mySqlService.php

mySqlService.php is an implementation of a webservice that implements generating hyperslices for the MySQL database. It is used in the online examples on the Ravelation website.

The dataset is assumed to have a simple structure. The database needs to have a separate row for each data element. There are two reserved column names, id$, which is the primary key (if any), and value$ which is the column containing the values. There is a column for each dimension of the hypercube, filled with the slice labels for each data item. The full hypercube of data need not be present - any missing data is filled with NaN on output.
