PHASES OF THE PROGRAMMING PROCESS

PHASE 1-Definition of the problem

It is the phase in which the problem or task is clearly defined and understood.

PHASE 2-Analysis

To analyze point by point the problem or task that is presented, think about the operations necessary to solve it, the types of data to handle and the relationship with everyday life situations.

IMPUT
Data to be entered to solve the problem

PROCESS
Procedures where the input data is used to solve the problem

OUTPUT
The solution of the problem

PHASE 3-Design

Consists in develop the procedure (step by step) to solve the problem.

ALGORITHM
The algorithm can be defined as a set of logically ordered steps to carry out a given task or that describe the solution of a problem.

TYPES

Sequential
The steps are executed or de scribed from beginning to end without jumps

Conditional
They involve making decisions in some of the steps due to conditions or questions that lead to answering true or false, or to follow one path or another.

Cyclical
Are those where there are actions or steps that are repeated while or until a condition is met.

CHARACTERISTICS

-Have a beginning and an end.

-Have a finite number of steps.

-The steps must be logically ordered.

FLOW DIAGRAM
The flow diagram is the graphical representation of an algorithm, it is one of the pro gramming tools that allows to visualize in a general way the development of the solution of a problem.

Blocks or template are used to the construccion

DESKTOP TEST
It consists of giving value to the variables in the flow chart and checking if the result obtained is as expected.

PHASE 4-Coding

It is the translation of the algorithm or flow chart into a programming language according to its grammar rules or syntax.

PHASE-8 Documentation

It is very imortant phase, since it generates both the technical manuals and the user manual and help.

PHASE-7 Maintenance of the program

The peogram implemented in the work area has to be periodically reviewed with possibility of removing or adding instructions that are adapted to the needs of the system and make it more effective.

PHASE-6 Interpretationof the program

Here, the designed and developed program is installed in the system to fulfill the task entrusted, it is tested and run several times, results are controlled, and its effectiveness is recorded to confirm its sfficiency at work.

PHASE-5 Depuration

it is to verified that the program has been codded correctly.
