Brief History of Oracle



In 1977, Larry Elliso, Bob Minner, and Ed Oates formed a company called Relation Software Incorporated (RSI). This company built an RDBMS called Oracle. Ellison,, Minner, and Otates made a key decision: to develop their RDBMS using C and SQL interface. Soon after, they came out with version 1, a prototype.

In 1979, RSI delivered its first product to customers. The Oracle RDBMS version 2 worked on the Digital PDP-11 running the RSX-11 operating system and was soon ported to the DEM VAX system.

1983 heralded the release of version 3, which touted changes in the SQL language as well as performance enhancements and other improvements. Unlike earlier versions, version 3 was written almost entirely in C. At this point, RSI changed its name to Oracle Corporation.

Oracle version was released in 1984. This version supported both the VAX system and the IBM VM operating system. Version 4 was the first version to incorporate read consistency version 5, introduced in 1985, was a milestone because it introduced client/server computing to the marker with the use of SQL*net. Version 5 was also the first MS-DOS product to break through the 640KB barrier.

In 1988, Oracle presented version 6, which introduced low-level locking as well as a variety of performance improvements and functionality enhancements, including sequence generation and deferred writes. I was introduced to Oracle was days when we even variety of different platforms and operating systems.

In 1991, Oracle introduced the Oracle Parallel Server option on version 6.1 of the Oracle RDBMS on the DEC VAX platform. Soon the Parallel Server option was available on a variety of platforms.

Oracle7, released in 1992, included many architectural changes in the area of memory, CPU, and I/O utilization. Oracle7 is the full-featured RDBMS to which you are accustomed, the one you’ve been using for many years. Oracle7 introduced many advance in the area of ease of use, such as the SQL*DBA tools and database roles.
Finally, in 1997 Oracle introduced Oracle8, which added object extensions as a host of new features and administrative tools.

For more information about the history of Oracle(specifically about the Oracle server), check out the two-part article by Ken Jacobs in the January(February and March/April 1995 issues of Oracle Magazine.

Benefit of Object Oriented Programming

Object-orientation contributes to the solution of many problems associated with the development and quality of software products. The technology provides greater programmer productivity, better quality of software and lesser maintenance cost. The principle advantage are;

1)
Through inheritance we can eliminate redundant code and extend the use
of existing classes.
2)
We can built programs from the standard working modules that communicate
with one another, rather than having to start writing the code from scratch.
This leads to saving of development time and higher productivity.
3)
The principle of data hiding help the programmer to built secure programs
that cannot be invaded by code in other parts of the program.
4)
It is possible to have multiple instances of an objects in the program.
5)
It is easy partition the work in a project based on objects.
6)
The data-centered design approach enables us to capture more details of
a model in implementable from.
8)
Object-oriented systems can be easily upgraded from small to large systems.
9)
Message passing techniques from communication between objects makes the
interface descriptions with external systems much simpler.
10)
Software complexity can be easily managed.

While it is possible to incorporate all these features in an object-oriented systems. Their importance depends on the type of the project and the performance of the programmer. There are a number of issues that need to be tackled to reap some of the benefits stated above. For instance, object libraries must be available for reuse. The technology is still developing and current products may be superseded quickly. Strict controls and protocols need to be developed if reuse is not to be compromised. Developing a software that is easy to sue makes it hard to built. It is hoped that the object-oriented programming tools would help manage this problem.

Basic Concepts of Object Oriented Programming

Procedural programming deals with functional parts of the problem. Programmers identify what actions must be taken to solve the problem at hand. Let us now, try to understand what aspect of problems are dealt with in object-oriented approach object-oriented.

In object-oriented, a problem is viewed in terms of the following concepts:

1. Objects
2. Classes
3. Data abstraction
4. Data encapsulation
5. Inheritance
6. Polymorphism
7. Dynamic binding
8. Message passing

1.OBJECTS:


Objects are the basic run-time entities in an object-oriented system. They may represent a person, a place, a bank account, a table of data; they also represent user-defined data such as vectors, time and lists. They accupy space in memory that keeps its state and is operations on the object. Each object contains data and code to manipulate the data. Objects can interact without having to know details of each other data or code.
2. C LASSES: A class represents a set of related objects. The class of an objects defined what attributes an object has. The entire set of data and code of an object can be made a user-defined data type with the help of a class. Classes are user defined data types that behave like the built-in types of a programming language. Classes have an interface that defines which part of an object of a class can be accessed from outside and how. A class body that implements the operations in the interface, and the instance variables that contain the state of an object of that class.

3.DATA ABSTRACTION:


Abstraction refers to the act of representing essential-features without including the background details or explanations. Abstraction is indispensable part of the design process and is essential for problem partitioning essentially is the exercise in determining the components are not isolated from each other, they interact with each other. Since the classes use the concept of data castration, they are known as Abstract Data Type(ADT).

4.DATA ENCAPSULATION:


The wrapping up to data and functions into a single unit (class) is known as encapsulation. Data encapsulation is the most striking feature of class. The data is not accessible to the can access it. These functions provide the interface between the object’s data and the program. This insulation of the data from direct access by the program is called data hiding.

5.INHERITANCE:


Inheritance is the process by which objects of one class acquire the properties of objects of another class. It supports the concept of hierarchical classification, for example, an manager class is a type of the class employee, which again is a type of the class person as illustrated below. The principle behind this sort of division is that each derived class shares common characteristics with the class from which it is derived. The power of inheritance lies in the super class. In other words, a feature is placed in the higher level of abstraction. Once this is done, such features can be inherited from the parent class and used in the subclass and used in the subclass directly. This implies that if there are many abstract class definitions available, when a new class is needed, it is possible that the new class is a specialization of one or more of the existing classes.

6.POLYMORPHISM:


Polymorphism means the ability to take more than one from. An operation may exhibit different behavior in different instance. The behavior depends upon the types of the data used in the operation. The process of making operator to exhibit different behavior at different instance is called operator overloading. Another example of polymorphism is function overloading, where a single function can perform various different types of task.

7.DYNAMIC BINDING:


Binding refers to the linking of procedure call to the code to be executed in response to the call. Dynamic binding means that the code associated with a given procedure call is not known until the time of call at run-time, the code matching the object under reference will be called.
8.

MESSAGE PASSING:


Message passing is another feature of object-oriented programming. An object-oriented program consists of a set of objects that communicate with each other. The concept of massage passing makes it easier to talk about build systems that directly model or simulate their real-world counter-parts. A message for an object is a request for execution of procedure, and desired result. Message passing involves specifying the name of the object, the name of the function (message) and the information to be sent.

Really Simple Syndication RSS


Really Simple Syndication


We are familiar with the phrases ‘surfing the web’ browsing the internet’, but with the wealth of websites now online, carrying out the daily trawl of your favorite sites can be a time-consuming task – not to mention to offer.

But this need not be the case. Many websites now offer services called Really Simple Syndication (RSS), although it is often referred to simply as a feed. The feed is job is to bring the content from your favorite sites directly to you. When RSS first appeared, you needed a special program to receive feeds, but it is now possible to subscribe to them free of change from within your web browser, and this feature is going to show you how. And remember, feeds are not just for tracking news – you can also use them to get travel information, ticket updates for events and more.

What is RSS


In a nutshell, an RSS feed is a standardized format used to publish frequently updated web content. Any single feed might typically contain such information as a headline, and either a full rendition or a summary of the article, a publishing date and an author name.

The latest versions of RSS formats are created using a language called XML, which lends it great flexibility. As you browser the web you may encounter references to Atom feeds, which sound a lot like RSS. For all intents and purpose, they are the same thing. At some point in history, Atom was set up as an alternative to RSS, but almost all browsers and RSS readers are capable of accessing feeds in both formats.

Now that RSS feeds are so easy to use, you’ll discover feeds in more places than you would expect. Such as RSS feeds to keep customers up to date with the latest offers www.tesco.com/rss. travel website Last minute publishes feeds with updates on bargain holiday and theater offers (www.snipurl.com/4lnqk). Let us not forget, of course, that RSS is also ideal for keeping track of your favourit blogs and news-driven websites such as the
DNA (www.dnaindia.com/services/rss).

Being able to spot when a website is offering an RSS feed is also getting easier. Many sites these days plump for the increasingly familiar orange box, featuring a white wave-like design. But that is not to say they all do. Instead of the orange icon, you might also look out for a small rectangular box in orange or white with the word RSS written on it. And while orange is the predominant color associated with feeds there are still plenty of unconventional icons out there.

It used to be the case that you needed to download a special program called an RSS reader to subscribe a special program
