What is a domain?

• Domain is a field of study that defines a set of common

requirements terminology and functionality or any

software program constructed to solve a problem in that

field.

INTRODUCTION-DSM

• Domain-specific modelling (DSM) is a higher level of CASE.

• It consist of a way to model data structures and logic in Domain concepts.

• It independent from programming languages and thus also syntax details.

INTRODUCTION-DSM c o n t …

• The final source code in a desired programming language

is derived automatically

• DSM is a high abstraction models by using specific

language generators.

• The basis for DSM is Language Engineering allowing to

define and to use various Domain Specific Languages.

LITERATURE SURVEY

• Most importantly, making the models is much faster than

writing the code by hand.

• In Industrial experiences at leading-edge players like Nokia

and NASA have consistently shown development becoming

five to ten times faster

PROBLEM DEFINITION

• Software development concept consist of a huge importantand bizarre part is code writing

• The coding part will be implemented using programmersand it will take lots of time and cost for developing asoftware.

• The coding will be done by using software programmers byspending the major time of their session and efforts.

PROBLEM DEFINITION

• Domain Specific modeling is replacing the all aboveworks, so DSM tools undertaking the coding parts as itsown properties.

• That is the coding parts as its own properties, it reduces thetime and expenses of developing a software the manualprocessing.

EXISTING

• The unified modeling language (UML) is a general-purposemodeling language for software Intensive system that is designedto support mostly object oriented programming.

• Experience of using UML as a modelling language is widespreadand so using UML to express what is required in a system andgenerating code from that is acceptable for many organizations.

METHODOLOGY

•DSM (Domain Specific Modeling)

•MetaEdit+ (Tool)

Domain-specific modelling

• Domain-specific modeling is a specific type of software

engineering methodology or modeling language for designing

and developing.

• A modeling language is any artificial language that can be

used to express information or knowledge or systems in a

structure that is defined by a consistent set of rules.

CONT….

• Domain-specific languages are a

“natural extension to code

libraries and frameworks”, making

their use faster, easier and more

consistent..

Domain-specific modelling Benefits

• Industrial experiences from domain-specific methods

consistently show major improvements in productivity,

time-to-market responsiveness.

• DSM Tools sped up the programming into many folds.

• DSM Increase the Quality and Hiding the complexity.

Benefits

• DSM is high-level languages specific to a particular application or

set of tasks.

• DSM are closer to the problem domain and concepts.

• Domain-Specific Modelling allows faster development, based on

models of the product rather than on models of the code.

• It can shows 5-10 times faster than current practices.

DSM - Benefits

DSM – Domain’s

DSM – Tool (MetaEdit+)

• MetaEdit+ is an environment for creating and

using Domain-Specific Modeling languages.

• MetaEdit+ is an integrated, repository-based tool set for

creating and using modeling languages and code

generators.

• MetaEdit+ provides the tool support for different modeling

languages by configuring the generic tool set with

metamodels

Tools-MetaEdit+

• For defining metamodels, MetaEdit+ employs the GOPPRR

metamodeling language.

• Several modelling languages can be used simultaneously and

there can be links and references between different

languages.uages and code generators.

Architecture-MetaEdit+

MetaEdit+ is an

integrated,

repository-based

tool set for creating

and using modeling

languages and code

generators

MetaEdit+-Best Choice:

• Support several integrated languages

• Graphical and form-based metamodeling: no

programming needed

• Integrated metamodeling and modeling

• Models update automatically when a metamodel

changes

Cont..• Multiple concurrent metamodels

• WYSIWYG symbol editor for defining representations for

metamodel elements

• SVG and bitmap importing for symbols

• Code generation using templates and multiple streams and

debugger

• Generate any language and output format

• Metamodel import and export XML

• Large metamodel library available

• Generators and metamodels integrated

EXPERIMENTATION

• DSM makes a difference the level of concept forcurrent programming languages by specifying thesolution directly using problem domain concepts.

• The final products are than generated from these highlevel specification.

SEQUENTIAL PROCESS

• MetaEdit+ Workbench allows you to build your own modeling

tool without having to write a single line of code.

CODE GENRATOR

Generator translates the models into the required output. The

code and model combined which produce generator

(code + model=generator)

• Simple text Model checking

• Documentation Xml

• Flow machine State machine

CODE GENERATOR cont….

IMPLEMENTAION

• Implementation is the stage of the project when the

theoretical design is turned out into a working system

• MetaEdit+, which is a fully functional CASE

environment with wide modelling language support,

documentation reports and code generators.

• This manual provides information about MetaEdit+

Implementation

IMPLEMENTAION CONCEPT

IMPLEMENTATION FOR DIGITAL WATCH

Drawbacks of Existing System

• User interface is not very easy to use. - Rational and UML is to support the design of the data to support poor on the links between different model also cannot support. Therefor from the user to not convenient

• The Existing System will not support the same product in the different directions to do the analysis, design and development.

Features of Proposed System– MetaEdit+

• Domain Specific Modelling (MetaEdit+) deals with the specialty of less time consumption low cost and fast computing.

• In a development of a software consist of lot of procedure and designing procedure.

• Manual programming was seen as too costly, time – consuming, and leading.

• The Company was seeking an efficient way to capture and implement .

PRINCIPLE OF DIGITAL WATCH

• Domain-specific modeling (DSM) often also includes the idea

of code generation-automating the creation of executable source

code directly from the domain-specific language models

C O N T ….

ARCHITECTURE OF DIGITAL WATCH

• Watch architecture

consist of three parts:

a modeling language,

a code generator and

a domain framework.

DEVELOPING GENERATOR

• MetaEdit+ delivers your language and generator immediately to

the developers of your team.

• The created development tool support your modeling language,

generates your code the way you want, and produces documents.

• MetaEdit+ provides the necessary functionality for creating and

debugging generation script, and it guides the expert to access the

concepts in the metamodel.

RESULT

• MetaEdit+ delivers your language and generator immediately to thedevelopers of your team.

• The created development tool support your modeling language,generates your code the way you want, and produces documents.

• MetaEdit+ provides the necessary functionality for creating anddebugging generation script, and it guides the expert to access theconcepts in the metamodel

Result Expected

RESULT

TOOL COMPARISON

• MetaEdit+ is a tool with a proprietary metamodelling paradigm andgenerator definition language.

• Since MetaEdit+ tool is not tied to UML in any way, it offers veryflexible possibilities for DSML definition.

• The definition of DSML does not require any manual coding and thecode generation support is very good.
