installation for each type of connection differ, and are explained separately below.

Note: The amount of storage space necessary for the data files depends on the archive
interval. Each archive record in the database is 88 bytes. Every day in the database
has an additional two records totalling 176 bytes that store daily summary informa-
tion. A database containing data stored at a 30-minute archive interval requires
approximately 4400 bytes of disk space per day or 132KB of disk space per month.
The disk space requirements change in a linear fashion depending on the archive
interval. For example, data stored at a one-minute interval requires approximately 3.8
MB a month while data stored at a two-hour interval requires approximately 32 KB a
month.
