Application Program Code
An Application is a Set of Program to validate and manage Business Information in the Data File or Database. Program is a Set of Statements to Validate Input Data with Business Process Information to ADD / EDIT / DELETE Business Information in the Data File or Database and then VIEW Business Information from the Data File or Database. An Application Program Code can categories into three different types is called "Presentation Code", "Business Process Code" and "Data Process Code".
Presentation Code
Presentation Code can categories into two types is called Input Screen or Output Screen. Input Screen is help to get Business Information from the Application User to store data in the Data File or Database and Output Screen is help to display Business Information to the Application User from Data File or Database.
An Application Presentation Code can write through traditional Character User Interface Language (CUI) or advanced Graphical User Interface (GUI) Program Language. The CUI Presentation Code is called Screen and GUI Presentation Code is called Window Form or Web Page.
Business Process Code
A Business is operating through collection of Information with Set of Function and Procedure. Business Process Code is help to validate Input Business Information and update Data File or Database and then help to generate Management Information Report.
The Information validation can categories into two types are called Application User Data Validation (Client Side Validation) or Database Data Validation (Server Side Validation). The Data Validation Code is help to conform the Input Information like Data Type, Data Format, Domain Rules and Data Existence in the Database. These types of validation are help to manage Business Information in the Data File or Database.
By the help of Object Oriented Analyze and Design Concept, the Core Business Process Code can encapsulate and create a Business Component File to reduce volume of Application Code and Complex Process Code.
Data Process Code
Data Process Code is help to ADD / EDIT / DELETE Business Information in the Data File or Database and then VIEW Business Information from the Data File or Database.
In the traditional Application Development Environment (1950 - 1970), every Business Information categorized and stored in the Computer System like Data File and maintain through Program. No Intelligence Process to Manage Business Information. The Data Structure and Data Information manage through Program and difficult to write Data Process Code to manage Business Information in Program File.
Database Management System was invented with Structured Query Language to manage Business Information in the Database. Database Management System is a Set of Computer Programs to Create and Maintain Business Information in the Database. The Data Structure and Data Information manage through Database. Database Management System is help to reduce volume of Application Code and Complex Process Code.
In the advanced Application Development Environment, the Program Code should establish connection with Database through ODBC, JDBC and OLE DB and then Execute SQL Statements to INSERT / UPDATE / DELETE Business Information in the Database and then SELECT Business Information from the Database.
