How CentreVu CMS Stores Data
17-4
Each row in a table contains data that is related by the value(s) of one or
more of the columns. For example, each row in the Current Interval
Agent table contains data related by agent login ID. If you look at the row
for login ID 1006 (displayed in bold), you see that the agent is logged into
Split 1 on extension 5671 and is currently in AUX work mode. In addition,
up to this point in the current interval, the agent has had:
●
20 ACD calls
(ACDCALLS)
●
245 seconds of ACD talk time
(ACDTIME)
.
A column that causes the values in a row to be related is called an index.
An index stores data sequentially and adds structure for the storage of
data in the other columns. For each value in an index column, the
remaining values in the corresponding row are related to that value.
Thus, the first figure, the LOGID database item is an index.
In the second figure, each row in the Intrahour Interval Split table
contains data related by date, interval, and split. If you look at the row for
Split 1 for the 10 o’clock interval on July 1, 1993 (displayed in bold), you
see that Split 1 had:
●
509 ACD calls
(ACDCALLS
)
●
43 abandoned calls
(ABANDONS
)
●
35,401 cumulative seconds of ACD talk time for all ACD
calls
(ACDTIME
)
●
851 cumulative seconds of wait time for all calls that abandoned
before being answered
(ABNTIME
).
