Delete All Documents that Match a Condition. A great option for testing and performing local development with MongoDB is using Docker and Docker Compose. MongoDB is an open source NoSQL Document database which horizontally scales utilizing clustered servers in replica-sets. If the collation is unspecified but the collection has a default collation (see db.createCollection()), the operation uses the collation specified for the collection. For descriptions of the fields, see Collation Document. Although most of the NoSQL databases offer a solution to achieve ACID compliance if it is needed. When specifying collation, the locale field is mandatory all other collation fields are optional. Learn how to delete documents from a MongoDB collection using Compass, a graphical user interface for MongoDB. Most SQL Databases are ACID compliant by default where NoSQL databases can sacrifice ACID compliance for performance and scalability. Databases are evaluated on their ACID Compliance (Atomicity, Consistency, Isolation, Durability) which is a standard set of properties that guarantee database transactions are processed reliably. On the other hand, NoSQL databases are built to horizontally scale and are typically deployed with multiple servers in a replica-set, so handling more load is as simple as adding a new server. SQL databases are built to vertically scale which means they are ran on a single server and to handle more load you need to increase the CPU and Memory on that server. NoSQL databases come in the following types Key-Value, Wide-Column, Graph, and Document but we will mainly be taking a look at document databases specifically MongoDB, which store data in documents that are grouped together in collections. SQL databases are relational and structured and usually consist of tables of rows and columns. There are two main types of databases that can be used in applications and these include NoSQL databases and SQL databases.
