What are the characteristics of Object Oriented programming language?
Some key features of the Object Oriented programming are:
Emphasis on data rather than procedure
Programs are divided into entities known as objects
Data Structures are designed such that they characterize objects
Functions that operate on data of an object are tied together in data
Data is hidden and cannot be accessed by external functions
Objects communicate with each other through functions
New data and functions can be easily added whenever necessary
Follows bottom up design in program design
What are the basic Concepts used in the Object-Oriented Programming language?
Data Abstraction and Encapsulation
What is Business Process Execution Language (BPEL)?
BPEL vs. workflow foundation
Role of BPEL
Explain about BPEL Orchestration and Choreography................
Concurrency is the system's ability to act with several requests simultaneously,
such a way that threads don't corrupt the state of objects when they gain
access at the same time.........
To get better results in terms of speed and resources used, it's suggested to
use a cache. We can store in it the results corresponding to the methods'
invocations as key-value pairs: method and arguments as key and return object
Once a user is authenticated and has roles, he or she can work on the
application and perform the actions permitted by an access control list, which
according to the user's roles allows certain operations................
