>a1 STATISTICS
>a2 Introduction
This is a result of an analysis of the statistic feature that
should be included in the DA-system.
The basic idea is that the user through a
>ul
dialog
with the system retrieves the statistic information that he wants.
The user first has to select between three modes:
- the defining mode
- the removing mode
- the ordering mode
In the defining mode he is able to define his own special statistics
by using the system defined
>ul
statistic primitives
i.e. a set of calculated figures.
To define a statistic means to define a statistic program that
>ul
produces
statistics. The user can
>ul
name
(or store) this program and then use it over and over again.
In the removing mode previously defined statistics can be removed
or cleared i.e. the programs making special statistics will no longer
be available.
In the ordering mode the user can order either one of the system
defined statistics or one of his own previously defined statistics.
He first has to set up a
>ul
statistic frame
i.e. a frame within which the statistic should be produced. The frame
includes the
>ul
period of time
of the statistic, the
>ul
set of information
used to calculate the figures.
If a cheaper solution is wanted, it could only include the ordering
mode and only allow system defined statistics.
>a2 Defining mode
When this feature is selected, the user is able to design his own
statistics by using the system defined
>ul
statistic primitives
i.e. the set of figures calculated by the system. The set of
statistic primitives are described in appendix 1.
The actual design is done through the following
>ul
dialog
with the system.
First the user will be presented for an empty layout of an output page.
(See DEFINING MODE FORMULA 1 and DEFINING MODE FORMULA 2).
He then has to fill in the statistic primitives
and new figures calculated from the primitives which he wants.
One per line. The statistic may consist of several pages.
Secondly he has to define the new figures which he wants the system to
calculate
which figures are wanted in per cent of what and so on. This is done
through a
>ul
special language
and through DEFINING MODE FORMULA 3.
>np
>fg DEFINING MODE FORMULA 1
>np
>fg DEFINING MODE FORMULA 2
>np
>fg DEFINING MODE FORMULA 3
>np
>a3 Storing the statistics
When the user has defined the total layout of his statistic
and the rules for calculating non primitive figures as
mentioned above this statistic program will be
>ul
stored
by using the
>ul
name
it was given by the user.
In this way the user is able to supplement the system defined
statistics with his own special statistics. He only has to
define them once. Then he can use them over and over again.
>a2 Removing mode
All user defined statistics may be removed or cleared which means that
they no longer will be present. The removing is done through the
REMOVING MODE FORMULA.

>a3 Introduction
Whenever you want to make statistics on some subject you have to know
>ul
the history of the subject.
The part of the history of the subject that is
>ul
relevant
when making some statistic, we will call
>ul
the statistic frame.
The statistic frame is specified by two subjects. These are
>ul
the period of time of the history
that should be covered by the statistic and the
>ul
set of information
(part of the information of the history) on which the figures of the
statistics are calculated.
>a3 The history of the DA-system
The DA-system includes a LOG-PROCESS, which produces a
>ul
total history of the system
on a so-called LOGFILE.
The history consists of records of information about each retrieval
from each operator position and from each operator. These records
of information are sorted in time.
>a3 Specifying the statistic frame
In order to specify the statistic frame the user has to state the
period of time and the set of information.
This is done through the ORDERING MODE FORMULA 1.
>np
>fg ORDERING MODE FORMULA 1
>np
>a4 The period of time
The period of time is specified as a date interval and a time interval.
>ex
81.03.03 - 81.03.08, 9.00 - 12.00
designates that the period of time of the history covered by the
statistics is March 3rd - March 8th 1981 from 9.00 to 12.00.
If the date interval is omitted the actual date is assumed.
If the time interval is omitted the interval 0.00 - 24.00 is assumed.
>a4 The set of information
The figures of the statistics will be calculated on information
extracted from the part of the history specified by the period of time.
Sometimes all the information is not relevant.
If a statistic only concerning the work done by a
special group is wanted all information about other groups are
irrelevant. Selecting the set of information is done by selecting
the
>ul
set of operators/operator positions
which is wanted.
This will be described below.
When selecting the set of operators/operator positions the following
possibilities exist:
>ul
1. All (default)
- All operators/positions are included i.e. all records of information
logged in the specified period of time are used in calculating the figures
of the statistics. The figures calculated will then be system totals.
>ul
2. Group(s) of operators
- Only the specified group(s) of operators are included i.e. only the
records of information from operators in the specified access-group(s)
logged in the specified period of time will be used in cal_culating
the figures.
- If only one group is specified the figures calculated will be
group-totals.
- If more than one group is specified there will be calculated a set of
figures for each group, which is group-totals and a set of figures
that is totals of the total number of operators in the specified groups.
>ul
3. Group(s)/operator
- Only the specified group(s) of operators are included i.e. only the
records of information from operator's in the specified access-group(s)
logged in the specified period of time will be used in calculating
the figures.
- If only one group is specified there will be calculated a set
of figures per operator of the group, which is operator totals and a
set of figures, which is group-totals.
- If more than one group is specified there will also be produced
a set of figures designating all the operators involved.
>ul
4. Operator(s)
- Only the specified operator(s) are included. I.e. only the
records of information from the specified operator(s) logged in the
specified period of time will be used in calculating the figures.
- If only one operator is specified, there will be calculated a set
of figures, which is operator totals.
- If more than one operator is specified there will be calculated
a set of figures per operator which is operator totals and a set
of figures which is totals for all the operators specified.
>ul
5. Group(s) of positions
- As 2. group(s) of operators using the records of information logged
from position groups instead of records from operator groups.
>ul
6. Group(s)/position
- As 3. group(s)/operator using the records of information logged
from position groups instead of records from operator groups.
>ul
7. Position(s)
- As 4. operator(s) using records of information from positions
instead of records from operators.
>ex
The user has selected group(s)/operator and specified two different
groups with each 4 operators. He has
now decided that he wants the statistic (which he is going to choose later)
presented in the
following way:
4 operator statistics from group 1
1 group statistic from group 1
4 operator statistics from group 2
1 group statistic from group 2
1 total statistic (group 1 + group 2)
In this way the statistic frame indicates that each chosen type of
statistic will be presented in 11 different surroundings.
Note that the figures of the total statistic not necessarily are the
sum of group 1 and group 2 figures, since the groups may have
common members.
>a3 Selecting the type of statistics
When the user has set up a statistic frame, he then has set up the
surroundings which he wants and he is then able to select the type
of statistic which he wants to produce.
The statistics are selected through the ORDERING MODE FORMULA 2.
These are divided into 5 types:
1. General statistics
2. Special statistics
3. Distributions
4. Summary reports
5. User defined statistics
Type 1 and 2 concern information about the inquiries.
Type 4 concerns information about operator performance.
Type 3 concerns information about interesting system
figures (i.e. average response time, number of input
charcter etc.).
Type 5 is the statistics defined in the defining mode.
Types 1 - 4 are described in greater details below.
The suggested figures in the statistics are not complete, it
is only a proposal.
