How to control application software development?

How to control application software development?

Controlling system of an application software is to provide the functionality changes through the form that takes input value on the form and make a change through the option in the regulator through on and off the option basically.

The radio button type function is used to perform a not gate system to show on and off by the given instruction to the radio button.

This option is mostly used to change the function or on the function or off the functions to make a change into the application software to provide the controlling system on the application to make changes according to the end user when the user takes decision to makes changes for uses of the application software functions according to the end user that makes easy ways to use the application software.


Introduction to the computer system related to the topic of computer system and application development and the topic is below here:


How to control application software development?


Let's discuss the computer and application development related topic of "How to control application software development?" and explained following below here:


How to control application software development?

There are some points on computer system and application software development related to the topic of "How to control application software development?" following below here:


How to control application software development?

  • Control design form is used to provide the options for controlling application function
  • Program is used to provide the controlling function to change some values to perform different task by the other option
  • Database is used to provide the control the data using the query language to provide the manipulation operation on the database file
  • Security model is used to provide the protection for user and the data using DCL


Let's discuss the points listed above about computer systems and application software development related to the topic of "How to control application software development?" explanation following below here:


Control design form is used to provide the options for controlling application function

Control on the design form to make changes on the design interface to change theme design also through the given option on the controlling system form included to change the color or text size or other types of system design related type of changes can be performed through the controlling system form on the application software.

Control design interface shows the input values to change the design theme of the application software to make a change of design form such as size of form, text size, button size etc. on the application software in the controlling system form interface of design to make changes by the end user through provided some options to an action on the control form on the application software.


Program is used to provide the controlling function to change some values to perform different task by the other option

Program is used to provide the controlling system on the application software to provide the functionality of controlling some values from the particular option developed for performing a task that changes to the different types of input resource or input resource key set.

The program can change the key setup to change the functionality of the task performed on the application software.

The program is used to provide the option that can change the functionality on the input resources on the computer system for the application software.

The program can be used to provide the functionality for changing the value of the application software to perform a task such as:- cut key setup is ctrl + m changes to the ctrl + x to perform cut operation on the text data.


Database is used to provide the control the data using the query language to provide the manipulation operation on the database file

Database is used to provide the control data using the query language program to perform an operation on the data in the relational database model. The relational database model included the records and attributes that makes a relational model for storing the different types of data in the form text data stores in a cell, the cell is a part of record and attribute when the record and attribute intersect to each other then the cell is developed and it is used to store on the relational database model.

Database is used to provide the controlling system using the manipulation command operation that is used to provide the output data on the attributes section or field of record.

The query language is used to process the data using the DML or Data Manipulation Language to perform operations on the database file to provide the management of the database file.

The data manipulation language included some keywords that are perform some operations such as:- update the data on the record, display the selected data through the record, insert the new data in the record to store new data with decided attributes, delete the data on the record or whole record can delete using keyword to perform on the relational database model file and stored data in the relational database file.

The data manipulation language is used to change the data and manage the data when the user wants to keep the database file the same but they want to change the data using the manipulation command operation on the database file.


Security model is used to provide the protection for user and the data using DCL

Security model is used to provide the protection for user and the database is used to provide the verification of the user data stores in the relational database model file and access through the integrated programming language program to access the database file through the connection string to provide the function that apply the command of data control language of SQL of the relational database model to apply on the record of the user who has an account on the application software database and it is need to verify the data of the application software on the security layer for end user to allow the permission to access their account when the username and password both are the verified on the DCL program of application security model.

The data control language is used to provide the verification system on the security model on the application software for the end user to provide the protection on the application software on the computer system.

The data control language from the SQL is used to process the data which is already mentioned or the saved the data in the record on the database file or relational database file on the application for the security model of the application software.

If the username and password are the data controlled attribute of the record of the relational database file from the security database file then the verification system is processed with the username and the password on the security model on the application software. And if the developers provided the new additional security feature with the new attribute such as:- secret code or ask any question on the security reference after the completely correct verification of the username and password on the security model on the application software.
