We basically process the shape of each individual letter in a word at the same time, and therefore determine the word itself. We then derive the semantics of the word using "back up" files in the brain.

By Identifing it by knowing language or knowledge

The object diagram should use , When relationship of objects are getting at the runtime and system is very complex

The technique of identifying objects on the basis of their properties collection or by giving description in the form of string arguments is known as Descriptive Programming. It is mainly used in the...

Unified Modeling Language (UML) is a standard language for writing software blueprints.
The UML may be used to visulize, specity, consrtuct and document of a software-intensive system.

Using the Unified Modeling Language will result in lower overall costs, more reliable and efficient software, and a better relationship with parties involved. Software documented with UML can be m...

Composition is the strongest form of association - not a "Weak has a " as said above...

First let me say that aggregation is not composition or viseversa.  The OOD concept is "Association" and there are two types.  Both are "Has a" relationships.  ...

Use case represent the function which perform by software system and it is initialised by actor.

use case diagrams mainly used to represent the functionality of a system in terms of actors and use cases.

This comes under OOAD :Steps involved :-----------------------------------------------------1. Identifying the Actors2. Identifying Individual Usecases ( Draw usecase diagrams, Which includes Actor pa...

By using Use Case Driven Object Modeling with UML.

Class diagram contains three parts. First part represents the class name, second part represents the attributes of the class, third part represents the functions of the class.

Furthermore, an API is often a finished, working component which is readily used (maybe with some minor additions). Frameworks are in no instance ready out-of-the-box and aim to take care some of the ...

API is a set of classes written for a desired functionality..For example JDBC API provides the functionality to connecting databases in java..whereas framework is also a set ot classes but the purpose...

No, UML was not developed by Rational Software(was developed by the Object Management Group), although some of the people on the OMG committee do/did work for RS (now owned by IBM, in the Rational division).

UML is based on the work of Grady Booch, Ivar Jacobson, and James Rumbaugh.  The UML standards were later developed by the Object Management Group (OMG).

Some object-oriented languages such as C++ and Ada support the concept of parametrized classes. C++ calls this facility “templates”, and Ada calls it “generics”; UML uses the C++ term. New ...

UML can be used to model the whole system visually independently of the platform language. This applies to the very high level architecture (Component diagrams, Use-Case diagrams, State diagrams, etc....

To develop Use Cases and to Provide users with a ready-to-use, expressive visual modeling.

Sequence Diagrams (Message Sequence Charts) and Collaboration diagrams have a one to one relationship. Given a MSC you can easily convert it into a Collab. diag. and vice versa. However, the form in w...

Aggregation: Child object refrence exists even after the Parent object refrence set to null.In Some Scenarios child refrence is required even after the Parent object refrence set to nul...

Aggregation: when one class owns but shares a reference to objects of another class. symbol: empty diamond arrow.

Composition: when one class contains objects of another class. symbol: filled diamond arrow.
