Key-value stores save data as associative arrays where a single value is associated together with a key used as a signifier for the value. No two keys necessarily need the same structure, so data is simply accumulated into a single, large table. Database administrators can quickly pull the data by identifying a specific key. A query language is not necessary when retrieving data, which provides convenience for users who are lacking query language knowledge. Key-value stores can also be used for web caches. Key-value stores are a type of NoSQL database and are the least structured of the schemaless data stores. Other types of NoSQL tools include include document database tools, graph database tools, object-orientated database tools and more. Those who need a solution at no cost can look at free database software.
