MariaDB
MariaDB is a community-developed, commercially supported Fork (software development), fork of the MySQL relational database management system (RDBMS), intended to remain free and open-source software under the GNU General Public License. Development is led by some of the original developers of MySQL, who forked it due to concerns over its takeover, acquisition by Oracle Corporation in 2009, but in 2024 MariaDB plc was itself bought by the K1 private equity group, which appointed a new CEO. MariaDB is intended to maintain high compatibility with MySQL, with exact matching with MySQL Application programming interface, APIs and commands, allowing it in many cases to function as a drop-in replacement for MySQL. However, new features are diverging. It includes new storage engines like Aria (storage engine), Aria, InfiniDB, ColumnStore, and MyRocks. Its CTO is Michael Widenius, Michael "Monty" Widenius, one of the founders of MySQL AB and the founder of Monty Program AB. On 16 January ...

MySQL
MySQL () is an Open-source software, open-source relational database management system (RDBMS). Its name is a combination of "My", the name of co-founder Michael Widenius's daughter My, and "SQL", the acronym for Structured Query Language. A relational database organizes data into one or more data tables in which data may be related to each other; these relations help structure the data. SQL is a language that programmers use to create, modify and extract data from the relational database, as well as control user access to the database. In addition to relational databases and SQL, an RDBMS like MySQL works with an operating system to implement a relational database in a computer's storage system, manages users, allows for network access and facilitates testing database integrity and creation of backups. MySQL is free and open-source software under the terms of the GNU General Public License, and is also available under a variety of proprietary software, proprietary licenses. MySQ ...

Storage Engine
A database engine (or storage engine) is the underlying software component that a database management system (DBMS) uses to create, read, update and delete (CRUD) data from a database. Most database management systems include their own application programming interface (API) that allows the user to interact with their underlying engine without going through the user interface of the DBMS. The term "database engine" is frequently used interchangeably with "database server" or "database management system". A "database instance" refers to the processes and memory structures of the running database engine. Storage engines Many of the modern DBMS support multiple storage engines within the same database. For example, MySQL supports InnoDB as well as MyISAM. Some storage engines are transactional. Additional engine types include: * Embedded database engines * In-memory database engines Design considerations Information in a database is stored in the form of bits, laid out into ...

InfiniDB
InfiniDB (formerly Calpont Corporation) was a database management software company based in Frisco, Texas. The company developed InfiniDB, a scalable, software-only columnar database management system for analytic applications. InfiniDB is a scalable database built for big data analytics, business intelligence, data warehousing and other read-intensive applications. InfiniDB's column-store architecture enables very quick load and query times. Its massive parallel processing (MPP) technology scales with any type of storage hardware. In 2014, The company raised $7.5 million in a new round of funding led by McDonnell Ventures. Columnar databases By storing and managing data based on columns rather than rows, column-oriented architecture overcomes query limitations that exist in traditional row-based RDBMS. Only the necessary columns in a query are accessed, reducing I/O activities by skipping unneeded columns. InfiniDB is accessed through a MySQL interface. It then paralleli ...

Aria (storage Engine)
Aria is a storage engine for the MariaDB and MySQL relational database management systems. Its goal is to make a crash-safe alternative to MyISAM. It is not transactional. Aria has been in development since 2007 and was first announced by Michael "Monty" Widenius on his blog. Aria is used for internal temporary tables in MariaDB, a community-developed branch of the MySQL database led by Widenius. Aria is not shipped with MySQL or Percona Server. Aria was initially named "Maria", as a reference to Monty's youngest child. It was renamed Aria in 2010 to avoid confusion with the main database it is developed for, MariaDB. Chris Tooley, who won a contest to suggest the name, wrote, "Aria is Maria without the 'M'; also it is a pleasant musical term." Features Aria is very similar to MyISAM, but its purpose is to be a crash-safe alternative to MyISAM. Aria does not support foreign keys and, currently, transactions. Aria supports: * Fulltext indexes; * OpenGIS data types; * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relational Database Management System
A relational database (RDB) is a database based on the relational model of data, as proposed by E. F. Codd in 1970. A Relational Database Management System (RDBMS) is a type of database management system that stores data in a structured format using rows and columns. Many relational database systems are equipped with the option of using SQL (Structured Query Language) for querying and updating the database. History The concept of relational database was defined by E. F. Codd at IBM in 1970. Codd introduced the term ''relational'' in his research paper "A Relational Model of Data for Large Shared Data Banks". In this paper and later papers, he defined what he meant by ''relation''. One well-known definition of what constitutes a relational database system is composed of Codd's 12 rules. However, no commercial implementations of the relational model conform to all of Codd's rules, so the term has gradually come to describe a broader class of database systems, which at a ...

Fork (software Development)
In software development, a fork is a codebase that is created by duplicating an existing codebase and, generally, is subsequently modified independently of the original. Software built from a fork initially has identical behavior as software built from the original code, but as the source code is increasingly modified, the resulting software tends to have increasingly different behavior compared to the original. A fork is a form of branching, but generally involves storing the forked files separately from the original; not in the repository. Reasons for forking a codebase include user preference, stagnated or discontinued development of the original software or a schism in the developer community. Forking proprietary software (such as Unix) is prohibited by copyright law without explicit permission, but free and open-source software, by definition, may be forked without permission. Etymology The word ''fork'' has been used to mean "to divide in branches, go separate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Free And Open-source Software
Free and open-source software (FOSS) is software available under a license that grants users the right to use, modify, and distribute the software modified or not to everyone free of charge. FOSS is an inclusive umbrella term encompassing free software and open-source software. The rights guaranteed by FOSS originate from the "Four Essential Freedoms" of '' The Free Software Definition'' and the criteria of '' The Open Source Definition''. All FOSS can have publicly available source code, but not all source-available software is FOSS. FOSS is the opposite of proprietary software, which is licensed restrictively or has undisclosed source code. The historical precursor to FOSS was the hobbyist and academic public domain software ecosystem of the 1960s to 1980s. Free and open-source operating systems such as Linux distributions and descendants of BSD are widely used, powering millions of servers, desktops, smartphones, and other devices.
