Visual Foxpro defination usage advantages and features

Visual Foxpro is a dynamic object oriented language that supports multiple class libraries, a class browser. It provides programmable dynamic (run-time) subclassing, and data dictionary capabilities. Microsoft Corporation released Visual Foxpro in June 1995, shortly before the introduction of Windows 95. Similar to Visual Basic, Visual Foxpro (VFP) is a RAD tool that uses ActiveX visual components, and interoperates through OLE automation or by creating COM servers. VFP can also subclass ActiveX components and COM automation objects.

Instantiating an object or creating an Object

Once we know that a class exist we can use new() keyword for creating object of it.

we must create the main program that will instantiate the object. We will call the main program class TestClass. It should look just like how every other java program starts off.

 

public class TestClass
{
   public static void main(String[] args)
   {
   }
} 

Now we will instantiate the object. To do this we declare a reference to the object called stu and set it equal to a newly created object in memory.

 

Class of object definition

A class is the code for an object and an object is the instance of a class in memory. When you create an object from a class it is called instantiating the object.

A definition by its official site:-

"A class is a blueprint or prototype from which objects are created. This section defines a class that models the state and behavior of a real-world object. It intentionally focuses on the basics, showing how even a simple class can cleanly model state and behavior."

 

Object-Oriented Programming(OOP)

Object oriented programming or OOP is a way of writing programs using objects where each object has its attributes and set of operations defined by its class. An object is a data structure in memory that has attributes and methods. The attributes of an object are the same as variables and the methods of an object are the same as functions or procedures.

 

Object-relational database Model

An object-relational database (ORD) or object-relational database management system (ORDBMS) is a database management system (DBMS) similar to a relational database, but with an object-oriented database model: objects, classes and inheritance are directly supported in database schemas and in the query language. In addition, it supports extension of the data model with custom data-types and methods.
Example of a Object-Oriented Database Model.

 

What is Object-Oriented Programming?

Object oriented programming or in short OOP is a way of writing programs using objects. An object is a data structure in memory that has attributes and methods. The attributes of an object are the same as variables and the methods of an object are the same as functions or procedures.
