![]() ![]() On the contrary, SQLite is limited to single-user access, making scalability difficult. ![]() The server layer simplifies the server’s capabilities without updating the client side. MySQL’s server-client architecture is well-designed for scalability and large databases. These are more generic than data types and can take one of the following storage classes: NULL, INTEGER, TEXT, BLOB, and REAL. Instead of data types, SQLite uses storage classes for data. Additionally, MySQL has backward compatibility for common static types. For example, if you create a table of the integer type at the creation time, you can store any data type in this column as the type is associated with the value itself, not its container. While most database engines still use static types for string data, SQLite uses dynamic types for storing data - the value stored in a column determines the column datatype. Like most DBMSes, MySQL uses static types for data storage, meaning that you must define column datatypes at the time of table creation. The back end stores the tables on the disk in a B-tree implementation. In contrast, SQLite is a serverless DBMS that compiles the SQL into bytecode, which is then executed using a virtual machine. Finally, the storage layer is responsible for storing the data tables. The server layer processes the commands’ logic, creating a new thread for each request. The client layer handles user queries and commands using GUI or CLI. MySQL follows a multi-layer, server-client architecture that consists of a client, server, and storage. While MySQL and SQLite are both open-source RDBMSes, they have very different architectures and use cases. You can also read more about MySQL on our blog. As Oracle maintains MySQL, you can find tutorials, certificates, and support on the MySQL website. Millions of tutorials are available on the Internet to help you learn MySQL, and you can find an answer to almost any question or problem online. Moreover, MySQL is platform-independent, which means it can run on any OS and is compatible with different programming languages like Python, Java, and C++.īeing the most popular DBMS comes with another advantage: its community. It also offers a command-line interface (CLI) called mysqladmin for managing usable data. MySQL also comes with a built-in graphical user interface (GUI) called MySQL Workbench for accessing the data. The server handles commands like retrieving, manipulating, and adding data using a structured query language (SQL). Unlike SQLite, MySQL follows the client-server architecture and requires a server to run. What Is MySQL?įast, reliable, and easy to learn, most applications use MySQL as their preferred DBMS. These features make SQLite suitable for the Internet of Things ( IoT), embedded applications, and desktop applications. In addition, the serverless SQLite doesn’t require installation or configuration, making it self-contained and less dependent on the operating system (OS). Most databases require a server process, but SQLite is serverless, meaning the application can read and write data directly without client-server architecture. SQLite, as the name implies, is lightweight regarding setup, administration, and storage. This foreign key references a specific row in the “department” table. Instead, you can add a column with a reference - the foreign key - to the department in the employee table. There’s no need to add the department name to the employee table. For example, suppose you have a database of employees in a company. The primary key is the unique value that identifies each database row, while you can use the foreign key to reference other tables. There are two types of keys in RDBMS: the primary key and the foreign key. That’s why these DBMSes are called relational. Each table consists of rows that contain a unique value called a key, which is used to relate the tables. RDBMSes store data in multiple two-dimensional tables instead of one big table. SQLite is an open-source relational database management system (RDBMS). Most of these types deal with data in a hierarchical model, organized in a tree-like architecture, and connected through links. Some open-source databases operate on an available-source basis, making them more flexible to match your application’s needs.Īs mentioned before, DBMSes consist of four main types. ![]()
