Database is a warehouse for storing, managing and organizing data, which plays a vital role in embedded development . In embedded training, there are many kinds of databases that we can learn to use, and each database will show a different aspect, so what kind of databases can we use in embedded system development training? Huaqing Vision Embedded Academy will give you a detailed introduction.
The first type: MySQL for embedded development
This is a relational database management system with the characteristics of small size, fast speed, and low cost, especially its source code development characteristics. Many websites choose MySQL database in order to reduce development costs, and it is widely used.
The second type: Berkeley for embedded development
The source code of this database is open source, and it is an embedded database management system, which can achieve high performance when used in the management service of application programs. In the process of programming, you only need to call some simple API functions to access the database and manage the database effectively. It is different from commonly used database management systems such as MySQL and Oracle. In BerkeleyDB, there is no concept of database server. Through the function library embedded in the program, the application does not need to establish a network connection in the database service in advance, and directly completes the storage, query, modification and deletion of data.
The third type: mSQL for embedded development mSQL is a single-user data management system. It is a development and application system often used by users on the Internet. mSQL is a small relational data manager that occupies very little system resources and cannot fully support certain standard SQL functions. It also lacks many ANSISQL features. It can be said that it basically does not support all nested SQL statements. The functions implemented are relatively small and are limited to the API.
The fourth type: SQLite for embedded development
This is an embedded database developed by D.Richard Hipp. It is realized by a small C library and becomes a powerful embedded relational database. basic functions. SQLite supports most standard SQL92 statements. SQLite stores the database in a single file format, which is one to two times faster than MySQL.
The above content introduces some databases that can be used in embedded training, each of which shows its own advantages in use, and can be used in different technologies to become our helper for storing data.
