What are the main industries where MYSQL is used
Mysql is mainly popular and is open source software.
This collection of data has the following characteristics: it is as non-duplicative as possible, serves multiple applications in a particular organization in an optimal way, and its data structure is independent of the applications that use it.
Additions, deletions, changes, and retrieval of data are managed and controlled by unified software. Historically, databases are an advanced stage of data management, having evolved from document management systems.
The name of MySQL’s dolphin logo is “sakila”, which was chosen by the founders of MySQLAB from a large list of names suggested by users in a “dolphin naming” contest. It was chosen by the founders of MySQLAB from a large list of names suggested by users in a “Dolphin Name” contest. The winning name was provided by Ambrose Twebaze, an open source software developer from Swaziland, Africa.
According to Ambrose, Sakila comes from a Swazi dialect called SiSwati and is the name of a town in Arusha, Tanzania, near Ambrose’s hometown of Uganda.
MySQL, though not necessarily powerful, is an open-source, widely distributed database that many people have learned about. It also has a storied history.
What can mysql database do?
Mysql is the most popular relational database management system and one of the best RDBMS (RelationalDatabaseManagementSystem) applications for WEB applications.
MySQL is a relational database management system that was developed by MySQLAB in Sweden and is now owned by Oracle.MySQL is an associative database management system, where the associative database keeps the data in different tables instead of keeping all the data in one big repository, which increases the speed and improves the flexibility.
Mysql is open source, so you don’t need to pay extra.
Mysql supports large databases. It can handle large databases with tens of millions of records.
MySQL uses a standard form of SQL data language.
Mysql can be allowed on multiple systems and supports multiple languages. These programming languages include C, C++, Python, Java, Perl, PHP, Eiffel, Ruby, and Tcl.
Mysql has excellent support for PHP, which is currently the most popular web development language.
MySQL supports large databases, a data warehouse of 50 million records, table files of up to 4GB on 32-bit systems, and up to 8TB on 64-bit systems.
Mysql is customizable with the GPL agreement, and you can modify the source code to develop your own Mysql system.
Mysql database concept, technical connotation, scope of application (briefly describe the meaning of database)
The role of the database is to manage a variety of data in an orderly manner, and to provide a unified interface and services to other applications.
The database is a collection of data stored in a certain way, which can be shared with multiple users, has the smallest possible redundancy, and is independent of each other and the application programs, and can be regarded as an electronic filing cabinet – a place where electronic files are stored, and where the user can add, query, update, delete, etc., the data in the files. The user can add, query, update, delete and other operations on the data in the file.
The database is a storehouse of data. It has a large storage space and can store millions, tens of millions, hundreds of millions of data. But the database does not store data randomly, there are certain rules, otherwise the efficiency of the query will be very low.
Today’s world is an Internet world filled with data, filled with a lot of data. That is, this Internet world is the world of data. There are many sources of data, such as travel records, consumption records, web pages viewed, messages sent, and so on. Apart from text type data, images, music, sound are all data.
In the history of the development of databases, databases have gone through various stages of development such as hierarchical databases, mesh databases, and relational databases, and the database technology has been developing rapidly in various aspects. In particular, relational databases have become the most important member of the current database products.
Since the 80’s, almost all new database products from database vendors support relational databases, and even some non-relational database products almost always have interfaces that support relational databases. This is mainly because traditional relational databases can better solve the problem of managing and storing relational data.
With the development of cloud computing and the arrival of the big data era, relational databases are increasingly unable to meet the needs of this is mainly due to the increasing number of semi-relational and non-relational data need to use the database for storage and management, at the same time, the emergence of new technologies such as distributed technology also put forward new requirements for the database technology, so more and more non-relational databases began to appear.
These databases and traditional relational databases in the design and data structure is very different, they emphasize the database data of high concurrency read and write and storage of large data, this type of database is generally known as NoSQL (NotonlySQL) database. And traditional relational databases still maintain a strong vitality in some traditional areas.
What are the common types of databases used? Try to describe the characteristics and scope of use of each type of database
Relational databases, non-relational databases.
1. Relational database
Features: centralized control of data; reduce data redundancy etc.
Scope of application: more appropriate for the processing of structured data, such as student grades, addresses, etc., such data generally need to use structured queries.
2, non-relational database
Features: easy to expand; large data volume, high performance; flexible data model.
Used: according to the model is relatively simple; the need for more flexible IT systems; higher requirements for database performance.
Categorization of non-relational databases:
