Hi,
I did a Google search on timeseries and database and found some research called Sorted Relational Query Language. Also SQL-TS. I have a few questions beyond what I found.
Does anyone know where there is reseach on the method of storing columns instead of relations, called inversion I believe? What I am after is an understanding of the techniques available to manipulate (i.e. query against) result sets as big as a 500,000*5,000 matrix of a 2 element aray containing a unique identifier and a numeric value that would perform very fast.
Are there any are there any implementations of SRQL or SQL-TS?
Thanks
