OOPS

Resources:

 http://en.wikipedia.org/wiki/Object-oriented_programming

Object-oriented programming (OOP) is a programming paradigm using "objects" – usually instances of a class – consisting

of data fields and methods together with their interactions – to design applications and computer programs Programming techniques may include features such as data abstraction, encapsulation, messaging, modularity, polymorphism,

and inheritance Many modern programming languages now support forms of OOP, at least as an option

JAVA

Resources:

 http://en.wikipedia.org/wiki/Java_(programming_language)

Java is a programming language originally developed by James Gosling at Sun Microsystems (which has since merged into Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform The language derives much

of its syntax from C and C++, but it has fewer low-level facilities than either of them Java applications are

typically compiled tobytecode (class file) that can run on any Java virtual machine (JVM) regardless of computer architecture Java is a general-purpose, concurrent, class-based, object-oriented language that is specifically designed to have as few

implementation dependencies as possible It is intended to let application developers "write once, run anywhere" (WORA), meaning that code that runs on one platform does not need to be recompiled to run on another Java is as of 2012 one of the most popular programming languages in use, particularly for client-server web applications, with a reported 10 million users

Topics (Click to follow the link):

 Object-Oriented Programming Concepts teaches you the core concepts behind object-oriented programming: objects, messages, classes, and inheritance This lesson ends by showing you how these concepts translate into code Feel free to skip this lesson if you are already familiar with object-oriented programming

 Language Basics describes the traditional features of the language, including variables, arrays, data types, operators, and

control flow

 Classes and Objects describe how to write the classes from which objects are created, and how to create and use the

objects

 Interfaces and Inheritance describes interfaces—what they are, why you would want to write one, and how to write one

This section also describes the way in which you can derive one class from another That is, how a subclass can inherit fields and methods from a superclass You will learn that all classes are derived from the Object class, and how to modify

the methods that a subclass inherits from super classes

 Numbers and Strings describe how to use Number and String objects The lesson also shows you how to format data for

output

 Generics are a powerful feature of the Java programming language They improve the type safety of your code, making

more of your bugs detectable at compile time

 Packages are a feature of the Java programming language that helps you to organize and structure your classes and their

relationships to one another

C#

C# (pronounced "C sharp") is a simple, modern, object-oriented, and type-safe programming language It will immediately be familiar to C and C++ programmers C# combines the high productivity of Rapid Application Development (RAD) languages and the raw power of C++

Visual C# NET is Microsoft's C# development tool It includes an interactive development environment, visual designers for building Windows and Web applications, a compiler, and a debugger Visual C# NET is part of a suite of products, called Visual Studio NET, that also includes Visual Basic NET, Visual C++ NET, and the JScript scripting language All of these languages provide access to the Microsoft NET Framework, which includes a common execution engine and a rich class library The NET Framework defines a "Common Language Specification" (CLS), a sort of lingua franca that ensures seamless interoperability between CLS-compliant languages and class libraries For C# developers, this means that even though C# is a new language, it has complete access to the same rich class libraries that are used by seasoned tools such as Visual Basic NET and Visual C++ .NET C# itself does not include a class library

DATABASE/SQL

Resources:

 http://www.databasedir.com/what-is-rdbms/

RDBMS stands for Relational Database Management System RDBMS data is structured in database tables, fields and records Each RDBMS table consists of database table rows Each database table row consists of one or more database table fields

RDBMS store the data into collection of tables, which might be related by common fields (database table columns) RDBMS also provide relational operators to manipulate the data stored into the database tables Most RDBMS use SQL as database query language

Edgar Codd introduced the relational database model Many modern DBMS do not conform to the Codd’s definition of a RDBMS, but nonetheless they are still considered to be RDBMS

The most popular RDBMS are MS SQL Server, DB2, Oracle and MySQL

Web Development

HyperText Markup Language (HTML) is the main markup language for displaying web pages and other information that can be

displayed in a web browser

HTML is written in the form of HTML elements consisting of tags enclosed in angle brackets (like <html>), within the web page content HTML tags most commonly come in pairs like <h1>and </h1>, although some tags, known as empty elements, are unpaired, for example <img> The first tag in a pair is the start tag, the second tag is the end tag (they are also called opening tags and closing tags) In between these tags web designers can add text, tags, comments and other types of text-based content

The purpose of a web browser is to read HTML documents and compose them into visible or audible web pages The browser does not display the HTML tags, but uses the tags to interpret the content of the page

HTML elements form the building blocks of all websites HTML allows images and objects to be embedded and can be used to create interactive forms It provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items It can embed scripts in languages such as JavaScript which affect the

behavior of HTML webpages

SDLC

Resources:

 http://en.wikipedia.org/wiki/Systems_Development_Life_Cycle

SDLC (Software Development Life Cycle) is the process of developing software through business needs, analysis, design,

implementation and maintenance

Phases

Investigation

The 1st stage of SDLC is the investigation phase During this stage, business opportunities and problems are identified, and information technology solutions are discussed Multiple alternative projects may be suggested and their feasibility analyzed Operational feasibility is assessed, and it is determined whether or not the project fits with the current business environment, and

to what degree it addresses business objects In addition, an economic feasibility investigation is conducted to judge the costs and benefits of the project Technical feasibility must also be analyzed to determine if the available hardware and software resources are sufficient to meet expected specifications A legal feasibility study is important to discover any potential legal ramification The results of the feasibility study can then be compiled into a report, along with preliminary specifications When the investigation stage ends, a decision whether or not to move forward with the project should be made If it is decided to move

System analysis

The goal of system analysis is to determine where the problem is in an attempt to fix the system.This step involves breaking down the system in different pieces to analyze the situation, analyzing project goals, breaking down what needs to be created and attempting to engage users so that definite requirements can be defined

Design

In systems design the design functions and operations are described in detail, including screen layouts, business rules, process diagrams and other documentation The output of this stage will describe the new system as a collection of modules or

subsystems

The design stage takes as its initial input the requirements identified in the approved requirements document For each

requirement, a set of one or more design elements will be produced as a result of interviews, workshops, and/or prototype efforts

Design elements describe the desired software features in detail, and generally include functional hierarchy diagrams, screen layout diagrams, tables of business rules, business process diagrams, pseudo-code, and a complete entity-relationship diagram with a full data dictionary These design elements are intended to describe the software in sufficient detail that skilled

programmers may develop the software with minimal additional input design

Testing

The code is tested at various levels in software testing Unit, system and user acceptance testings are often performed This is a grey area as many different opinions exist as to what the stages of testing are and how much, if any iteration occurs Iteration is not generally part of the waterfall model, but usually some occur at this stage In the testing the whole system is test one by one Following are the types of testing:

 Defect testing the failed scenarios, including defect tracking

Operations and maintenance

The deployment of the system includes changes and enhancements before the decommissioning or sunset of the

system Maintaining the system is an important aspect of SDLC As key personnel change positions in the organization, new changes will be implemented, which will require system.
