Database Basics Tutorial Videos344

Introduction

Databases are a fundamental component of modern computing systems. They allow us to store, manage, and retrieve data in an efficient and organized manner. In this tutorial, we will provide an overview of the basic concepts of databases, including their structure, types, and operations. We will also provide links to a series of video tutorials that will walk you through the basics of database management.

What is a Database?

A database is a collection of structured data that is stored in a computer system. The data is typically organized into tables, which are made up of rows and columns. Each row represents a single record, while each column represents a different attribute of the record. For example, a customer database might have a table that contains the names, addresses, and phone numbers of customers.

Types of Databases

There are two main types of databases: relational databases and NoSQL databases. Relational databases are based on the relational model, which uses tables and relationships to organize data. NoSQL databases are non-relational databases that do not use tables or relationships. Instead, they store data in a variety of flexible formats, such as documents, key-value pairs, or graphs.

Database Operations

There are four basic database operations: create, read, update, and delete (CRUD). These operations allow us to interact with the data in a database. The create operation allows us to create new records in a table. The read operation allows us to retrieve records from a table. The update operation allows us to modify records in a table. The delete operation allows us to delete records from a table.

Database Management Systems (DBMSs)

A database management system (DBMS) is a software program that allows us to create, manage, and access databases. DBMSs provide a variety of features to make it easier to work with databases, such as data definition language (DDL), data manipulation language (DML), and query language. DDL allows us to create and modify tables and other database objects. DML allows us to insert, update, and delete data from tables. Query language allows us to retrieve data from tables.
