MySQL derives part of its name from the SQL language, which is used for managing and querying data in databases. MySQL offers full ACID transactions and can handle a high volume of concurrent connections. MySQL Explained MySQL is an open source RDBMS that uses SQL to create and manage database...
NoSQL databases, on the other hand, embrace situations where the ACID model is overkill or would, in fact, hinder the operation of the database. Instead, NoSQL relies upon a softer model known, appropriately, as the BASE model. This model accommodates the flexibility offered by NoSQL and ...
Durability in databases is the property that ensures transactions are saved permanently and do not accidentally disappear or get erased, even during a database crash.
