This article mainly shows you "what is the difference between sqlite and mysql". It is easy to understand and clear. I hope it can help you solve your doubts. Let the editor lead you to study and learn the article "what is the difference between sqlite and mysql".

Differences: 1. Compared with MySQL, SQLite supports fewer data types. 2. The portability of SQLite is good, but MySQL is poor. 3. MySQL has a well-constructed user management system, but SQLite does not. 4. SQLite has no built-in authentication mechanism, while MySQL has high security.

What's the difference between sqlite and mysql?

Databases are the core part of any website or development design, and SQLite and MySQL are mainstream open source databases. In this article, we will analyze the essential difference between the two.

The database management system is also known as DBMS, often referred to as RDBMS. RDBMS stands for a relational database management system. At the most basic level, all databases are used to manage, maintain, and manipulate data.

The data model can be one of the following:

NoSQL-an unstructured, still developing model

Relational DBMS-A structured and more commonly used model

What is a database management system?

DBMS is software that interacts with databases and helps to perform a number of operations on the databases it manages, some of which are:

Manage access to the database

Run a SQL query

Write data to the database

Update the database

Delete data from the database

In most cases, databases and DBMS can be used interchangeably. However, a database is a collection of stored data, and DBMS is the software used to access the database.

Each DBMS has an underlying model that determines the structure of the database and how to retrieve the data. Relational DBMS uses the Relational data model, where the data is organized in tabular form. Each table has a set of properties or columns, and each row, also known as a tuple, has a relationship. For this reason, structuralization is called RDBMS.

To use RDBMS, you must use SQL or a structured query language, and each RDBMS has a different syntax.

The difference between SQLite and MySQL

SQLite and MySQL are both open source RDBMS

Architectural differences-SQLite versus MySQL

SQLite is an open source project available in the public domain

MySQL is an open source project owned by Oracle

SQLite is a serverless database that is self-contained. This is also known as an embedded database, which means that the database engine runs as part of the application.

On the other hand, MySQL needs to run the server, and MySQL will require client and server architectures to interact over the network.

Data type support-SQLite and MySQL

SQLite supports the following data types: Blob,Integer,Null,Text,Real.

MySQL supports the data types mentioned below:

Tinyint, Smallint, Mediumint, Int, Bigint, Double, Float, Real, Decimal, Double precision, Numeric, Timestamp, Date, Datetime, Char, Varchar, Year, Tinytext, Tinyblob, Blob, Text, MediumBlob, MediumText, Enum, Set, Longblob, Longtext.

MySQL is more flexible in terms of data types.

Storage and portability-SQLite and MySQL

The size of the SQLite library is about 250 KB, while the MySQL server is about 600 MB. SQLite stores information directly in a single file, making it easy to copy. No configuration is required, and the process can be done with minimal support.

Before you can copy or export MySQL, you need to compress it into a single file. For larger databases, this can be a time-consuming activity.

Multiple access and scalability-SQLite and MySQL

SQLite does not have any specific user management capabilities, so it is not suitable for multi-user access. MySQL has a well-constructed user management system that can handle multiple users and grant different levels of permissions.

SQLite is suitable for smaller databases, and as the database grows, the memory requirements become larger when using SQLite. When using SQLite, performance tuning is more difficult. In contrast, MySQL is easy to extend and can easily handle larger databases.

Security and ease of installation-SQLite and MySQL

SQLite has no built-in authentication mechanism, and anyone can access database files. However, MySQL comes with many built-in security features. This includes using usernames, passwords, and SSH for authentication.

SQLite does not require much configuration and is easy to set up. MySQL requires more configuration than SQLite.

Pros and cons-SQLite and MySQL

Advantages of SQLite:

File-based, easy to set up and use

Suitable for basic development and testing

Easy to carry

Make minor changes using standard SQL syntax

Easy to use

Disadvantages of SQLite:

Lack of user management and security functions

Not easy to expand

Not suitable for large databases

Cannot be customized

Advantages of MySQL:

Easy to use

Provides a number of database-related features

Good security function

Easy to expand and suitable for large databases

Provide good speed and performance

Provide good user management and multiple access control

Disadvantages of MySQL:

Some technical expertise is required to set up

Compared with traditional SQL, the syntax is slightly different.
