Oracle Features
Oracle Features
The Oracle database is a broad and powerful product.
To give some structure to the broad spectrum of the Oracle database, we’ve organized the features into the following sections:
• Database application development features
• Database connection features
• Distributed database features
• Data movement features
• Performance features
• Database management features
Database Application Development Features
The main use of the Oracle database system is to store and retrieve data for applications. The features of the Oracle database and related products described in this section are used to create applications. We’ve divided the discussion in this section into two categories: database programming and database extensibility options. Later in this chapter, we describe the Oracle Developer Suite, a set of optional tools used in
Oracle Database Server and Oracle Application Server development.
Database Programming
All flavors of the Oracle database include different languages and interfaces that allow programmers to access and manipulate the data in the database. Database programming features usually interest two groups: developers building Oracle-based applications that will be sold commercially, and IT organizations within companies that custom-develop applications unique to their businesses. The following sections describe the languages and interfaces supported by Oracle.This is the Title of the Book, eMatter Edition

SQL
The ANSI standard Structured Query Language (SQL) provides basic functions for data manipulation, transaction control, and record retrieval from the database. However, most end users interact with Oracle through applications that provide an interface that hides the underlying SQL and its complexity.
PL/SQL
Oracle’s PL/SQL, a procedural language extension to SQL, is commonly used to implement program logic

    1.) There have been several versions of SQL created in the last 26 years. In 1986, SQL-86 (SQL-87) was first published. In 1989, SQL-89 was a minor revision made to the original SQL. In 1992, SQL-92 (SQL2) was a major revision to its previous version. In 1999, SQL-99 (SQL3) added regular expression matching, recursive queries, triggers, non scalar types and some object oriented features.

In 2006, SQL-2006 defined ways in which SQL can be used in conjunction with XML and it defined ways of importing and storing XML data in an SQL database, manipulating it within the database and publishing both XML and conventional SQL-data in XML form. It also enables applications to integrate into their SQL code the use of XQuery. In 2008, SQL-2008 Legalized ORDER BY outside cursor definitions, added INSTEAD OF triggers, and added the TRUNCATE statement.

Realistically, making such a comparison is akin to discussing religion with friends. Each person will have their own biases based on their own experiences. Looking for an unbiased opinion is much like looking for the Holy Grail, every bit as speculative and subjective with the results jaundiced by the outlook of the reporter (Lim, 2002).…

    SQL was invented and developed by IBM in early 1970’s. IBM was able to demonstrate how to control relational databases using SQL. The SQL implemented by ORACLE CORPORATION is 100% compliant with the ANSI/ISO standard SQL data language. Oracle’s database language is SQL, which is used for storing and retrieving information. SQL allows users to access data in relational database management systems, such as Oracle, Sybase, Informix, Microsoft SQL Server, Access, and others, by allowing users to describe the data the user wishes to see. A table is a primary database object of SQL that is used to store data. A table holds data in the form of rows and columns…
