USING ADO .NET

Evolution Of ADO .NET
 Database is required by organization to retrieve,
manipulate and update huge amount of data.
 Data Access Model (DAO)
 First model used for connectivity.
 This model followed by VB and mainly by Jet Engine Database.
 Problem:
 Performance not so good.
 Remote Data Object (RDO)
 Introduced for remote database like Oracle and SQL Server.

 ActiveX Data Object (ADO)
 Specially designed for Client-Server architecture.
 Good for Relational and Non-Relational databases.
 Problem:
 Connected Data Access, which leads to Security, Performance issue
and Network Traffic.
 ADO .NET
 Eliminated problems found with earlier models.
 Widely used access technology for connectivity.
 Fulfil needs of developer and built upon .NET framework.
 Used by application to communicate with database for all
database operations.

 Main Features:
 Disconnected architecture.
 Integration with XML.
 Data from multiple data stores.
 Optimized performance for connecting with database.
 Uniform database access technology
 Common type system
 Design pattern
 Exception handling

ADO .NET Description
 Data access component for .NET Framework.
 Enable communication with Database as well as other
Structures like Array, Collection etc.
 Supports data centric application development and use
disconnected architecture for accessing data.
 Support all types of databases for retrieving, accessing and
updating data.
 ADO.NET establish connection with data source, send
query, update statement of data source and return result.
 Results either processed directly or stored in data set
object.

Features of ADO .NET
 Disconnected data architecture
 Connection established only when required.
 Avoid wastage of Resource & improve performance.
 Scalability
 Work with dataset without connecting with database.
 Can meet increasing demands of database users more efficiently.
 Interoperability
 Data transfer is achieved by using XML format.
 XML is standard format for exchanging data in different application.
 Increase safety of code and reduce compilation errors.
 Separation of data logic and interface.
 Enables integration of data from multiple heterogeneous data sources.
 Uses COM+ based connection pooling.

Data Provider
 SQL Server Data Provider
 Connect with Microsoft SQL Server.
 System.Data.SQLClient namespace is used.
 OLEDB Data Provider
 Connect with OLEDB data source like Oracle, Jet and SQL.
 System.Data.OLEDB namespace is used.
 ODBC Data Provider
 Connect with ODBC data sources.
 System.Data.ODBC namespace is used.
 Oracle Data Provider
 Connect with Oracle data sources.
 System.Data.OracleClient namespace is used.
