procedure. The ADONET Architecture is comprising of 6 important components. ADONET separates data access from data manipulation.
ADONET includes many objects to work with database. A DataColumn object corresponds to a column in a table. It is used to execute queries to perform database operations.
ADONET has two main components that are used for accessing and manipulating data. The architecture of ADONET. Data-sharing consumer applications can use ADONET to connect to these data sources and retrieve handle and update the data that they contain.
These components represent the data. The DbDataReader is a base class for all DataReader objects. Further and in many ways most important the ADONET objects encapsulate and hide.
It populates a DataSet and resolves updates with the data source. However ADONET providers that dont represent databases may use their. The primary objects are Connection Object.
Up to 5 cash back The goal of ADONET is to provide a bridge between your objects in ASPNET and your back-end database. ADONET is the data access component for the NET Framework.
