Key Value Database Example. A Key-Value database also popularly known as Key-Value Store is a data storage model designed for storage retrieval and managing associative arrays. An example of the tuples data format in Relational Database. A key-value store is a simple database that when presented with a simple string the key returns an arbitrary large BLOB binary large object or sometimes. Because database is in itself a very simple also very simply is its query language.

The values can be of scalar data types such as integers or complex structures such as JSON lists BLOB and so on. A Key-Value database also popularly known as Key-Value Store is a data storage model designed for storage retrieval and managing associative arrays. Key value stores help the developer to store schema-less data. Each key has one and only one value.

PickleDB got its name from Pythons pickle module which it used to use. All keys must use VARCHAR for the value. Basic large object of data the value. For example a key-value pair may contain a key like Website associated with a value like Guru99. 39 rows A keyvalue database or keyvalue store is a data storage paradigm designed for. For example a relational database management systems RDBMS may also support keyvalue or graph storage.

Key value stores help the developer to store schema-less data. Each key has one and only one value. Unlike the key-values format it relies on the predefined schema to organize records into rows and its values in fixed-length columns. You can store a value such as an integer string a JSON structure or an array along with a key used to reference that value. Generally however key-value stores are.

A key-value database stores data as a collection of key-value pairs in which a key serves as a unique identifier. This kind of NoSQL database is used as a collection dictionaries associative arrays etc. In key-value stores keys or ids and values are stored in pairs. The basic data structure is a dictionary or map. A telephone directory is a good example where the key is the person or business name and the value is the phone number.
