Recent questions tagged database
The term "database" refers to both structured collections of data as well as the management systems for those collections. There are various types of databases: relational, hierarchical, object-oriented, NoSQL, etc. The most commonly known type are relational databases, usually in the form of SQL databases. Examples for those are MySQL, PostgreSQL, Oracle, or Microsoft SQL-Server. Basic example for hierarchical databases are filesystems or XML documents. NoSQL databases are a more recent development, positioned as alternatives to classic SQL databases in situations where performance or availability is of higher importance than guaranteed data consistency.
