Used by Google, Linkedin, Amazon, Netflix, and Twitter, it is an easily accessible, high-performing system that is most commonly used for web-based applications. Let's start with a look at by far the most popular of the three - MySQL. Each has its own limitations and use cases, so let's take a look at when to use each to see which one might be the best fit for your next project. There are many dialects of SQL, the three most popular of which are SQLite, PostgreSQL, and MySQL. A relation is managed and/or queried using Structured Query Language (SQL). Each relation is then further organized into rows (tuples) and columns (attributes). RDBMSs use the relational model to store data in the form of tables (referred to as relations). There are lots of different types of DB management systems but the most widely used are Relational Database Management Systems (RDBMSs). SQLite is capable of creating in-memory databases that are very fast to work with.Database Management Systems (DBMS), in short, are collections of tools used to access and manipulate the data stored in a database. This brings many nice features like joining tables in different databases or copying data between databases in a single command. SQLite allows a single database connection to access multiple database files simultaneously. It means you can store any value in any column, regardless of the data type. In other words, all changes within a transaction take place completely or not at all even when an unexpected situation like application crash, power failure, or operating system crash occurs. It means all queries and changes are Atomic, Consistent, Isolated, and Durable. TransactionalĪll transactions in SQLite are fully ACID-compliant.
In addition, SQLite does not use any configuration files. There is no server process that needs to be configured, started, and stopped. Zero-configurationīecause of the serverless architecture, you don’t need to “install” SQLite before using it. If you want to develop an application that uses SQLite, you just need to drop these files into your project and compile it with your code.
Sql vs sqlite code#
The source code is available as a big sqlite3.c and its header file sqlite3.h.
Sql vs sqlite android#
This makes SQLite usable in any environment especially in embedded devices like iPhones, Android phones, game consoles, handheld media players, etc. SQLite is self-contained means it requires minimal support from the operating system or external library. The following diagram illustrates the SQLite server-less architecture: Self-Contained
The applications interact with the SQLite database read and write directly from the database files stored on disk.
SQLite database is integrated with the application that accesses the database. The following diagram illustrates the RDBMS client/server architecture: This is called client/server architecture. The applications that want to access the database server use TCP/IP protocol to send and receive requests. Normally, an RDBMS such as MySQL, PostgreSQL, etc., requires a separate server process to operate. SQLite has the following noticeable features: self-contained, serverless, zero-configuration, transactional. The lite in SQLite means lightweight in terms of setup, database administration, and required resources.
Sql vs sqlite software#
SQLite is a software library that provides a relational database management system. Summary: This tutorial gives you a brief overview of SQLite and the SQLite’s distinctive features that make SQLite the most widely deployed SQL database engine.
