An advantage of CouchDB is the quality of synchronization of several databases, as efficient synchronization is important for distributing data in a CouchDB cluster. In this way, the resulting data redundancies relieve the entire system. Consequently, database requests can be responded to by different CouchDB authorities. Geographically distributed, giant database networks are easily achievable.
When synchronizing the database for different users at different locations, Apache CouchDB relies on an incremental strategy which has the crucial benefit of preventing poor or discontinued network connections from negatively affecting the synchronization process. If there are connection problems, the database solution continues where it left off before the connection was disrupted. With respect to these instances, the developers have emphasized that the system doesn’t ignore these types of eventualities and assumed that such errors can happen in everyday life.
Furthermore, CouchDB uses the beginner-friendly JSON format (short for Javascript Object Notation) for the transfer and storage of its data sets. This format owes its existence to its schema-free structure, which – unlike with relational models – allows for unstructured information to be stored.
Users can also count on the simple operation of CouchDB, as it relies on current and well-known web technologies such as REST, JSON, and JavaScript. There is nothing to prevent diverse usage that ranges from large server clusters to mobile end devices.
