The most common database operations are Create, Read, Update, Delete (CRUD). “Database Management System” (or DBMS) refers to the piece of software for storing and managing that data. However, often the term “database” is also used loosely to refer to a DBMS, and you will find most DBMS only use the term database in their name and communication.<br /></p> <h3>What does “embedded” mean in the database world?</h3> <p>The term “embedded” can mean two different things when used in the context of databases:</p> <ol><li>“<strong>Database for </strong><a href="https://en.wikipedia.org/wiki/Embedded_system"><strong>embedded systems</strong></a>” is a database specifically designed to be used in embedded systems.
