Deleting a database because it’s old (neglect of historical data)

Sometimes companies want to save money and delete historical data because they consider it unnecessary. Or system administrators suggest cleaning up data older than two years to optimize server costs.

Historical data is very important. It stores information about revenue, average check, website traffic, conversion and customer churn of the company over the past years. Accordingly, the richer and more voluminous the historical material, the more accurate the forecast can be.

For example, based on historical data, you can make a revenue forecast for the next year. In its simplest form, this can be done directly in an Excel file using the forecast.ets function. The program will compare changes in revenue from year to year, calculate the seasonality of changes, and make a revenue plan for the next year.

Let me give you an example of a furniture company case. It had a huge 1C database. They were packed incorrectly, and someone decided that it was better to delete everything and not pay for storage. But this historical data, although not ideal, could be used to assess important trends.
