What is MySQL?

S  It is the world’s most commonly used RDBMS

S  It is named after developer Michael Widenius; daughter, MY

S  Its source code is available under the terms of the GNU General Public License.

S  MySQL was owned and sponsored by a single for-profit firm, the Swedish company MySQL AB, now owned by Oracle Corporation

S  MySQL is used in high-profile, large-scale World Wide Web products, including Wikipedia, Google, Facebook and Twitter.

History

S  Originally developed by Michael Widenius and David Axmark in 1994

S  First release on 23rd of May 1995

S  Windows version was released in 1998

S  …

S  MySQL server 5.5 was released in December 2010

Uses

S  It is the most popular choice of database for use in web applications

S  It is a central component of the widely used LAMP open source web application software stack (LAMP: Linux, Apache, MySQL, Perl/PHP/Python)

Platforms and interfaces

S  MySQL is written in C and C++

S  It works on many different system platforms, including Linux, Mac OS X, Solaris, etc.

S  Some programming languages include libraries for accessing MySQL databases. These include MySQL Connector/Net for integration with Microsoft’s Visual Studio and JDBC driver for Java

Graphical User Interface

S  MySQL has no GUI tools to administer the databases or manage the data contained

S  Official MySQL Workbench enables users to graphically administer MySQL databases and visually design database structures

S  MySQL Workbench allows the users to manage the following: S  Database design & modeling S  SQL Development S  Database Administration

MySQL Demo

S The video is a demonstration done on MySQL on campus

Syntax

Point of Comparison Similarity or difference

DDL Almost the same

DML The same in everything except for the outer join

DCL The same

Why MySQL?

MYSQL has proven itself to be fast, reliable and cost effective to

other competitors such as MS SQL Server and Oracle

Why MySQL?

Open Source

S  It is free and developers can amend its code to suit their requirements, which makes MYSQL highly customizable.

Fast Development

S  New modules are constantly being developed for integration with MYSQL. This presents a wider and faster circle of patches, upgrades and fixes available.

Scalability

S  MySQL supports the capacity to handle deeply embedded application running massive data and holding terabytes of information.

Flexibility

S  compatible with Windows, Linux, OS2 and Solaris. It also includes APIs for integration with C, C++, PHP, Java, Perl, Python, Tcl, Ruby, etc.

Performance

S  A unique storage-engine architecture allows server configuration according to the application type - whether high-speed transactional processing system or high-volume web site servicing millions of queries a day.

Availability

S  According to a MS Case Study: Stratus Technologies, SQL Server delivers “six nines”. That is 99.9999% uptime availability.

S  High availability options vary

Robust Transactional Support

S  Complete ACID (atomic, consistent, isolated, durable) transaction support, distributed transaction capability, and multi-version transaction support where readers never block writers and vice-versa.

S  Full data integrity is also assured through server-enforced referential integrity, specialized transaction isolation levels, and instant deadlock detection.

Security

S  All access passwords are stored in an encrypted format and unauthorized accesses are restricted. It also encrypts the transactions so eavesdroppers (=listeners/spies) and data harvest tools cannot replicate or regenerate the database transactions once they are processed.

Favorable for…

S  Small Businesses: free, easy to learn and operate

S  High traffic websites: high performance, fast data insert capability, support for web functions

S  Data Warehouse: scales up into the terabyte range featuring main memory tables, B-tree and hash indexes and compressed archive tables that reduce storage requirements by up to 80%
