...MET CS 669 Database Design and Implementation for Business SQL Lab 4 Instructions: Procedural SQL Objective The objective of this lab is to teach you how to develop and use basic stored procedures and triggers the procedural language of your chosen DBMS. Prerequisites Before attempting this lab, it is best to read the textbook and lecture material covering the objectives listed above. While this lab shows you how to create and use these constructs in SQL, the lab does not explain in full the theory behind the constructs, as does the lecture and textbook. The second section in this lab builds on Lab 3. It is best to complete Lab 3 first before completing the second section in this lab. Required Software The examples in this lab will execute in modern versions of Oracle and Microsoft SQL Server as is. Note that the first section in this lab has syntax specific to each DBMS, and you will need to complete the version for the DBMS you are using. If you are using a different RDBMS, you may need to modify the SQL for successful execution. Saving Your Data If you choose to perform portions of the assignment in different sittings, it is important to commit your data at the end of each session. This way, you will be sure to make permanent any data changes you have made in your curent session, so that you can resume working without issue in your next session. To do so, simply issue this command: COMMIT; Data changes in one session will only be visible only in that session...

...with Oracle This is a small tutorial for Oracle 8i to teach the basics of SQL. Follow the steps and Oracle will be fun for you. Step 1: Click the Start button, select Programs, then select SecureCRT 3.x. This will open up the quickconnect dialog box of SecureCRT. Select 1. Protocol as: SSH2 2. Hostname: babbage2.cs.iit.edu 3. SSH Server: Standard As depicted in figure below. On clicking connect at this point will bring up another dialog. Select “Accept and Save” to bring up a window asking username and password for Unix. Upon entering valid username and password, you should now see unix bash prompt. Now type just “sqlplus” at bash prompt to connect to Oracle. It will prompt for username and password for oracle. Upon entering valid username and password, you should now see SQL prompt as: SQL> 1 You are now connected to oracle through SQLPlus client installed on Unix Machine (babbage2.cs.iit.edu). Have fun. Also, if you want to find more information on installing oracle on your personal machine, go to www.oracle.com. Remember at SQL> prompt, after every sql command, don’t forget to put a semicolon(;). A SQL statement is the statement that complies with the syntax rule of SQL. A list of SQL statements such as create, delete, insert, select, and update will be frequently used. The SQL*PLUS commands are the auxiliary set of commands that may be only recognized by ORACLE SQL*PLUS. Frequently used commands in ORACLE SQL*PLUS interface are clear, describe, edit, get, help, list...

...reality in a way that supports processes requiring information. For example, modelling the availability of rooms in hotels in a way that supports finding a hotel with vacancies. Database management systems (DBMSs) are computer software applications that interact with the user, other applications, and the database itself to capture and analyze data. A general-purpose DBMS is designed to allow the definition, creation, querying, update, and administration of databases. Well-known DBMSs include MySQL, PostgreSQL,Microsoft SQL Server, Oracle, SAP and IBM DB2. A database is not generally portable across different DBMSs, but different DBMSs can interoperate by using standards such asSQL and ODBC or JDBC to allow a single application to work with more than one DBMS. Database management systems are often classified according to the database modelthat they support; the most popular database systems since the 1980s have all supported the relational model as represented by the SQL language. Sometims a DBMS is loosely referred to as a "database". database is a collection of information that is organized so that it can easily be accessed, managed, and updated. In one view, databases can be classified according to types of content: bibliographic, full-text, numeric, and images. In computing, databases are sometimes classified according to their organizational approach. The most prevalent approach is therelational database, a tabular database in which data is defined so that it can be reorganized...

...How To Become A Web Developer How To Become A Web Developer. Are you interested in becoming a web developer? If so, you’ve found the right place for information. Learn more about this exciting career path in this article. What Is A Web Developer? First of all, let’s go over what a web developer is: A web developer is someone who programs web sites. They write the code, whether it is to display a web page using HTML or to perform complex functions using PHP or another language. They may also need to access a database or other systems in order for the web page to work correctly. As you might have realised, there are many different languages that a web developer can use. HTML, CSS, JavaScript, PHP, .NET, SQL, and many others. This makes them versatile but also means they need to learn a lot more than other developers. Web developers may also need to learn design skills, depending on the kind of work they want to do. There is a whole different area of developing web sites related to the design work, which is usually done by Web Designers, but for some small projects or clients, the web developer often does that work as well. Hopefully that has cleared it up. Let’s get into what you need to do to become a web developer. You Don’t Necessarily Need a Degree Web development is one of the few IT roles that I’ve noticed that you don’t actually need a degree for. This might be a good thing for many of you, as I’ve had a lot of questions about getting into IT without getting a...

INTRODUCTION Pronounced “S-Q-L” by some and “sequel” by others, SQL has become the de facto standard language for creating and querying relational databases. (Can the next standard be the sequel to SQL?) The primary purpose of this chapter is to introduce SQL, the most common language for relational systems. It has been accepted as a U.S. standard by the American National Standards Institute (ANSI) and is a Federal Information Processing Standard (FIPS). It is also an international standard recognized by the International Organization for Standardization (ISO). ANSI has accredited the International Committee for Information Technology Standards (INCITS) as a standards development organization; INCITS is working on the next version of the SQL standard...
