Monolithic Programming

Table of Contents show

This programming consists only global data and sequential code
Example: Assembly language and BASIC
The global data can be accessed and modified (knowingly or mistakenly) from any part of the program, thereby posting a serious threat to its integrity
A sequential code is one in which all instructions are executed in the specified sequence
In order to change the sequence of instructions, jump statements or goto statements are used
Monolithic programs have just one program module as such programming languages do not support the concept of subroutines.

Structure of a monolithic program

	ADD	AX,B
	MOV	SUM,AX
	JMP	STOP
		
STOP:	EXIT

Monolithic programming languages are used only for very small and simple applications where reusability is not a concern

All the actions required to complete a particular task are embedded within the same application itself. This makes the size of the program large
Difficult to debug and maintain
