GoalGoal
Efficiently generate data summaries quick and easy consistent repeatable accurate using your live monitoring data
![Page 3: A monitoring data summary tool](https://reader035.fdocuments.in/reader035/viewer/2022062323/56815be8550346895dc9dd8b/html5/thumbnails/3.jpg)
ChallengesChallenges
There are many summary challenges with a large growing dataset.– Timely data summaries
• When can we get it done?• Is it easy to do?
– Consistent results year to year• Are the data summaries repeatable?• Can your replacement do them after you leave?
– Can adjustments be made easily• Can summary calculations be easily checked?• Can edits, additions or subtractions be made?

ApproachesApproaches
Export data to a package for summary calculation and analysis Excel, SAS, SYSTAT
Do summary calculations in your database Use Queries and other database tools
Some combination of the two

Our StrategyOur Strategy
Use tools in Access to calculate summary metrics in a sister summary database– Use a separate database to capture and
define the database snapshot that the summary represents
– Compartmentalize each metric calculation• Ensure calculations are done properly• Facilitate updates, additions, and edits
– Document calculations and keep that and the means of calculation with the data

Our ImplementationOur Implementation
Define a standard input data format Collaborate to design and document a
set of queries that calculate a metric Automate exporting metrics into a
results table Analyze, display and report with
metrics from the results table
