<span style="font-family: "Times New Roman","serif"; font-size: 12.0pt;">The
computer programs are the means used by human beings for communication with the
machines especially the computers. As you all know, programs or the software
contain instructions for the hardware to accept inputs, to process those inputs
according to the instructions and to produce information as per the
instructions contained in the program. The term ‘programming’ today is used to
define the solution to a specific problem to be solved with the help of
programs and it is said to define its solutions in terms of its design,
creation, testing, debugging, implementation and its maintenance. Throughout
the history of programming, ever increasing complexity of the problems to be
solved using computers has encouraged the researchers and developers to evolve
better means to manage this complexity. Complexity and intended areas of
application coupled with some other factors have led to the evolution of a
number of programming paradigms. Various programming languages are in use today
depending upon various existing programming paradigms. The structured
programming and the Object-Oriented Programming (OOP) paradigms are the two
paradigms that have been drawing attention of programmers for last so many
years. The term OOP was used by Xerox PARC for the first time in its
programming language, Smalltalk referring to the usage of objects as
computational units for processing. The language Smalltalk itself got its
inspiration from another OOP language called Simula 67 developed under the
aegis of Simula Project in late 60s. The feature of inheritance introduced for
the first time in Smalltalk allowed it to surpass both Simula 67 as well as
other analog programming systems. Simula 67 and Smalltalk paved the way for
many other OOP languages including C++ by 1980s.<o:p></o:p></span></div>

general, a System is based on Input-Process-Output (IPO model). Manual work can
be replaced by computerized system for accuracy and speed of processing. So,
before the development of any computerized system, developers should also
understand all basic concepts about the system. To develop a system, a standard
Methodology must be considered. Different approaches are available for the
development of a system. Selecting the best approach is the responsibility of
systems analyst and this selection is based on the requirements of end user,
problem definition and the infrastructure provided. Standard principles should
be followed for the development of good quality software.<o:p></o:p></span><br />

<span style="font-family: "Times New Roman","serif"; font-size: 12.0pt;">A
common person’s belief is that a computer can do anything. This is far from
truth. In reality, computer can perform only certain predefined instructions.
The formal representation of this model as a sequence of instructions is called
an algorithm, and coded algorithm, in a specific computer language is called a
program. Analysis of algorithms has been an area of research in computer
science; evolution of very high speed computers has not diluted the need for
the design of time-efficient algorithms.<o:p></o:p></span></div>
<div class="MsoNoSpacing">
<span style="font-family: "Times New Roman","serif"; font-size: 12.0pt;">Complexity
theory in computer science is a part of theory of computation dealing with the
resources required during computation to solve a given problem. The most common
resources are time (how many steps (time) does it take to solve a problem) and
space (how much memory does it take to solve a problem). It may be noted that
complexity theory differs from computability theory, which deals with whether a
problem can be solved or not through algorithms, regardless of the resources
required.<o:p></o:p></span></div>

<div class="MsoNoSpacing">
<span style="font-family: "Times New Roman","serif"; font-size: 12.0pt;">Analysis
of Algorithms is a field of computer science whose overall goal is understand
the complexity of algorithms. While an extremely large amount of research work
is devoted to the worst-case evaluations, the focus in these pages is methods
for average-case. One can easily grasp that the focus has shifted from computer
to computer programming and then to creation of an algorithm. This is algorithm
design, heart of problem solving.<o:p></o:p></span><br />

every segment of commercial, academic and virtual world. They are required as
the backbone of any information system, enterprise resource planning, research
activities and other activity that require permanence of data storage. Database
management systems manage data more efficiently and effectively. Presently
almost all popular commercially available database management system support
relational model although many extensions of this model have been in existence.
Some of these DBMSs have been extended to include many advanced features such
as object-oriented support for graphical objects, vary large objects etc.<o:p></o:p></span></div>

<div class="MsoNormal">
<span style="font-family: "Times New Roman","serif"; font-size: 12.0pt; line-height: 115%;">Block 1 covers the basic concepts of RDBMS including
the three level database Architecture, the two most important models for
databases; the relational and entity relationship models, the integrity
requirements of databases, issues relating to normalisation of database and
basics about the conventional file organisation.<o:p></o:p></span></div>

structured query language (SQL), the standard query language of commercial
DBMS. In addition, the concepts of Database Recovery, transaction management
and security have also been covered in this Block. This block also introduces
the concepts of the distributed and client server database.<o:p></o:p></span></div>

<div class="MsoNormal">
<span style="font-family: "Times New Roman","serif"; font-size: 12.0pt; line-height: 115%;">Block 3 and Block 4 are oriented towards development
of a database system using DBMS software. Before, reading these blocks, you
must thoroughly go through the concepts given in block 1 and block 2 as they
will be required for any relational database management system application
development. Block 3 focuses on database development steps involving creation
of tables, relationships among tables, forms, reports and queries using the
tools of a DBMS. Block 4 on the other hand highlights the complete process of
development of a Database system for an organisation. It also briefs the
process of the system development.<o:p></o:p></span></div>

must keep up pace with it. Specially in the client-server levels of databases,
server side will be the designs you undertake here, whereas client side
development may involve various tools that may be available with the DBMS such
as report writers, form designers, ER diagramming tools etc. You must try to
practice on available DBMSs on Linux and Windows operating systems.</span><o:p></o:p><br />

<span style="font-family: "Times New Roman","serif"; font-size: 12.0pt; line-height: 115%;">Logic is the study and analysis of the nature of the
valid argument, the reasoning tool by which valid inferences can be drawn from
a given set of facts and premises. It is the basis on which all the sciences
are built. Logic was extensively studied and developed in ancient Greece. But
the mathematical theory of logic, called symbolic logic, only came into its own
in the 19th century. This algebraic way of studying arguments was developed by
the English mathematician George Boole (1815-1864).</span><o:p></o:p><br />

component of computer programming and in this block the primary focus of this
course is to teach the basic programming constructs of C language. Emphasis is
placed on developing the student's ability to apply problem-solving strategies
to design algorithms and to implement these algorithms in a structured
procedural programming language. This course includes a laboratory component
also where in which the student gets the hands on experience. Basically one
must explore possible avenues to a solution one by one until s/he comes across
a right path to an optimize and efficient solution. In general, as one gains
experience in solving problems, one develops one's own techniques and
strategies, though they are often intangible.</span><o:p></o:p><br />
