4. IBM Rational Software Development Conference 2008 Session 20036 4 Why Model-Based Development?  Modeling:  Facilitates collaboration between architects and developers  Provides simplified representation of a complex system  Allows engineers to focus on relevant details instead of extraneous implementation details  Facilitates communication of plans to those involved in construction phase  Is a traditional means to reduce engineering risk  Can greatly increase the pace of development!

5. IBM Rational Software Development Conference 2008 Session 20036 5 What is UML (Unified Modeling Language)  Unified Modeling Language  A standard graphical language and meta-model used to Specify, Visualize, Construct, and Document software-intensive systems  Created based on industry-wide experiences regarding modeling and building large and complex software systems  UML includes many diagram types, including:  Class diagrams to describe static structure of the system  What classes are in the system  How the classes are related  What are the class methods and attributes  Sequence, activity, state chart diagrams to describe dynamic system behavior  Class diagrams are often used as input for basic code generation  Generate initial source files with “standard” business logic in the functions

6. IBM Rational Software Development Conference 2008 Session 20036 6 Enabling Business Oriented Developers  So, Model Driven Development is:  Transforming models into code…  Then augmenting that code with business logic  Rational Business Developer Goals:  Allow modelers/architects and “Business Oriented Developers” to collaborate  Implement models on Enterprise Platforms, quickly and efficiently

7. IBM Rational Software Development Conference 2008 Session 20036 7 Model Driven EGL Development and Transformation * DDL = Data Definition Language, can create the DB Relational DB Java Application server JSF DDL* Generators Generate UML JSP RBD TPM Editor Workstation EGL optional CRUD and LIST COBOL

8. IBM Rational Software Development Conference 2008 Session 20036 8 Flow from model to code 1. Create UML Model (using RSA) 2. Add/Edit Transform Parameters (using RBD) 3. Generate EGL Code

9. IBM Rational Software Development Conference 2008 Session 20036 9 Transformation Parameter Editor  Allows users to:  Enables code gen customization  Transform one or more UML elements to EGL  Parameters are available at the level of:  Model  Class  Attribute  Datatype  Examples:  Generate EGL services or EGL Libraries  Generate DDL  UI choices (labels, items in list..)  Data naming, data mapping choices Uncheck this to generate EGL services Choose to generate Web pages, data access functions, and/or data definitions Use this to run the transformations Select the data base

10. IBM Rational Software Development Conference 2008 Session 20036 10 Class-Level Parameters Override defaults that are based on model values

11. IBM Rational Software Development Conference 2008 Session 20036 11 Attribute-Level Parameters

12. IBM Rational Software Development Conference 2008 Session 20036 12 Primitive type elements

13. IBM Rational Software Development Conference 2008 Session 20036 13 “Run Transformation” Sheet Can select all model elements for transforming, or some JSP optional EGL DDL*

14. IBM Rational Software Development Conference 2008 Session 20036 14 Optionally - User Interface Transformation  Produces the JSPs and Page handlers required to drive the CRUD operations  Incorporates the associations between classes by providing navigation  JSF pages have contextual buttons and links based on associations  Detail pages will have buttons that will allow the user to update/modify information  Custom templates and CSS can be applied to any of the default pages that are created  Flexibility to specify read only fields (non-modifiable) in pages

15. IBM Rational Software Development Conference 2008 Session 20036 15 Class Diagram Transformations… Data Definition Transformation dataitem Name CHAR(30) end dataitem Address CHAR(50) end dataitem Phone CHAR(14) end dataitem _Money MONEY(10, 2) end dataitem Integer INT end record Student type sqlRecord {tablenames=[["Student"]], keyItems=[studentId] } studentId Integer {column="Student.studentID"}; name Name {column="Student.name"}; address Address {column="Student.address"}; phoneNumber Phone {column="Student.phoneNumber"}; seminar_seminarId Integer {column="Student.seminar_seminarID"}; end record Seminar type sqlRecord { tablenames=[["Seminar"]], keyItems=[seminarId]} seminarId Integer {column="Seminar.seminarID"}; name Name {column="Seminar.name"}; seminarFees _Money {column="Seminar.seminarFees"}; end

16. IBM Rational Software Development Conference 2008 Session 20036 16 Class Diagram Transformations… Data Access Transformation (Student example for CRUD application) EGL Generated Data Access Functions Function UpdateStudent(updateRecord Student, status StatusRec) try if ( IsValid(updateRecord) ) replace updateRecord noCursor; HandleSuccess(status); end onException (exception SQLException) HandleException(status, exception); end end Update Read Function AddStudent(newRecord Student, status StatusRec) if ( IsValid(newRecord) ) try add newRecord; HandleSuccess(status); onException (exception SQLException) HandleException(status, exception); end else HandleInvalidDBRecord(status); end end Function GetStudent(searchRecord Student inout, status StatusRec) try get searchRecord; if (SysVar.sqlData.sqlCode == 100) HandleDBRecordNotFound(status, "Student"); else HandleSuccess(status); end SysLib.commit(); onException (exception SQLException) HandleException(status, exception); end end Function DeleteStudent(deletionRecord Student, status StatusRec) try delete deletionRecord noCursor; HandleSuccess(status); onException (exception SQLException) HandleException(status, exception); end end Create Delete

17. IBM Rational Software Development Conference 2008 Session 20036 17 Class Diagram Transformations… Data Access Transformation (Student example for CRUD application) Function GetStudentListAll(studentArray Student[] out, status StatusRec) try get studentArray; if (studentArray.getSize() == 0) HandleDBRecordNotFound(status, "Student"); else HandleSuccess(status); end onException (exception SQLException) HandleException(status, exception); end List EGL Generated Data Access Functions
