Study Notes

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.
