While the network is "down" and Symphony Pro cannot communicate with the front end:

·No new item prices can be obtained, but the Symphony POS front end stations/cash registers work
from their local item database. Local "price override" can be used to modify prices if required.
·Floating cashier balance reports cannot be generated until the system returns to normal operation.
·No customer account balances will be available until the system returns to normal, but the Symphony
POS front end station will prompt the cashier with a "server not available - continue anyway?" error
message. At this point it is up to the store manager to allow or not allow account charges during a
network down.
·No financial reports for the cash register can be taken from the Symphony Pro back end station.

Data Maintenance

Controlling Database Size

Except for hardware configurations, Symphony Pro keeps all data in database tables. The original size
and growth in size of the database tables depends on the number of items, the amount of transactions
per day, and other factors. Daily transactions which include PLU sales information are probably the
biggest factor, taking up large amounts of space. Large amounts of data can also slow down the
processing times for database operations. Some database types are more robust, but eventually, even
Paradox databases cannot handle the amount of data. These tasks are automated with the Task
Manager, and are included in a default Symphony Pro installation.

Instead of keeping all daily data, Symphony Pro provides automated utilities that consolidate sales
information into weekly, monthly and yearly totals. The consolidation process is also automated by the
Task Manager, and greatly reduces the amount of space the information occupies in the database
report tables.

Daily Maintenance Process

As the front end Symphony POS terminals perform transactions, they place the resulting information in
both their Electronic Journals and "Outbox". The controlling Symphony Pro station picks up this sales
data and posts it to the report tables in the database. This creates many daily records that occupy large
amounts of space in the database. The daily maintenance process consolidates the information from
all Symphony POS lanes, eliminating many of the records. For example: during a daily period, a front
end lane has sold 300 PLU 1. Each time the PLU sold, a record was created. The Daily Maintenance
process will combine all 300 records into a single record, saving database space. It also combines all
front end lanes. Following the PLU 1 example above, if all lanes sold PLU 1, there will be a single
record for all PLU 1 sales that day.

Monthly Maintenance Process

As time passes in an operational situation, data continues to grow. Each month, Symphony Pro runs
another maintenance operation to control database size. The Monthly maintenance process further
reduces the database size by eliminating daily data from the past. In most situations, daily data is not
required after about 90 days. With the exception of daily financial data, the monthly process eliminates
daily data, keeping weekly, monthly and yearly totals. Every month when the process runs, it leaves the
most recent 90 days of daily data untouched, but removes daily data from before the 90 day period.

NOTE: By default, Symphony Pro keeps the daily financial data for 365 days. The cleanup
period can be defined in the configuration settings. We recommend you consult your
