How big is a billion triples?

Question

Is it possible to relate the size of triple storage with gross equivalence in terms of RDBMS? Or it depends too much on the type of data stored (in my case the CMS text content)

I'm trying to figure out how a 800 MB database compares to a 1.7 billion triple triple store. I am fully prepared to say that this is a stupid question.

Answer 1

It is difficult to answer the question, but it is not stupid.

In general, you can convert from a table the size into a triple score with something like:

triples = columns - 1 * rows

This is a bit redundant generalization, but it should give you some idea, for example. if you have a table like:

prikey val1   val2
a      1      2
b      3      4
c      5      6

6 , NTriples, :

<a> <val1> 1 .
<a> <val2> 2 .
<b> <val1> 3 .
<b> <val2> 4 .
<c> <val1> 5 .
<c> <val2> 6 .
