Sir Tim Berners-Lee:
Inventing the World Wide Web involved my growing realization that there was a power in arranging ideas in an unconstrained, web-like way. And that awareness came to me through precisely that kind of process.
Let’s think how the different data models require us to arrange data:
- hierarchical model: free form, single-type of relationship (parent-child)
- relational model: strict form, (limited) multiple-types of relationships
- document model: free form, dual relationship types: logical and hierarchical
- star schema: strict form, (limited) multiple-types of relationships
Now think about graph databases: free form (nodes can have any number of properties), unlimited number of uni/bi-directional relationships. So question is, why aren’t network/graph databases used more these days?
