Oracle Applications Using ADO.NET and C#
Rev. 2.0
.NET Training Overview

Oracle is a robust and powerful data storage engine that provides services on all levels of an application infrastructure combining programmer-definable objects and tools, data manipulation tools that are capable of retrieving data from a host of data sources and storing those data in a database, and the capability to automate tasks and run them under developer control.

This comprehensive course is designed to provide programmers an introduction to database programming using Oracle as the database and Microsoft .NET as the programming environment. It will work with either Oracle 9i or 10g, including the free Oracle 10g Express Edition. The course is current to .NET 2.0 and Visual Studio 2005. It consists of two three-day courses that are also available separately. When combined, they can be run in a five-day timeframe.

In the first module programmers will be exposed to database layout and design and actual database programming with the PL/SQL language to create database objects. They will be introduced to various database objects such as SQL Stored Procedures, Functions, Views, Triggers, and much more.

In the second module the course shifts from database programming techniques to application programming techniques communicating with databases using the.NET framework. Programmers will be introduced to ADO.NET, an application-programming interface that allows developers the ability to communicate with many different data sources. Using the various ADO.NET objects, such as Data Readers, Data Adapters, and Data Sets, programmers will learn how to communicate between a database and their applications written in C#. The integration of ADO.NET with XML is discussed and data binding is covered. The course concludes with coverage of data access layers, and students will implement a three-tier application as the culmination of their case-study work in Part 2 of the course.

.NET Training Learning Objectives

  • Gain an understanding of conceptual database design techniques
  • Acquire a working knowledge of database objects and how to implement them using Oracle 9i or 10g.
  • Understand the architecture and main classes of ADO.NET
  • Gain fluency in programming ADO.NET using C#
  • Gain a thorough understanding of the use of disconnected DataSets for building highly scalable applications
  • Acquire a working knowledge of the tight coupling of XML with ADO.NET
  • Implement both Windows Forms and ASP.NET Web Forms front-ends to database applications.
.NET Training Prerequisites

The student should have been exposed to developing applications and have a working knowledge of.NET Framework fundamentals, including building simple Windows Forms and Web Forms applications. The student should also have been exposed to relational databases of some sort.

System Requirements

Course exercises require Visual Studio 2005, the Oracle Data Provider for .NET (ODP.NET), and Oracle 9i or 10g (Express Edition is OK). See the appropriate course Setup Guide for details.

A good minimal hardware profile for this course would have a Pentium 1 GHz or equivalent CPU, 512 MB of RAM, and at least 5 GB of free disk space for operating system, tools installation, and courseware.
