JSON document databases store their data in files using a specific notation designed to eliminate the rigidity of relational database schemas. Also, developers can use data structure SDKs to serve up atomic attributes as key-value pairs. Or, indexing and querying can make JSON data appear as a table. A JSON database makes it possible to store data as JSON and provide it to applications in other forms.įor example, it can operate as an in-memory key-value store for applications that just need quick and easy access.
Processing Data ModelsĪ cluster can also have a mix of node types – data storage, processing, and serving data – using different access models. The system balances and replicates data to keep it available if a node becomes unusable. The underlying database partitions the data to maintain this balance using a pool of storage services in a shared-nothing architecture. Partitioning data across nodes allows distributed storage and processing where no single node is doing all the work. Developers also call this process “scaling out” the cluster. This cluster-based approach allows the database to add more nodes to create a larger data platform as needed. Thankfully, a cluster can easily expand storage. Instead, storage availability is the only limit to data volume.
A row count or table size does not constrain the number of documents stored in a JSON database. NoSQL JSON databases handle documents as individual data file objects without using structured tables. For example, where do you logically break your relationships in the underlying data? But it created challenges when scaling a graph structure across multiple database nodes. Graph data models were most helpful when memory and disk space were scarce. However, to do this requires a natively built data architecture with fancy design names like “index-free adjacency.” These structures associate each piece of data with a set of relationship ID numbers stored physically on a disk. Graph database structures can be fast, as they usually support in-memory processing to expedite relationship traversal speeds. In addition, other data structures, such as graph databases, may be too abstract for other use cases. However, key-value stores may be too simplistic for some use cases. Key-value database engines offer a means for writing data to persistent storage to reduce data loss. Of course, memory is volatile and power failures can erase data stored in memory. They often run primarily in memory, avoiding the time-consuming burden of reading data from spinning hard drives. There is also a focus on concurrency, high availability and real-time data persistence guarantees.įor example, some databases optimize key-value data storage for retrieval speed – aiming to run as fast as possible. NoSQL is a database category adapted to specific use cases that focus on storage structure, scaling design and query/indexing methods. JSON Databases Have More Storage Flexibility While we do, consider how you might be able to leverage its functionality in future applications. Let’s look at some of the advantages of a database that stores data in JSON format. JSON databases like Couchbase or MongoDB take advantage of the standard’s simple syntax, providing data structures readable by both humans and machines. Today the JSON data format is powering enterprise systems around the globe despite its humble roots in enabling JavaScript programming and simple web-based applications. Their popularity is due mainly to the simplicity and flexibility of the JSON database document structure.įirst introduced in 2006, JSON stands for “JavaScript Object Notation” and offers a less verbose data format than the popular XML (eXtensible Markup Language). This flexibility made JSON databases the preeminent storage structure for NoSQL systems that support multi-model or multi-modal processing.
In an era where physical storage limits are no longer a bottleneck, JSON databases deliver superior scale and performance. Instead, they flexibly adapt to a wide variety of data types, changing application requirements and data models. NoSQL database management differs from traditional relational databases that struggle to store data outside of columns and rows. What Is a JSON Database?Ī JSON database is arguably the most popular category in the NoSQL family of databases. They usually leave the room at this point, tired of indulging my enthusiasm for the Couchbase JSON database. Naturally, I had to explain that Jason is not the owner of my company! Instead, many modern databases use JSON as a data format. My family hears me talk about JSON databases rather frequently.
