Software Engineering

This is the next phase after the design phase which is used to translate the design into machine-readable form.

This method involves adding operations to a component or removing operations, which are specific to some application domain.

Interrupts are the means of control to transfer a section of code irrespective of the code which is currently executing. Hence, the use of interrupts may cause faults in the program.

In this model, data flow diagrams may be used to show how data is processed at different stages in the system.

Object-oriented programming is concerned with realizing a software design using OOP language.

Defensive programming is an approach to program development whereby programmers assume that there may be undetected faults or inconsistencies in their programs.

Thread testing is a testing strategy, which was devised for testing real-time systems.

In this phase, the design and implementation processes should be organized with the objective of producing fault-free systems.

Process modeling is the phase that concentrates on data transformation so as to achieve information flow necessary to implement a business function.

The term reverse engineering has it origins in the hardware world. A company disassembles a competitive hardware product in an effort to understand its competitor's design and manufacturing secrets.

White box testing, sometimes also called as glass-box testing, is a test case design method that uses the control structure of the procedural design to derive the test cases.

Software validation refers to a different set of activities that ensures that the software that has been built is traceable to customer requirements.

The code generation phase is responsible for translating the design into machine-readable form.

 Fault tolerance is needed in situations where system failure would cause some accident or where a loss of system operation would cause large economic losses.

Software refactoring is the process of factoring the design module where each module factored into the components is more readable and easier to understand.

The client-server approach can be used to implement a repository based system where the repository is provided as a system server.

They provide a means of informing system architects about that class of system.

Global schema defines all the data, which are contained in the distributed database as if it is a centralized system.

Corrective maintenance is concerned with fixing reported errors in the software.

In architectural designs,  the sub-systems making the system and their relationships are identified and documented.

Cursors provide a way for your program to select multiple rows of data from the database and then process each row individually in PL/SQL

Every instantiable object has a default constructor method, which allows a calling program to create new objects of that type.

Database Buffer Cache is an area in memory that holds all the blocks read in from disk for query or modification in System Global Area.

Rounded rectangles represent functions that transform inputs to outputs.

Engineering phase task is required to build one or more representations of the applications.
