DESCRIPTION
Software Development with reuse and for reuse is the foundation of CBSE (Component based software engineering) which allow faster development at lower cost and better usability. A reusable software component works as a plug and play device, which abstract the software complexity and increase performance. This presentation address reuse guidelines based framework (known as .NET Guider) for guidelines based component development for reuse in .NET family and a RV(reuse value) metric. We have demonstrated our approach by designing a binary component as part of development for reuse based on our own .NET Reuse Guider framework. This presentation provides a number reuse analysis and metrics and a prototype (.Net Guider) tool which sits on top of the .NET architecture with built-in software development & reuse knowledge.

Dr.M.Ramachandran, G.Jamnal(2014)
Why software components?
4
Software Industry emerged as Global Market.
Rapid demands for new Softwares in least time and cost.
Plug and Play concept. Maximize reusability to maintain business
profitability.
Software Components
5
Independent and autonomous elements.
Abstract internal complexities(plug & play).
Loose coupled and highly cohesive.
Easy user interfaces(provider & required).
A building block for new product development.
Today’s modern ERP systems are example of Software
Component reuse on big scale.
(Council and George, 2001;Ramachandran ,2008; Zirpins et al. 2014)
Software Component Categories
6
“for reuse” knownas producer reuse.
“with reuse” knownas consumer reuse.
The importance of CBSE was first discovered in NATOconference in 1968.
7
Identifying the common functions.
Dependency on other components.
Optimize design.
Easy use and implementation.
Component decomposition for reuse.
A good Return on Investment (ROI)
Domain analysis for Components
Domain-Software Engineering
8
The success of software component is utterly based on domain knowledge.
1. Exception Handlers: fault tolerance
2. Interface Based Programming : separate
implementation from definitions
3. Delegates: flexibility and strong type function pointers
4. Use Generics “<T>” : avoid boxing/unboxing and
increase performance
9
Proposed guidelines for Component Programming
Proposed guidelines for Component Programming
5. Abstract Classes: alter definitions
6. Façade Class: connect resources- dbconnect i.e
7. Remoting-Object Marshaling : remote objects(rpc)
8. Multi-threading : concurrency management
9. Packaging and deployment: .dlls and .exe

Guidelines framework
11
Architecture of proposed .NET Guider tool
12
Effectiveness of a software component is determined by , number of lines of code required to obtain its functionality in a new software development.
13
Proposing a new Component RV (Reuse value) Metric:
Where:“tngp” = total number of guidelines purposed.“nga”= number of guidelines applied.“cd” = number of Component’s Description.“ngmu” = number of generic method used
GUI: Reusability(%)
