Oracle Install PL/SQL Primer Tutorial
Oracle databases are great in design and in their range of software tools. The SQL is great and their command line tool SQL*Plus makes the creation of procedures around a job, especially reporting type jobs, very easy. Oracle SQL Developer is a great user-friendly application to enhance the Oracle suite of software to help maintain Oracle databases. You can do reports straight from a view of the database with ordinary SQL and if it asks for more drilling down, Oracle has this great procedural SQL language called PL/SQL. For fast speeds as well, add Pro*C (Pro*C++ (more information) these days) into the mix. Pro*C(++) embeds SQL code into your C(++) code making use of cursors and other database smarts. Oracle is such a solid database, different arrangements of which work with large and small amounts of computing “grunt”. We discuss Pro*C in a primer tutorial Oracle Pro*C Cursor Primer Tutorial.
This tutorial shows you a Windows 32 bit Oracle install, but Unix or Linux are also great operating environments for Oracle databases and I particularly like Korn Shell as a scripting language of choice to supervise all the Oracle work in Unix. It can call SQL*Plus and/or another script and/or Pro*C compiled code and/or PL/SQL and/or Python and/or other types of compiled code (eg. C executables).
So if you combine these two it is easy to create robust procedures that run really well.
Below is a bit of Oracle history.
Oracle Corporation is an American multinational computer technology corporation headquartered in Redwood City, California, The United States. The company specializes in developing and marketing computer hardware systems and enterprise software products – particularly its own brands of database management systems. Oracle is the third-largest software maker by revenue, after Microsoft and IBM.[3]
The company also builds tools for database development and systems of middle-tier software, enterprise resource planning software (ERP), customer relationship management software (CRM) and supply chain management (SCM) software.
Larry Ellison, a co-founder of Oracle Corporation, has served as Oracle’s CEO throughout its history. He also served as the Chairman of the Board until his replacement by Jeffrey O. Henley in 2004. On August 22, 2008, the Associated Press ranked Ellison as the top-paid chief executive in the world.[4][5]
Let’s see Oracle Database and Client install for Windows 32bit environment within a tutorial which also shows “Hello World” in SQL and PL/SQL and a SELECT piece of sql to show all column names in existing tables, all using the wonderful SQL*Plus (command line usage). If you hate command line usage (please don’t be scared, as it is always good to know “what lies beneath” … do do do do do do do do Vs ?!) you can see in the downloads area Oracle SQL Developer which is a great user-friendly interface to Oracle, and which we will do another tutorial about, one day.
