### [FaircomDB](https://www.g2.com/products/faircomdb/reviews)

FairCom DB is an advanced database engine that gives you ultimate control to achieve unprecedented performance with the lowest total cost of ownership (TCO). FairCom’s NAV API gives your application an unprecedented level of control over every database action. NAV allows your favorite programming language to precisely control the database. It can find any record (or a subset of records), move to next and previous records in index or data order, join to specific records in other tables, choose which records to lock, which records to include in a transaction, and which records to retrieve, insert, update, and delete. NAV allows you to save the position of records and immediately jump back to those positions to retrieve records without index lookup. You can run SQL simultaneously with any NAV operation. This gives your application the best of both worlds. SQL solves easy problems with little code. NAV solves hard problems with little code by leveraging the full capabilities of mainstream programming languages, such as Java, C#, C++, Python, and Javascript. NAV extends these languages to control the database with a small amount of simple code. NAV provides unprecedented speed because your application uses the ideal algorithm to make the database do exactly what needs to be done and no more.

Key value databases 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 databases can also be used for web caches. Key value databases are a type of NoSQL database and are the least structured of the schemaless data stores. Other types of NoSQL tools include [document database](https://www.g2.com/categories/document-databases) tools, [graph database](https://www.g2.com/categories/graph-databases) tools, [object-orientated database](https://www.g2.com/categories/object-oriented-databases) tools and more. Those who need a solution at no cost can look at [free database software](https://learn.g2.com/free-database-software).

To qualify for inclusion in the Key-Value Store category, a product must:

- Provide data storage
- Store data as a singular value associated with a key
- Allow users to retrieve the data
