Case use diagram defines unified modeling language or functionality norms which can create graphical or pictorial overview of the functionality which can define the relationship between actors, goals and dependencies or interrelationship between use cases and their significant functional based direct relationships.

It defines the generic or dominant functions which can easily categorize the norms and functionality between actors. It can easily synchronize or cater to accept the needs and ensure effective business implementation to ensure uses and functionality which can provide a better base for ensuring the norms and tendencies of defining business platform, efficiency, growth and productivity norms.

It includes two business languages which are categorized as follows: unified modeling language and systems modeling language which can depict user based interactions or functional dominations and hence provide functional norms.

Case use diagram highlights the relationships or interlinks between cases and identifies the pattern of relationship between use cases, actors and system boundary boxes. It generally tries to highlight actor generalization which can define overlapping or interchangeament between actors.

It generally defines a solid line or directional arrowhead which can specify directions to identify and develop an interaction essential to coherent or viable resourceful description of the desired behavior norms and parameters.

The relationship between user cases and relationships generally defines the norms and tendencies of normal functionalities. It generally defines four use case relationships which are identified and explained in a business centric portfolio as follows:

*Include: It generally represents direct relationship between cases or user defined norms and helps to establish a chain of interlink functionality related norms.
*Extend: In this type of interaction, one case may extend into another or it may divulge or intrude into other functional requirements.
*Generalizations: A generalized relationship which has set general specifications and norms which categorize specific role-play and functional direction norms between user cases.

To develop, sell, support, install and implement a successful software product a business needs to understand its market, the kind of target audience they want to pursue, identify the opportunity or appropriate utilization of resources, develop and market an appropriate piece of software or data base management system.
