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!


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


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


Session 20036 7

Model Driven EGL Development and Transformation

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


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


Session 20036 10

Class-Level Parameters

Override defaultsthat are based onmodel values


Session 20036 11

Attribute-Level Parameters


Session 20036 12

Primitive type elements


Session 20036 13

“Run Transformation” Sheet

JSPoptional

EGL

DDL*


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


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


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); endend

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); endend

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); endend

Function DeleteStudent(deletionRecord Student, status StatusRec) try delete deletionRecord noCursor; HandleSuccess(status); onException (exception SQLException) HandleException(status, exception); endend

Create

Delete


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

end
