1. An Automated Object Relational Mapper

2. What is NetTiers  Discovered Indirectly While Using Mojo  NetTiers = Open Source = FREE  Backed by CodeSmith Template Driven Source Code Generator  CodeSmith = Commercial ($99 - older versions are free, have $10 off coupon  http://www.codesmithtools.com/ http://www.codesmithtools.com/  Basically is a Complex CodeSmith Template That Auto Generates N-Tier Web Applications w/ relevant CRUD, validation, unit-testing, deeploading (more later), etc.

3. CodeSmith Template Generators  NetTiers  NHibernate  PLINQO  Wilson’s ORMapper  APOSA  See more at http://www.codesmithtools.com/features/ frameworks.aspx http://www.codesmithtools.com/features/ frameworks.aspx

4. NetTiers Features  Generates a pre-compiled solution along with separate projects and framework tiers for your application  Creates Entities/Classes Based On Your Defined DB Schema - http://nettiers.com/database.ashx http://nettiers.com/database.ashx  Partial/Concrete Classes  nUnit testing  Very robust data API  Much more

5. Example Sites  DSA Site Inventory - https://wsnet.colostate.edu/CWIS463/ds a-sites/ https://wsnet.colostate.edu/CWIS463/ds a-sites/  Diversity Library System - http://wsnetdev.colostate.edu/CWIS165/ home http://wsnetdev.colostate.edu/CWIS165/ home  RDS Exam Intake System - http://wsnet.colostate.edu/cwis248/exam s/ http://wsnet.colostate.edu/cwis248/exam s/

6. Observations  Has a bit of a learning curve (eg. Took me a few days to understand how to make url routing work in the framework) MOST IMPORTANT – Spend all the time you need to get your DB schema right before generating  Know what you’re doing when regenerating solution after a db schema change  I plan on using it for most any medium to large project (at least when doing web forms). Is overkill for small projects.  Guessing it made a (minimum) 20 hour job take 2 hours for the DSA site inventory  Lot more to learn – only used a month or two

7. Let’s Build a Site  Db Schema – Nail This Down  Download/Install CodeSmith & NetTiers  Open the NetTiers template file (.cst)  Mandatory Fields: SourceDB (YOUR SQL DB INSTANCE) MappingFile OutputDirectory (LOCATION OF PROJECT) RootNameSpace (YOUR_SITE) http://nettiers.com/GettingStarted.ashx#CB:_AB _Getting_Started_-_Required_Properties_0 http://nettiers.com/GettingStarted.ashx#CB:_AB _Getting_Started_-_Required_Properties_0

8. Let’s Build a Site  Recommended Fields: SourceTables IncludeComponentLayer - ServiceLayer and DomainModel (your business layer) IncludedDatabaseFeatures – SQLServer2005 IncludeUnitTest - True DataSourceEnableTransactionDefault – False IncludeAtlasLibrary – (learned about today) IncludeAtlasToolkit

9. Let’s Build a Site  Post Generation: Open VS and convert solution to rely on.net 4.0 if desired Move UI files (App_Themes, Common, MasterPage, SiteMap) over Set Default Page to Admin/Default.aspx Run solution Demo Declarative Stuff Demo Code Behind Stuff

10. To Demo  Declarative Stuff Add Exam Request (note ddls generated from foreign keys) Search Export Edit  UserControls - DRY  Code-Behind Using the ServiceLayer API http://nettiers.com/ComponentLayer.ashx

11. Validation – ExamRequestsBase.generated  ///  /// Assigns validation rules to this object based on model definition. This file is overwritten upon regeneration!  ///  /// This method overrides the base class to add schema related validation.  protected override void AddValidationRules()  {  //Validation rules based on database schema.  ValidationRules.AddRule( CommonRules.NotNull,  new ValidationRuleArgs("CourseNumber", "Course Number"));  ValidationRules.AddRule( CommonRules.StringMaxLength,  new CommonRules.MaxLengthRuleArgs("CourseNumber", "Course Number", 256));  ValidationRules.AddRule( CommonRules.NotNull,  new ValidationRuleArgs("SectionNumber", "Section Number"));  ValidationRules.AddRule( CommonRules.StringMaxLength,  new CommonRules.MaxLengthRuleArgs("SectionNumber", "Section Number", 256));  ValidationRules.AddRule( CommonRules.StringMaxLength,  new CommonRules.MaxLengthRuleArgs("ExamDelivery", "Exam Delivery", 256));  ValidationRules.AddRule( CommonRules.StringMaxLength,  new CommonRules.MaxLengthRuleArgs("ExamReturn", "Exam Return", 256));  ValidationRules.AddRule( CommonRules.StringMaxLength,  new CommonRules.MaxLengthRuleArgs("TimeAllowed", "Time Allowed", 100));  }

12. Validation – EntityRequests.cs  Partial Class File Not Overwritten. More Info On Validation - http://nettiers.com/EntityLayer.ashx  /**/  ///  /// Validates the exam date.  ///  /// The target.  /// The e.  ///  private bool ValidateExamDate(object target, Validation.ValidationRuleArgs e)  {  if ((this.ExamDate ?? DateTime.MinValue) < DateTime.Today)  {  e.Description = "The exam date must not be in the past.";  return false;  }  return true;  }

13. Going Forward  Add more unit tests  Add Elmah library to effectively handle application errors http://code.google.com/p/elmah/  Add Sandcastle Documentation Compiler to tie comments together http://sandcastle.codeplex.com/  CSS-based pretty forms – pForm  Blueprint CSS stylesheet resets  OWASP, if necessary?
