SQLite - what is that and why it is important to know
SQLite is a popular database management system. One of its significant features is its lightweight nature - the database system is based on a single file. Due to this, it is often used where an easy method of storing local data is needed. In this article, we'll briefly present the main features and applications of the SQLite database.
Key Features of SQLite
Traditional SQL-based databases require a special server to function. When wanting to store a small amount of data locally, such a server introduces many complications and adds unnecessary "weight" to our application.
One of the huge advantages of SQLite is its "lightweight" nature. The entire database is contained in a single file and can be moved freely - just like any other file. This file can be easily copied, transmitted, etc.
Another advantage is that SQLite offers most of the capabilities known from traditional server-based databases. Therefore, in such a database, you have access to tables, keys, relationships, and functions. Queries are written using traditional and widely known SQL syntax, so there's no need to learn a new query language.
Where SQLite is Used
SQLite databases are used where a lightweight database is needed for local data storage. A good example is mobile applications: phones often have limited space and performance. In such situations, SQLite can showcase its advantages. This type of database is used, for instance, to store application settings or user data.
SQLite is often used in embedded systems, various electronic devices. Here, there are even greater performance limitations than on phones, and SQLite, as a simple database in the form of a small file, is often the only reasonable way to store data.
There are many more examples of using this database. Numerous desktop applications, some web browsers, and even web applications use it.
Once again, let's emphasize the main feature of SQLite - it's a simple, lightweight database in the form of a single file. If your application needs to store data locally and you don't want the cost of implementing a heavy server database, then SQLite can be a very good choice.
How to Start Working with SQLite
A detailed discussion of working with SQLite would go beyond the scope of this modest article. It's worth mentioning that many popular programming languages (C++, Python, Java, etc.) have libraries that enable working with the SQLite database. Therefore, you can easily integrate such a database into your applications. Check the documentation of the language or framework you're using. There's a good chance it has a ready-to-use integration with SQLite.
Summary
An SQLite-type database is a good way to store local application data (e.g., settings, user preferences, etc.). It's lightweight, efficient, and easy to implement. SQLite can be seamlessly integrated with most popular languages, libraries, and frameworks.
