In this article, we will cover the comparison between the SQLite, and MySQL databases, basic knowledge about them, their benefits and differences.
Deciding where to store sensitive transactional data becomes crucial when we want free or low-cost database management software. That why it is important to find a good database management system that includes features like the ones from SQL Server, Oracle, and so on.
For the previously given criteria, we will analyze two specific databases, SQLite and MySQL. Both databases share the fact of being free and open-source, but each one has unique features that we will cover next.
SQLite or MySQL?
Reliable, portable, ‘serverless’ database – since it does not need a server process to communicate; that is how SQLite is presented. MySQL is considered as a quick, reliable and has an advance coverage for the standard SQL. Let us check some of the main points to compare between SQLite and MySQL:
|This database supports these data types: BLOB, REAL, TEXT, INTEGER and NULL.
|This database supports these data types: BIT, SMALLINT, TINYINT, INT (INTEGER), MEDIUMINT, BIGINT, FLOAT, DOUBLE PRECISION, DECIMAL, REAL, DOUBLE, NUMERIC, FIXED, BOOLEAN, DATE, YEAR, TIME, DATETIME, TIMESTAMP, BINARY, VARCHAR, VARBINARY, TINYTEXT, TEXT, MEDIUMTEXT, LONGTEXT, SET, CHAR, TINYBLOB, MEDIUMBLOB, BLOB, LONG, BLOB, ENUM|
|Low-security control over application bugs, multiple access by users, and because it is a serverless database, all processes access directly to the database disk file, which generates general locking and a limited concurrency.||Uses several security levels, such as the root password, eliminating test databases and unknown users accessing the database. This database supports management at a user level, creating and granting different access levels, giving privileges to specific objects.|
|Components such as the SQLite library do not need much disk space, which can be less than 1MB and does not have any other dependence on external applications to work.||MySQL installation process needs at least 800 MB (service manager for Windows x86 for 64 bits), not including the minimum requirements for the additional components the MySQL needs.|
|Data storage in one file, easily shared by file transfer or removable devices.||Data storage in different files, and has different replication types.|
|Storage data is contained in one file; changes over the database are made one at a time.||Storage data is contained in different files, and it has user management access, multiple processes can change data in the database at a time.|
|Based on a SQL transactional database engine, it contains almost all of the SQL functionality||SQL limitations, due to speed improvement; functions such as FULL JOIN are not supported.|
Table 1. Comparison between SQLite vs MySQL
Let us check in different scenarios, which of the two databases discussed previously would be suggested:
|Scenario||Applied for SQLite||Applied for MySQL|
|Network access needed||No||Yes|
|Quick increase of data processing||No||Yes|
|Low to medium data storage||Yes||Yes|
Table 2. Given scenarios between SQLite vs MySQL
Keep in mind that we are comparing only two databases and can be better options (free or commercial databases), such as Oracle, Microsoft SQL Server or PostgreSQL. These advanced databases were designed for bigger data storage and to work with llarger transactional process.
