Database and sql:
Create a relational database with one table called Triplets.
Triplet: (object, attribute, value)
As well as using 4 optional attributes, you need to use three other attributes namely is-a, part-of, and instance-of. The first predicate, is-a, shows class and subclass relationship. Also, as the name of the second predicate represents, it shows that an element is part of another element. The third predicate shows membership relationship.
- With using URIs with the maximum length of 8, fill the tables with your own triplets. Your table needs to have an appropriate number of meaningful rows, say 40 related rows of any anthology you like.
- Write 10 different quires searching your dataset for meaningful questions. Each of your first five queries needs to use the triplet table four times and each of other five quires should use it at least six times.
