MYSQL : UNLOCKING THE
POWER OF DATABASE
MANAGEMENT

A database is an organized collection of structured
information, or data, typically stored electronically in a
computer system. A database is usually controlled by
a database management system (DBMS). Together,
the data and the DBMS, along with the applications
that are associated with them, are referred to as a
database system, often shortened to just database.
Data within the most common types of databases in
operation today is typically modeled in rows and
columns in a series of tables to make processing and
data querying efficient. The data can then be easily
accessed, managed, modified, updated, controlled,
and organized. Most databases use structured query
language (SQL) for writing and querying data.
What Is a Database?

A relational database management system
(RDBMS) is, as the name suggests, software that
manages a relational database. It is a set of
smaller programs designed to work together,
allowing the developer to store, access, and modify
data in tables, transparently and without having to
know where the data is physically stored on disk.
You can interact with any relational database
management system by using the SQL
programming language. SQL stands for “Structured
Query Language”, which allows you to interrogate
structured data stored in tables.

RDBMS Terminology
Database - A database is a collection of tables, with related data.
Table - A table is a matrix with data. A table in a database looks like a simple
spreadsheet.
Row - A row (= tuple, entry or record) is a group of related data, for example the
data of one subscription.
Redundancy - Storing data twice, redundantly to make the system faster.
Column - One column (data element) contains data of one and the same kind, for
example the column postcode.

MYSQL 6
RDBMS Terminology
Primary Key - A primary key is unique. A key value can not occur
twice in one table. With a key, you can only find one row.
Foreign Key - A foreign key is the linking pin between two tables.
Index - An index in a database resembles an index at the back of a book.
Referential Integrity - Referential Integrity makes sure that a foreign key value
always points to an existing row.
Compound Key - A compound key (composite key) is a key that consists of multiple
columns, because one column is not sufficiently unique.

• MySQL is a relational database management system that
was first released in 1995.
• It was developed by Swedish co-founders Michael
Widenius and Allan Larsson and was initially released as
an open-source database.
• Over the years, MySQL has become one of the most
popular databases for web applications due to its ease of
use and stability.
• In 2008, MySQL was acquired by Sun Microsystems,
which was later acquired by Oracle Corporation in 2010.
• Despite its corporate ownership, MySQL remains a
popular open-source database and is widely used by
developers and organizations of all sizes.

• SQL support for data management and organization.
• Scalability for handling large amounts of data.
• Cross-platform compatibility, running on various operating
systems.
• Security features, such as user authentication and data
encryption.
• High performance with fast query processing and data
retrieval.
• Widely supported by the community, with many tools and
libraries available.
• Data backup and recovery features for data integrity and
availability.

• Fast query processing: MySQL designed for fast query
processing and data retrieval
• Indexing: It’s uses indexes to speed up data retrieval and
improve performance.
• Optimization: It’s provides various optimization techniques, such
as query caching and table optimization, to improve performance.
• Concurrent access: It’s is capable of handling multiple concurrent
users, allowing for efficient and simultaneous data access.
• Memory usage: It’s is designed to use memory efficiently,
reducing the load on disk I/O and improving performance.
• Scalability: It’s can scale to accommodate growing data needs,
ensuring high performance as the amount of data grows.
• Configurability: It’s is highly configurable, allowing users to adjust
settings to meet the performance needs of their specific
applications.

• MySQL vs. PostgreSQL: Both MySQL and PostgreSQL are
open-source relational databases, but PostgreSQL is often
considered to be more feature-rich and capable of handling
complex queries and data structures.
• MySQL vs. Microsoft SQL Server: SQL Server is a
proprietary database from Microsoft that is widely used in
enterprise environments. It offers more advanced features,
such as support for in-memory databases and sophisticated
security features.
• MySQL vs. Oracle Database: Oracle Database is a
proprietary database from Oracle Corporation that is widely
used in enterprise environments. It offers advanced features,
such as real-application clusters, data warehousing, and
advanced security features.
• MySQL vs. MongoDB: MongoDB is a NoSQL document-
oriented database that is designed for scalability and flexible
data management. It offers features such as automatic
sharding and indexing, which are not typically found in

Today, MySQL is one of the most popular
and widely used SQL databases. It is also
one of the most used databases in Web
Applications. Some of the world’s largest
Web-Scale applications (e.g., Facebook,
Uber) uses MySQL.
MySQL Community Edition is the most widely
used free database in the industry. Also, its
commercial version is used extensively in the
industry.
The most prominent database ranking site DB-
Engines ranked MySQL as the second-highest
ranked database, just behind Oracle:
