Intro to Relational Database Management Systems - Chapter Summary
In this chapter, you'll find a helpful introduction to relational database management systems you can use to refresh your knowledge of these subjects. Our lessons cover the elements and advantages of a relational database, database applications and different types of database programs. These lessons work equally well if you're new to these topics or want a quick refresher of information you already know. The quizzes along with each lesson provide a quick assessment you can use to guide your study more wisely. Help from one of our experts is available in the Dashboard should you need it. After completing this chapter, you should be able to:
- Explain how to design a database schema
- Give an example of SQL normalization
- Outline the types of normal form in DBMS
- Provide examples of first normal form and third normal form in DBMS
- Define database query and its tools
- Identify DDL, DCL and DML in MySQL
- Discuss basic SQL commands in database management systems
- Understand how to install Oracle Database Express Edition for database programming
- Install MySQL and SQL Server Express Edition for database programming
1. What is a Relational Database? - Elements, Design & Advantages
The relational database is the most widely used type of database management system. Learn how the relational database organizes data using tables, keys and associations.
2. What is a Database Application?
From social media to your bank, practically everything you do depends on a database. Database applications are used to access those databases in an efficient and secure way.
3. Database Programs: Types & Examples
In this lesson you'll learn about databases and database programs. We'll look at examples of various types of database programs and highlight their differences in application.
4. How to Design a Database Schema
Just as in construction, a solid database needs a blueprint. Database schemas are blueprints for databases. In this lesson, we will discuss how to design and create a database schema.
5. SQL Normalization: Example & Rules
The amount of information we capture these days is staggering, so removing duplication is important. In this lesson, we'll take a look at SQL, normalization, and the rules associated with them.
6. What is Normal Form in DBMS? - Types & Examples
This lesson explains the concept of correcting table structures in order to minimize database anomalies through a process called normalization. The normal process consists of multiple steps, called normal forms, each ensuring the elimination of the various types of anomalies.
7. First Normal Form in DBMS with Examples
First Normal Form might sound like the place to be if you're a database. But being first has its drawbacks. This lesson will define first normal form and provide real-world examples.
8. Third Normal Form in DBMS with Examples
Normalization in databases help organize tables and keeps records clean. This lesson will cover the third normal form of database normalization which, through the extension of the second normal form (2NF), further reduces dependencies within the data.
9. Database Query: Definition & Tools
This lesson will cover the concept of a database query. Database queries will be defined, and some basic examples will be explained. An example of query design using the Microsoft Access tool is described.
10. What are DDL, DML and DCL in MySQL?
Information comes us at from many directions. Databases help us make sense of the information in our world. In this lesson, we'll take a look at a specific example, MySQL, and the commands that can be employed to make sense of data.
11. Basic SQL Commands in Database Management Systems (DBMS)
Basic SQL commands allow the user to achieve significant manipulation of data in the database. The database management system is the software that allows access to the database and to apply SQL commands to manage data.
