MEMORY is designed to store data that must be accessed quickly, for example caches, or intermediate data that needs to be transformed before storing it to regular tables. In MariaDB and before MySQL 5.6, MEMORY was used for internal temporary tables, e.g. to materialize the intermediate results of a query.
All database objects – tables, queries, forms, etc. – are stored in tables of a single database (either file or server), making it easy to share data and design. Resulting database can be to certain extent manipulated using dedicated database tools. In Kexi, such data and definition of objects is known as project.

MySQL Workbench now uses ANTLR4 as backend parser and has a new auto-completion engine that works with object editors (triggers, views, stored procedures, and functions) in the visual SQL editor and in models. The new versions add support for new language features in MySQL 8.0, such as common-table expressions and roles.
Type of data structure selected for a certain task typically also takes into consideration the type of storage it resides in (e.g., speed of access, minimal size of storage chunk accessed, etc.). In some DBMSs database administrators have the flexibility to select among options of data structures to contain user data for performance reasons.
This is a comparison between notable database engines for the MySQL database management system (DBMS). A database engine (or "storage engine") is the underlying software component that a DBMS uses to create, read, update and delete (CRUD) data from a database.
SQLyog works on the Windows platform ranging from Windows Vista [10] to Windows 10. (Windows 9x/ME support was removed in version 5.0, Windows 2000 support stopped with version 8.6, and Windows XP support ended with version 12.5.) It has also been made to work under Linux and various Unixes (including macOS) using the Wine environment. [11]
