1.1 Developing Database Applications with <strong>RAD</strong> <strong>Studio</strong> <strong>for</strong> <strong>Microsoft</strong> .<strong>NET</strong><br />
1.1 Developing Database Applications with<br />
ADO.<strong>NET</strong><br />
ADO.<strong>NET</strong> presents a coherent programming model <strong>for</strong> exposing data access within the .<strong>NET</strong> Framework. In addition to<br />
supporting MS SQL, Oracle, and OLE DB connection components within the .<strong>NET</strong> Framework, <strong>RAD</strong> <strong>Studio</strong> includes data<br />
providers <strong>for</strong> .<strong>NET</strong> (AdoDbxClient Provider). AdoDbx supports access to MS SQL, Oracle, DB2, and Interbase. AdoDbx<br />
component designers ease the generation and configuration of AdoDbx components.<br />
If you are developing new VCL Forms applications <strong>for</strong> the .<strong>NET</strong> Framework, or you are migrating existing Win32 VCL Forms<br />
applications to the .<strong>NET</strong> Framework, <strong>RAD</strong> <strong>Studio</strong> provides continued support <strong>for</strong> existing Delphi database technologies, such as<br />
dbExpress and dbGo.<br />
This section includes conceptual in<strong>for</strong>mation about how to use <strong>RAD</strong> <strong>Studio</strong> with the ADO.<strong>NET</strong> architecture, as well as the VCL<br />
<strong>for</strong> .<strong>NET</strong> database technologies. and how to build a simple ADO.<strong>NET</strong> project.<br />
Topics<br />
Name Description<br />
AdoDbx Client Overview ( see page 5) The AdoDbx Client implements an ADO.<strong>NET</strong> 2.0 provider <strong>for</strong> all dbExpress<br />
version 4 drivers that implement the newer extended metadata added to<br />
dbExpress 4. All dbExpress drivers shipped with Delphi implement the newer<br />
extended metadata.<br />
AdoDbx Client is an implementation of the ADO.<strong>NET</strong> 2.0 Provider classes.<br />
ADO.<strong>NET</strong> Provider is a set of classes that provide database services <strong>for</strong> .<strong>NET</strong>. It<br />
provides access to relational databases, XML and application data. You can use<br />
it to develop front end database applications as well as multi-tier business<br />
applications.<br />
See .<strong>NET</strong> Framework Developer's Guide ADO.<strong>NET</strong> in the <strong>Microsoft</strong><br />
documentation <strong>for</strong> more in<strong>for</strong>mation.<br />

VCL <strong>for</strong> .<strong>NET</strong> Database <strong>Technologies</strong> ( see page 6) In most cases, the AdoDbxClient Provider provides the best database<br />
connectivity solution <strong>for</strong> your .<strong>NET</strong> applications. However, if you are developing<br />
new VCL Forms applications <strong>for</strong> the .<strong>NET</strong> Framework, or you are migrating<br />
existing Win32 VCL Forms applications to the .<strong>NET</strong> Framework, <strong>RAD</strong> <strong>Studio</strong><br />
provides continued support <strong>for</strong> existing Delphi database technologies.<br />
<strong>RAD</strong> <strong>Studio</strong> provides a migration path from Delphi database technologies running<br />
strictly on Win32 clients to the .<strong>NET</strong> Framework. In addition to being able to build<br />
new database applications using ADO.<strong>NET</strong>, you can migrate existing database<br />
applications to take advantage of .<strong>NET</strong> capabilities. The Delphi database<br />
technologies now... more ( see page 6)<br />
AdoDbx.<strong>NET</strong> Data Types ( see page 11) AdoDbx Client data types map to .<strong>NET</strong> logical types. Dependant upon the<br />
database, AdoDbx Client data types map to native data types. Where applicable,<br />
AdoDbx Client provides:<br />
• Consistent data type mapping<br />
across databases.<br />
• Logical data types mapped to<br />
.<strong>NET</strong> native types.<br />
ADO.<strong>NET</strong> Overview ( see page 14) ADO.<strong>NET</strong> is the .<strong>NET</strong> programming environment <strong>for</strong> building database<br />
applications based on native database <strong>for</strong>mats or XML data. ADO.<strong>NET</strong> is<br />
designed as a back-end data store <strong>for</strong> all <strong>Microsoft</strong> .<strong>NET</strong> programming models,<br />
including Web Forms and Web Services. Use ADO.<strong>NET</strong> to manage data in the<br />
.<strong>NET</strong> Framework.<br />
Note: BDP.<strong>NET</strong> is based on ADO.<strong>NET</strong> 1.1. AdoDbx Client is based on .<strong>NET</strong><br />
2.0.<br />
CodeGear provides tools to simplify rapid ADO.<strong>NET</strong> development using AdoDbx<br />
Client and Borland Data Providers <strong>for</strong> .<strong>NET</strong> (BDP.<strong>NET</strong>). If you are familiar with<br />
rapid application development (<strong>RAD</strong>) and object oriented programming (OOP)<br />
using properties, methods, and events, you will... more ( see page 14)<br />
