CodeSmith & .netTiers Using Code Generation to boost productivity Robert Hinojosa [email protected] Agenda • • • • What is Code Generation? What is CodeSmith? What is .netTiers? How can .netTiers help me? What is Code Generation • Software creation • Can be fun and challenging • …but also repetitive and monotonous • Repetition & monotony leads to bugs • Code generation is not a new concept • With most tools you don’t control the output • Often viewed as a “Black Box” solution • Ex, data layer created (but it is not your code) • CodeSmith 4.0 • Not a “Black Box” solution • Template driven code generation (it is your code) • Use existing templates or write new ones The value of .netTiers • The cost of creating a home grown framework • Design, Development, Test, Release • Easily runs between $50 - $300/hour • CodeSmith • .netTiers 2.0: Free open source templates with thriving community • CodeSmith 4.0 Professional: $399 • For you, FREE! • Equivalent to 3-6 hours of development • Real value you can measure • Dramatically reduces time to market & cost • Quickly pays for itself Using CodeSmith 4.0 What is .netTiers .netTiers is a library of Codesmith templates that builds object-relational mapping for an existing database. • Creates objects and domain based on the relationships in your database. • Creates separate Logical layers Entity, DAL, Business, Web, Forms, WebService • Creates stored procedures or parameterized SQL for data access layer. • Creates Asp.Net 2.0 admin user controls. • Creates code which is fully XML commented .netTiers Advantages • 100% Open Source, Template Driven • Reduces development time • Reduces maintenance time • All applications have a consistent domain model, with standard code • Making changes / updates by another team member easier • Promotes reuse • Data Access completely separated from user interface • Promotes Enterprise Standards utilizing Microsoft P & P Enterprise Library • Easier Application Integration Domain Model vs DataSet • Predictable behavior • Compare the following methods • public Customer GetByCustomerId(int id); • public DataSet GetByCustomerId(int id); • Promotes loose coupling of presentation and domain logic • Easier to document • Intellisense in Visual Studio • Less memory intensive Using .netTiers Data API • Support for basic CRUD: Update, Delete, Insert, Find, Paged, Custom Sprocs, GetBy (PK, IX, FK, M:M) • Support for queries using: • Primary Key • Foreign keys • Indexes • Many-Many join relationships Data API • Transaction Support • API Plumbing generated from Your own Stored Procedures EX. _TableName_MyMethodName • Support for deep object graph loading/saving • Use stored procedures or xml embedded parameterized SQL Sample Method Calls //All Providers kept within DataRepository class EmployeeCollection employees = DataRepository.EmployeeProvider.GetAll(); //When using primary key, single object is returned Employee emp = DataRepository.EmployeeProvider.GetByEmployeeId(4); Employee newEmployee = new Employee(); newEmployee.FirstName = “John”; newEmployee.LastName = “Doe”; … //when inserting the primary key value is set for the object bool success = DataRepository.EmployeeProvider.Insert(newEmployee); //inserting collection EmployeeCollection ec = new EmployeeCollection(); Employee e1 = new Employee(); … ec.Add(e1); bool success = DataRepository.EmployeeProvider.Insert(ec); Using .netTiers API Conclusion/ Q&A • .netTiers 2.0 • Proven Pattern Based Framework Generation • CodeSmith 4.0 • Most powerful code generation tool available • Reduces time spent writing trivial code • Be more productive • Template driven means it’s still your code • Saves you time and money Learn more • www.codesmithtools.com • Download free 30 day trial Contact Us • [email protected] • +1 972 407 0688
