•Merlin presents the
database as a "chemical spreadsheet" called a pool.. The
data are seen in rows and columns. The results of searches are stored in hitlists.
–A pool is a THOR
database that is loaded into the computer's memory.
–A row is Merlin's representation of a THOR datatree. That is,
all data in one row are
from a single TDT in one database.
–A hitlist is an
ordered subset of the rows in the pool. Sorts and searches modify hitlists: A search adds or deletes rows
from a hitlist, and a sort
changes the order of the rows in a hitlist.
–A hit is a row
that is currently in a hitlist.
–A column is a "vertical slice" through the pools, and
contains data of one
particular datatype. For example, a column might be for the datatype "Name," the column would contain a
name from each row of the pool.
