Features And Advantages Of Object Oriented Programming Languages

An object-oriented programming language (also known as OO language) is one that allows a website development service to use object-oriented programming techniques including inheritance, modularity, polymorphism and encapsulation. The first language to boast primary features of an object-oriented programming language was the Simula. The Simula was released in 1967 followed by Smalltalk, which was in huge demand between 1972 and 1980. In fact, Smalltalk is one of the best examples of object-oriented programming.

Pure OO languages have everything in them treated as an object. From primitives to prototypes, classes, blocks and modules, these languages were designed to enforce and facilitate OO methods. Examples of pure OO languages include Eiffel, Ruby and Smalltalk.

A custom web development expert employs object-oriented programming languages in the web development process. Here are some features of Object-oriented programming languages in website development services:

Quick Turnaround Time: OO languages have a comprehensive code library that a programmer employs in developing websites. With an extensive code library, the programmers can develop web sites in a quick, competitive and economical manner.

Quick Output: The coding under Object Oriented programming language is highly systematic and organized. Programmers can on a project with ease without affecting the pace of web page development.

Objects and methods developed can be reused in other programming languages: Object oriented programming ensures development of reusable code library. Programmers can reuse the objects, block and modules in other projects and programming languages.

Modern-day Object Oriented programming languages run on Windows, Mac OS, Linux/Unix operating system, Palm Handhelds and .Net virtual machines. Here are some benefits of using a modern-day object oriented programming language in websites development:
OO programming languages have a very clear and readable syntax
They boast exception-based error handling techniques
They feature high level and dynamic data types
There is a natural expression of procedural code
OO languages include high level third party modules and extensive standard libraries

Most OO languages are flexible enough to handle any domain problems. Some OO languages such as Python allow programmers to build web servers in three lines of code. This ensures error-free web development.

Exchange Server Recovery to Fix Transport Database Corruption

Are you facing fatal errors while accessing your Microsoft Exchange Server 2007 database? Is your EDB (Exchange Server Database) file is inaccessible? The fatal error in Exchange server aborts the application and thus makes it unusable. This behavior of MS Exchange Server renders all your valuable data inaccessible and cause critical data loss situations. In order to get your precious data recovered in such situations, you need to repair and restore the damaged EDB file, using an EDB Recovery solutions.

As an example, MS Exchange Server 2007 Management Pack for Operations Manager supervises the MS Windows Application Event log on systems, which are running MS Exchange Server 2007 and returns the below event:

“Product Name: Exchange
Product Version: 8.0 (Exchange Server 2007)
Event ID: 17003
Event Source: MSExchangeTransport
Alert Type: Critical Error
Description: A Transport database operation has encountered a fatal error. The database may be corrupted. The Microsoft Exchange Transport service is shutting down. Manual database recovery or repair may be required.”

After the above error, Microsoft Exchange Server does not let you access your database. At this point, you have to verify the cause of this problem and perform EDB File Recovery by resolving it.

Cause:

The error message below indicates that specified ESE (Extensible Storage Engine) database is damaged. It is preventing MS Exchange Server services from starting.

– ESE, also called JET Blue, is an ISAM (Indexed Sequential Access Method) data storage technology intended by Microsoft. The ESE is particularly used as a key component of the Microsoft Exchange Server and the Active Directory.

How to Fix ESE Corruption:

You can carry out following things to sort out this issue-
1. Delete the defined database and corresponding transaction logs. You must not remove the database if you have significant data in the database.

2. Repair the damaged database using Isinteg.exe tool or restore it from backup.

However, if none of the above methods helps you to work around the problem, EDB Recovery Tool is the only option to go for. They carry out in-depth scan of entire EDB file using high-end scanning techniques and restore all database objects such as emails, notes, contacts, tasks, and more.

The software enable you to recover corrupt EDB file in a quick and easy way as they are incorporated with simple and self-descriptive graphical user interface. The integrity of your database is always preserved by these tools.

EDB Recovery Software is the most preferred recover EDB solution to repair and restore EDB files in all cases of corruption. The EDB Recovery is designed for Microsoft Exchange Server 2007, 2003, 2000, and 5.5.

What Is A Name Server

The computer cannot understand English or any other common language. The internet is a network of such computers that do not understand the language that the common man understands. This means that a domain name typed in like www.yourdomain.com will not mean anything to the computer. This domain name that you type in needs to be translated into a string of numbers for the computer to understand it. This string of numbers is called IP Address. It looks like this: 202.157.34.10.

It is not easy to remember a string of numbers like a domain name. Hence, we use domain names that we can understand and those domain names have corresponding IP Addresses that the computer can understand. But if this has to work, then every domain name should be translated into an IP Address that the computer understands. This translation is done by Name Servers. A name server is familiar with a domain name and their corresponding IP Addresses. Name Servers are also called Domain Name System Servers or DNS Servers.

All the information from all the name servers around the world is stored in a central registry. It takes between 8 and 48 hours for all the information to be updated in the central registry when a new domain name is registered. Name Servers from around the world can access this registry and when the domain name is requested, they can get the corresponding IP Address from this registry.

A domain name, when registered, needs at least two name servers. These are usually ns1.nameservername.com and ns2.nameservername.com. Here, “nameservername” is the name of the server. The first one is the primary name server and the second one is the secondary name server. The secondary name server acts as a backup that comes into effect only when the first name server is not responding.

Certain steps need to be followed while registering a domain name. These may differ a little depending on the registrar, but most of the steps are the same.

If you need to register a .com domain name, the steps are given below :
1. You get an account with the domain name registrar when you register a domain name. Log into your account with the registrar.
2. You will see an option to manage your domain name within your account console.
3. Select the domain name for which you want a name server. This will open a page for managing the domain.
4. Select “add name servers” on this page under the name server details section.
5. Enter the name and IP Address of the new name server and click on “Add”.
6. You should get a confirmation message indication that you have added a new name server once you are done with registering it.
7. Normally, you can start using the new name server immediately.

Descriptive Programming In Qtp – Part 1

Hello Friends,
In this series of post, we’ll learn about Descriptive programming (DP).

There are two ways, QTP uses to recognize the objects present in your application.

1. Object Repository (OR)
2. Descriptive Programming (DP)

First let see how OR works. OR is the simple and default way of object identification in QTP. OR stores groups of properties and values of every object. While you record on application, all the objects you click, are stored in Object Repository.

During the play back QTP use this OR to identify the object on which the action is to be performed.

What is Descriptive programming (DP)?

We’ll use DP when we want to bypass OR. Descriptive programming is used when we want to perform an operation on an object that is not stored in the object repository. This way QTP wont search for the object properties in the OR, but will take it from the DP statement.

Why use Descriptive programming (DP)?

Everything looks fine while automating test using OR then why should I use DP?

Well, there might be many valid reason to do so. Think about a situation – you want to close all opened browser automatically before you start executing your script. Here OR will not help you to identify an object as it is not possible to store all the opened browser objects into OR. Make sense?

No worries! We’ll discuss the need and benefits of DP in detail later in this post. Well examine scenarios where ORs advantages are outweighed by the DP.

I am not very good in vbscript. Is it mandetory to learn vbscript explicitly to write DP?

No. Not at all! Its not mandetory, but yeah.. recommended. For basic opretions and starting with DP, this post will guide you.
Although, for advanced oprations i.e. using COM, AOM, complex framworks etc. vbscript knowledge is the key.

Okie guys! Now, lets start writing DP!

Writing Descriptive Programming (DP):

DP can be written in two ways..

1. Static (by provide the set of properties and values directly)
2. Dynamic (by creating description object)

Static:

– In Static method of DP, we provide the set of properties and values directly in a single line, in form of the string arguments.

Here is the format/syntax of DP..
object’s Class Name(“property name:=property value)
Exmp 1: webbutton(Name:=Google Search)

object’s Class Name = webbutton
property name = Name
property value = Google Search

Exmp 2:- Browser(google).page(google).webbutton(name:=Google Search,type:= Submit).click

In above statement, Browser(google) and page(google) are written using OR. And webbutton(name:=Google Search,type:= Submit) is written using DP. Please note that we can write multiple set of properties and values in any DP statement.

Examples:
webbutton(name:=Google Search).click

What Is The History Of Java Programming Language

C language developed in 1972 by Dennis Ritchie had taken a decade to become the most popular language amongst programmers. But, with time programmers found that programming in C became tedious cause of its structural syntax. and Before it emerged as a programming language, C++ was a dominant player in the trade.primary goals that the creators of this language was to create a language that could tackle most of the things that C++ offered while getting rid of some of the more tedious tasks that came with the earlier languages.

In 1990 James Gosling,Bill Joy and others at Sun Microsystems began developing a language called Oak. Gosling called the language Oak in honor of a tree that could be seen from his office window. Sun found that Oak could not be trademarked because of a product already using the name. After sessions in January 1995, The meeting, arranged by Kim Polese where about a dozen people got together with James Gosling,and the final suggest names were Silk, DNA, Ruby, WRL and Java by the team in meeting But the other names could not be trademarked. So finally, name java was first suggested by Chris Warth. because it sounded the coolest and decided to go ahead with it.

This group wanted household items devices like thoughtful toasters, sagacious Salad Shooters and lucid lamps. To communicate with each other. To serve these goals, Oak needed to be Platform independent,Compact and Extremely reliable. so,The first public implementation was Java 1.0 in 1995. It made the promise of “Write Once, Run Anywhere”, with free run times on popular platforms. It was fairly secure and its security was configurable, allowing for network and file access to be limited.

By 1994 Sun’s Hot Java browser appeared. It was Written in Java in only a few months,and it illustrated the power of applets, programs that run within a browser, and also the capabilities of it for speeding program development. this language quickly received widespread recognition and expectations grew for it to become the dominant software for consumer applications and browser.

but,the early versions of it did not possess the breadth and depth of capabilities needed for client applications. Applets became popular and remain common but don’t dominate interactive or multimedia displays on web pages. It’s capabilities grew with the release of new and expanded versions and it became a very
popular language for development of enterprise, or middle ware, applications like on line web stores, transactions processing, database interfaces.

Today,It has become quite common on small platforms such as cell phones and PDAs.It not only permeates the Internet, It is the invisible force behind many of the applications and devices that power our day-to-day lives. From mobile phones to handheld devices, games and navigation systems to e-business solutions, Java is everywhere.

General Concepts about Object-Oriented Programming

The programming style that we usually call object-oriented programming (OOP) has appeared relatively recently in the history of programming languages. This is a particular and very convenient style for many situations. It was designed to overcome the limits of structured programming based mainly on the widespread use of procedures, functions, pointers or other more or less developed data types.

Although structured programming is very practical for small software systems or reduced non-graphic applications, it should be avoided when dealing with large applications that use graphic elements where object-oriented programming is recommended. Object orientation means organizing software resources as a collection of distinct and discrete objects, which includes both data structures and their processing functions. This organization is an extension of structured programming in which the data structures and processing functions are only loosely connected. All items have their own identity and are perfectly distinct.

An object is defined as an abstract concept, a specific and useful element for any application. Objects serve two specific purposes:

– they provide a better understanding of the problem to be solved;

– they provide a base design for implementation.

A class of objects encapsulates a certain number of objects with similar properties. This similarity refers to both the description (data and attributes) and the behavior (functions or methods). Attributes are unique features within an object class. Each attribute receives a certain value which can be modified during the objects life cycle. Two or more objects can have the same or different values for the same attribute.

Methods or operations are processing functions applied to objects of a certain class. All objects within a class admit the same set of methods, methods which in return may receive any number of additional parameters. In order to apply various methods to an object, it has to be created (defined). Defining an object is called instantiation. Once an object has fulfilled its mission it is removed.

Abstraction is a fundamental human trait that allows us to build models and thus cope with complexity. In every field of human activity, project approach is based on building a model for a better understanding of the problem to solve. Software engineering makes no exception. Through abstraction the essential key aspects are isolated from the non-essential ones. Therefore, each problem might have several adequate models.

In the software engineering industry, structured programming has made a big step forward defining three perspectives needed in order to properly address any application. These perspectives, also known as models, are: the static model, the dynamic model and the functional model.

There are currently several object-oriented methodologies used for analysis, design and implementation of software resources. One of these modeling methodology is the OMT (Object Modeling Technique) methodology. This method of modeling involves the planning of the various development stages and a graphical representation of objects and their relationships.

History of PHP and Advanced Development in PHP Programming

The original PHP release was created by Rasmus Lerdorf in June 1995 for his own personal use, to make various common web programming tasks easier and less repetitive and to track the visitors to his online resume.

In 1997, the software transformed from a personal development project into a professional development effort. The name originally stood for “Personal Home Page,” but has since become a recursive acronym, standing for PHP Hypertext Processor.

The goal of this release was to minimize the amount of code required to achieve results, which led to PHP being HTML centric–that is, PHP code was embedded inside HTML.

The second PHP release, known as PHP/F1 2.0 was the first to achieve wide spread popularity, and despite the parsing inconsistencies, it managed to attract a few converts.

The release of PHP 3 was largely driven by Zeev Suraski and Andi Gutmans, who rewrote PHP from the ground up and removed the parsing problems. PHP 3 also made it much easier for others to extend the language. PHP 3 has live up to the design goals of improving the performance of complex applications and modularity of PHP’S code base. Apart from this, it provides end users with a solid infrastructure for lots of different databases, protocols and APIs.

Its successor, PHP 4, contained numerous major changes, including Zend Engine. PHP 4 has introduced multi-threading, which essentially allows particularly lengthy, but non-critical functions to be run independently from the main script process, further streamlining execution.

The engine took over the core of PHP and introduced reference counting, whereby all resources used in scripts (database connections, files, etc) are tracked automatically by the engine, and freed when no longer used to minimize memory usage and ensure there were no memory leaks. In short, Zend engine, take a leading role in improving the performance of PHP scripts.

PHP 5 offers three different types of properties: public, protected and private properties. PHP 5 was released powered by the new Zend Engine II. PHP 5 included new features such as:

Support for object-oriented programming, better support for MYSQL, embedded support for SQlite and integrated SOAP support.
The PHP Data Objects extension, which defines a light weight and consistent interface for accessing databases.
Performance enhancements
Data iterators
Error handling via exceptions

Although not as vast as the jump from PHP 3 to PHP 4, the move from PHP 4 to PHP 5 is still a big one.

Along with hugely improved object orientation, the addition of try/catch error handling, and exceptions, there are two major new extensions: simple XML, a fast and easy-to-learn way to interact with XML documents, and SQLite, a new flat-file database API that eases the burden of deploying simple database solutions.
