Before starting System
Architecture let us know about the basic terms related to it.
Data structure:
A data structure is a way of organizing data
that considers not only the items stored, but also their relationship to each
other.
Algorithm: An algorithm is a procedure or formula for solving a problem
and process the data.
Database: Database
is collection of information that is organized to be accessed , managed and
updated.
Application:
Application deals with access of data from the database using different algorithm.
Now
question is ,What is Integrated System and Why we use it ?
The
Integrated Systems explores the technologies and designs that aims to connect
people to other people and information , what matters to them most.
Integrated
System is of 4 types,
Single Tier Integrated System: Here we need data
separate data from application
Two Tier
/Client Server Architecture:In a 2-tier architecture, business-logic is implemented on the PC. Even
the business- logic
never makes direct use of the windowing-system.It enable
the client and server system to communicate and pass data back and forth and
establish a transparent interface among the systems.
Three Tier Architecture and Multi Tier Architecture:
Three-tier is a client-server architecture in which the user interface,
functional process logic , data storage and data access are developed and
maintained as independent modules, most often on separate platforms.
