.NET Code Synchronization with Class Diagram
 An OOM can be synchronized with C# or VB .NET code
.NET Code Synchronization with Class Diagram
 Changing the .NET code changes the Class Diagram
 Changing the Class Diagram changes the .NET code
Designing .NET Enterprise Applications
 Top-down approach
•
•
•
•
•
•
•
•
Define Requirements
Define Use Cases
Define Sequence Diagrams
Identify classes and operations
Define Business Objects using Class Diagram
Generate Physical Data Model and O/R mapping
Generate database
Generate C# or VB .NET code
Designing .NET Enterprise Applications
 Bottom-up approach
• Reverse engineer an existing database
• Generate a Class Diagram and O/R mapping
• Generate C# or VB .NET code
 Meet-in-the middle approach
• The business objects and database structure are already
defined
• Use Mapping Editor to define the O/R mapping
• Generate C# or VB .NET code
Architecture for Data-Centric .NET Applications
Win From
CAB Layer
Business Logic Layer (BLL)
Domain Model
(POCO classes)
Data Access Layer (DAL)
NHibernate
DAL
ADO.Net DAL
Data-Centric .NET Applications Code
 Domain model
• Business objects for C# 2.0 or VB 2005
 O/R mapping
• NHibernate or ADO .NET
• Factory, Data Access Layer
 Unit test
• NUnit or Team Test
 User interface
• Windows Forms based on Composite Application Block
NHibernate
 NHibernate is a port of Hibernate 2.1 Core for Java to
the .NET Framework. It handles persistence of Plain
Old CLR Object (POCO) to and from an underlying
relational database.
 All Hibernate knowledge and Hibernate documentation
are directly applicable to NHibernate.
 Refer to: www.NHibernate.org.
ADO.NET
 Microsoft ADO.NET is a database-general API. It is an API in
which database vendors write plug-in data providers for their
databases, such as OLE DB/ADO (providers), ODBC (drivers).
SqlClient class
Oracle class
Generic interface
SqlConnection
OracleConnection
IDbConnection
SqlCommand
OracleCommand
IDbCommand
SqlDataReader
OracleDataReader
IDataReader/IDataRecord
SqlTransaction
OracleTransaction
IDbTransaction
SqlParameter
OracleParameter
IDbDataParameter
SqlParameterCollection
OracleParameterCollection
IDataParameterCollection
SqlDataAdapter
OracleDataAdapter
IDbDataAdapter
 Refer to:

NUnit and Team Test
 NUnit is a unit testing framework for all .NET languages.
Initially ported from JUnit, the current production release,
version 2.2, is the fourth major release of this xUnit
based unit testing tool for Microsoft .NET.
 Team Test is a Visual Studio integrated unit testing
framework and tools that enable:
•
•
•
•
Code generation of test method stubs
Running tests within the IDE
Incorporation of test data loaded from a database
Code coverage analysis once the tests have run
Composite Application Block
 Refer to
http://www.gotdotnet.com/codegallery/codegallery.aspx?id=22f72167-af9544ce-a6ca-f2eafbf2653c
Composite Application Block
Preparing .NET Code Generation
 Define O/R mapping
 Add Extended Model Definitions
 Define NHibernate, ADO .NET unit tests, WinForm
parameters in objects’ properties
• Model, classes, attributes, associations
Defining O/R Mapping using Mapping Editor
Add Extended Model Definitions
 Add the following Extended Model Definitions
• NHibernate or ADO .NET
• Unit Test
• Windows Application
Example of NHibernate Parameters
Example of ADO .NET Parameters
Generating Data-Centric .NET Applications Code
 Use Language>Generate C# or VB Code to generate
the entire code
 Compile the generated solution using Visual Studio
2005
 Run unit test using NUnit or Team Test
 Run the Windows application, use users data to test the
persistent objects
 Improve the forms
Integration with PowerBuilder
 PowerBuilder is moving to .NET
 The future version of PowerBuilder can use .NET code
in PowerBuilder applications
 PowerDesigner can help PowerBuilder developers to
better support model-driven development for .NET
Integration with PowerBuilder
 Use PowerDesigner to
• Design requirements
• Design application business objects, business logic and
database
• Support top-down and bottom-up approaches
• Generate database schema and O/R mapping
• Generate .NET code (business objects, O/R mapping)
• Use business objects for business logic implementation
 Use PowerBuilder to
• Develop DataWindows and Forms
• Integrate business objects
PowerDesigner 12.1 New Features
 Visual Studio 2005 plugin
 Support .NET 2.0 (generics, enum, partial class)
 .NET code generation (O/R mapping for ADO .NET and
NHibernate, unit tests for Team Test and NUnit, WinForm)
 Integration with Team Foundation Server
 Better support SQL Server 2005
 Reverse engineer statistics to build IQ column indexes
 Generate load scripts and insert…location scripts for IQ
 Support RepServer 15.0, ASA 10, MobiLink 10, EAServer 6.0
 Support EJB 3.0 persistence management
 Generate CRUD stored procedures
 Show generation links
 Define XML-XML mapping
 Repository proxy for performance improvement
 Update icons
Conclusion
 Using PowerDesigner 12.1 and Model-Driven
Development approach, developers can accelerate
.NET application development and improve the quality.
Thank You!
