Session objective
Attending this session, you will understand how
CodeFluent Entities software factory can be used to
target various architectures
from the same model:
web, smart client, SharePoint, Office or Silverlight
Second session tomorrow:
more focused on code
and specific implementation points for web projects

Challenges faced by developers
Business decision-makers IT •Unclear needs •Changing needs •Increasing expectations •Less money •Less time Business decision-makers •New technologies •Scarce coding talent •Heterogeneous teams•More and more legacy code
Common approaches: focusing on one of the
previous ambition components
TIME
COST
SCOPE
Solution: RAD Tools
Drawbacks: •Constrained features •Prohibitive cost of customization •Dependency Solution: Offshore Drawbacks:
•Weak industrialization and maintenance
•Risk for time-to-market
Solution: CASE Tools
Drawbacks:
•Late on technology innovation •Lack of flexibility
•Proprietary skills and languages
1.
Business entities have longer lifecycles than technology and should be
defined in formats that will
survive technology shifts
and allow supporting
them without reengineering the application
2.
Business rules and process changes need to occur through
short cycles
that
can fit into a lean continuous maintenance scheme
3.
Efficient
coupling
of data, model, and presentation layers including
customized code parts must be
guaranteed by design
4.
Coding
patterns
need to be standardized and their implementation
automated
to ensure maintenance can be performed by
standardized skills
Improving on the CASE tool approach
Costly to customize beyond pre-designed elements
Generated code is standard, human-readable, consistently componentized and
can be extended without any limits Strong dependency on
proprietary programming language with specific skills
Difficult to support latest technology platforms
Business design is structurally separated from target architecture that easily evolve
through specific producers
Historical drawbacks
Solution
Fully integrated into usual development tool, the code is standard as our solution just adds a thin abstraction modeling layer Requires stable definition of
business needs by users
Modeling immediately produces executable components which support a design process friendly to business change
CodeFluent Entities:
Model-driven code generation
CodeFluent Entities Application Life Cycle
Design new models Import existing models Phase 1 Design or Import Phase 2
Model analysis and inference In-memory generation of entity graph, including all modeling concepts (entities, properties, rules, etc.) Phase 3 Generation / Production Generation of technical layers using producers (SQL, .NET object model, web services, etc.) Phase 4 Development Development of customized code usingpartial classes of generated BOM. Phase 4’ Execution Direct use of generated graphic layers(SharePoint, ASP.NET,etc.) Iteration Phase 1 Automated phases

CodeFluent Entities
enables you to develop any
type of application handling
data, while accepting a large
range of development
patterns and generating code
that respects best practices
of .NET development
SDK: Software Development Kit. Through its unique approach to code generation, CodeFluent Entities enables you to immediately produce a ready-to-use SDK for the application you are working on
Code
,
Components
, etc…
CodeFluent provides several
producers
for generating:
Persistence(SQL Server, Oracle Database)
Generate tables, stored procedure, views, constraints, full text search, paging, sorting
Business Object Model
(
BOM
)
C# business layer with transaction handling, serialization, cache, BLOBs management (streaming), paging, sorting, collections, etc.
Web Service for
Office
Web service for an access through MS Access 2007 et MS Excel 2003/2007 with bidirectional synchronizationSmart Client Object
Model (
SCOM
)
Extension of the objet model based on WCF. Dramatically simplifies development of Smart Client (SOA)
Access 2007/2010
WSS 3.0
(*)Excel 2003/2010
(*) Windows SharePoint Services 3.0 (**) Communication based on WCF using the generated SCOM (Smart Client Object Model)

(**)Beyond standard generation,
it’s easy to develop
