The severity of these problems can be 
significantly reduced through the use of modern 
structural methods, among which structural analysis 
methodologies are central.

PRINCIPLES 
OF 
STRUCTURAL 
ANALYSIS 
It is customary to call a structural analysis a 
method for studying a system, which begins with its 
general overview and then details it, acquiring a 
hierarchical structure with an increasing number of 
levels. All structural analysis methodologies are based 
on some general principles and guidelines. 
The following two basic principles are used: the 
principle of "divide and conquer" and the principle of 
hierarchical ordering. The first principle means 
breaking complex and time consuming tasks into 
many smaller independent subproblems. The second 
declares the organization of parts of the system into 
tree-like hierarchical structures, i.e. the system can be 
understood and built in levels, each of which adds new 
details. 
In addition to two basic principles, there are a 
number of others, no less important. Some of them 
are: the principle of abstraction, formalization, 
conceptual generality, consistency, etc. 
DATA-FOCUSED 
STRUCTURAL 
ANALYSIS METHODOLOGIES 
There are many methodologies for structural 
analysis designed to solve specific problems. Since we 
are interested in information systems development, 
we will only consider data-driven methodologies. The 
development of an enterprise-wide information 
system is a rather laborious and lengthy process. The 
combination of these two factors - the laboriousness 
of the development process and the information 
content (data orientation) of the software being 
developed - most often determines the choice of one 
of the existing DBMS as a development tool and 
method of presenting information.
