Introduction to SQL: Database Lecture 1 Outline

SQL Basics

• SQL stands for Structured Query Language.
• SQL became a standard of the American National Standards Institute (ANSI) in 1986.

SQL Schema Management

• The DROP DATABASE statement is used to drop an existing database in SQL schema.
• The syntax to create a new database in SQL is CREATE DATABASE database_name;.
• The USE statement is used to select an existing database in SQL schema before starting operations.

RDBMS

• RDBMS stands for Relational Database Management System.

Database Concepts

• A table in SQL consists of rows and columns that store and organize data.
• SQL Server offers two categories of data types: system data types and user-defined data types.
• SQL data types define the type of data a column can hold in a database.

Database Applications

• To build a website that shows data from a database, a database management system, a web server, and a programming language are needed.
• SQL plays a crucial role in building a website that shows data from a database by managing and providing access to the data.

Data and Information

• Data refers to raw, unorganized facts and figures.
• Information refers to processed data, organized, structured, or presented in a given context to make it useful.
• A database consists of an organized collection of data, typically in a digital form.

Database Management

• A Database Management System (DBMS) is a software system that allows defining, creating, maintaining, and manipulating databases.
• The primary function of a database is to store, organize, and provide access to data.

Advanced Database Concepts

• A geographic information system (GIS) database stores and analyzes maps, weather data, and satellite images.
• Manufacturing sector can benefit from using a database to manage production, inventory, orders, and supply chain.
• OLAP stands for Online Analytical Processing in the context of databases.
• The feature that allows more than one person to access the same database at the same time is called concurrency control.
• Data can be stored in a database in various formats, including text, images, and audio.

Real-Time Databases

• The primary function of a real-time and active database technology is to support high-performance, event-driven applications.

Choosing between a Database and a Spreadsheet

• A database should be used instead of a spreadsheet when managing large amounts of data, especially when data needs to be shared, accessed, and updated by multiple users.
