When Is a Graph Database the Best Option?

A graph database is the storage of sorts for all the isolated information surrounding our rich, connected domain world. A database that natively embraces relationships where you can store and process any query connections efficiently is the best option. It is very identical to a mathematical graph; however, it does not allow the user to connect data. You can use Create, Read, Update and Delete (CRUD) operations to work your way on a graph data model.

A user can only take advantage of specific functions from within the database that helps with data analysis in a graph database software. However, unlike other databases, relationships take priority in graph databases. It means that the application does not have to infer data connections using foreign keys or out-of-band processing.

To finalize the reason to use a graph database, you need to understand that you might also want to generate insight from the existing data for your venture. Relationships between data points matter more than the individual points. You should opt for graph database building if your queries do not execute bulk data scans or start from a known data point.

It is better not to use a graph database software, such as Dgraph, to optimize for writing and storing data, not just for reading or querying it. It is also a smart move to not use a graph database if your core data objects or model stays consistent and the data structure is tabular and fixed.

If you are only looking for a lookup operation, a graph database is not the solution. For example, someone might use a database as a cache to store session data for an application. You would store the session ID in the cache but then write the session details to the database. For retrieving, you would only have to send the session id as the key to return the value.

Business and technical needs, where the user wants to understand the data relationships, are the key market for a graph database. It helps to understand what the user wants, assisting the users in devising well-rounded customer profiles to find outliers that could be fraud signs.
