If the Class is Real world object then what kind of the classes under the class in school object in the perspective of the object oriented database management system model?

How to show the Class of their sub classes in according to object oriented database management system model of Class in school is a real world object?

This is the next post of the previous post class in school object. Please check it out the previous post. Here in this post we discuss about the Materials in Class, Electrical Fitting and Specification of class.

The Materials in class

It is a Class of the Class in School object which is connected to the Strong line as shown in the image. Their categories are divided into two parts of sub classes. One is Quantity of Materials and second is quality of Materials.

The Quantity of Materials

The Quantity of Materials is a sub class of ‘Materials in Class’. There are four fields or Attributes of a class that holds the data type of Character and Numerical. Such as How many wooden pieces in number or words quantity for apply on the class materials. Similarly, the Fiber doors, Glass of windows and Iron frame for windows in their quantity of materials.

{Quantity of wooden doors in number = Numerical Data type}

{Quantity of wooden doors in words = Character Data type}

{Quantity of Fiber doors in number = Numerical Data type}

{Quantity of Fiber doors in words = Character Data type}

{Quantity of Glass Windows in number = Numerical Data type}

{Quantity of Glass windows in words = Character Data type}

{Quantity of Iron Frame for Windows in number = Numerical Data type}

{Quantity of Iron Frame for Windows in words = Character Data type}

The Quality of Materials

The Quality of Materials is based on their atomic level quality and prizes goods quality according to their good or bad quality. These fields holds the character data type stores after checking the atomic level quality which is good or bad.

{Quality of Wooden door = Character Data type}

{Quality of Fiber door = Character Data type}

{Quality of Glass Windows = Character Data Type}

{Quality of Iron frame for windows = Character Data type}

The Electrical Fitting

This is a class of the ‘Class in school’ object. In the Class of The Electrical Fitting there are two parts of sub classes are ‘For Non Smart classes and ‘For Smart Class’.

For non-smart class Electrical switch board, ceiling fans and wires out fitting etc.

For smart class Electrical switch board, Dual AC [Warm and Cool] and Wires in fitting etc.

It holds both numerical and character data type in their fields of all Non-smart class and Smart class according to their quality and quantity of products.

The Specification of Class

This is a class of ‘Class in school’ object. There are six fields or properties/Attributes of their specification of class in number and in words. It holds both the character and numerical data type.

{Size of Width in number = Numerical Data type}

{Size of Width in words = Character Data type}

{Size of Height in number = Numerical Data type}

{Size of Height in words = Character Data type}

{Size of length in number = Numerical Data type}

{Size of length in words = Character Data type}

{Door for Enter in numbers and words = Character and Numerical Data type}

{Door for Exit in numbers and words = Character and Numerical Data type}

{Number of Windows in words and number = Character and Numerical Data type}
