CouchDB: What is it and what is it used for?
CouchDB is a NoSQL solution or a document-oriented database in which all document fields are stored as key value tables. These document fields are simple key values, value pairs, lists or tables. The software breaks with traditional databases because it offers numerous advantages, such as:
- multiple libraries
- the document format JSON
- Fast retrieval and indexing
- REST-like deletion, retrieval and updating of documents as well as insertion of texts
- Simple database replication across multiple servers
The software helps you access your data wherever it is needed. This is achieved by deploying the clients to different products and projects within the computing environment using a couch replication protocol.
Using the globally distributed server clusters, you can access mobile phones via web browsers. You can securely store client data either with leading cloud providers or on the clients' own servers. The client's native and web-enabled applications are supported by binary data and JSON.
There is a replication protocol that ensures seamless data flow between the server clusters and the web browsers and mobile phones. In turn, it enables the offline first user experience while maintaining high reliability and performance.
Developers can further enhance comprehensive, efficient and simple data retrieval with MapReduce (optional) and the developer-friendly query language. It is free to use, open-source, and the client's current data can be easily integrated into the software.
The infrastructure is built in such a way that there will be no lock-in by the providers regarding the clients. It also gives the clients control over the software as well as flexibility as it can be adapted to the different needs of the organisation. The offline-first mindset ensures efficient data synchronisation and guarantees that clients can build scalable, reliable and durable infrastructures.
There is Multi-Version Concurrency Control (MVCC), which ensures that clients can easily manage all databases simultaneously. Therefore, the software will run independently of the load of the Database unrestricted and executed at full speed.
Support from the open source community ensures that a reliable and strong foundation is always in place. Development is ongoing to provide clients with continuous support and unparalleled flexibility. The software is constantly optimised to be able to integrate new technologies.
The architecture guarantees that clients can partition their databases into multiple nodes. Using this software ensures that the client can either replicate or partition the database horizontally to balance the read and write workload. So this software is very helpful when installed.
