![]() These catalogs (columns, tables, databases and etc.) can be modified very easily by the user. PostgreSQL stores much more information in its catalogs, unlike MySQL or SQLite. PostgreSQL AdvantagesĮxtensibility: PostgreSQL is extensible because its operation is catalog-driven. PostgreSQL is less used than MySQL or SQLite and is maintained by the PostgreSQL Global Development Group. Database types offered by PostgreSQL are bigint, integer, real, date, interval, and many more sorted as Numeric Types, Character Types, Date and Time Types, Geometric Types, Network address types and etc, viewable at the PostgreSQL official documentation. PostgreSQL can handle multiple tasks at the same time without reading locks which ensures isolation and consistency of its transactions. ![]() It is a highly compliant and extensible database, and the most advanced compared with MySQL or SQLite database systems. PostgreSQL or better Postgres, is an open-source relational database management system written in C and C++. SQLite is not supporting replication instead of MySQL and PostgreSQL. This means that there are no users, with permissions to the database and only one process can write into the database. The disadvantages of SQLite are related to the users, limitations with the changes in the database, and sometimes with the security. ![]() User Friendly: SQLite is running without a server process, so you do not need to start, stop or restart the service. Portability: SQLite stores the data into a single file that can be located anywhere on the server, and can be transferred very easily from one to another server, or device. Also, SQLite can keep the application alive so it can not face any downtime. SQLite only requires around 650KB of disk space and has a small footprint.Ĭaching: SQLite can cache data from the server locally and reduce the latency for queries. Small Size: SQLite does not require too much space or dependencies before its installation. SQLite is maintained by a group of developers. Database types offered by SQLite are null, integer, real, text, blob, datetime and etc. This additionally tells us that the SQLite is running directly and there is no need for installation and setup at all. Unlike other relational database management systems that are implemented as s server processes, SQLite is a “serverless” database and allows any process to read and write to the database disk directly. SQLite is an open-source relational management database system written in C and the most used database engine by the operating systems, embedded systems, web browsers and etc. The other disadvantage is that MySQL has slow concurrent read-writes. Also, MySQL queries are limited, and they should be smaller. MySQL DisadvantagesĬompared to the advantages of MySQL, the disadvantages are very rare and are related to some limits, sometimes with stability and scaling. With the above advantages, the MySQL database system is very popular, easy to install, and easy to use. ![]() You won’t face downtime of your website with this setup. This is due to better reliability, accessibility, availability, and 100% uptime of the database service. We can replicate master to slave and master to master. Replication: The third advantage is the replication that MySQL offers. MySQL offers a script called mysql_secure_installation which can be set the password of the root user, removed the anonymous user, test databases and etc. Security: The second advantage which is very important is security. Speed: As we said in the previous paragraph, the main purpose of the MySQL developers was to work on the speed, we can confirm that the fastest database management system at the moment is MySQL. MySQL is open-source, written in C and C++, and is developed and maintained by the Oracle Corporation. The main purpose of the developers was to make MySQL a fast and reliable database management system. Database types offered by MySQL are tinyint, smallint, mediumint, int, bigint, float, double, datetime, char, and many more, which can be viewed on the official documentation of MySQL in three categories: numeric types, date types, and string types. MySQL has a huge number of developers and very good documentation which is very helpful for the new users that number is increasing on daily basis. MySQL as a relational management database system is the most popular since, the first database rankings around 10 years ago. ![]()
