Graph databases refers to a category of NoSQL databases that represent data whose relations are well represented as a set of nodes. These nodes have an undetermined number of connections and are evaluated through computer algorithms. Good graph database use cases include: Social relationships (nodes are people) Public transport links (nodes can be bus or […]
Next and Prior: Pointing in Data Models
Click to learn more about author Thomas Frisendal. Pointers have been in and out of data models. From the advent of the rotating disk drive in the 60s and until around 1990, pointers were all over the place (together with “hierarchies”, which were early versions of aggregates of co-located data).
