Data engineering for Decatur makers, shops and cafes
Decatur runs on its Square, a Wednesday market and a calendar of book and arts weekends. Sellers there keep short, scattered records. We gather them, fix them and chart them, one step at a time.
Decatur market afternoons as raw material
The farmers market meets on Wednesday afternoons from four to seven, rain or shine. Those three hours make a neat test: same time, same place, different goods and weather.
A seller who logs each week's sales builds a table by summer. Mining pulls it from a phone reader or notebook, and one row per sale is enough.
Decatur data engineering for festival weekends
The Decatur Book Festival fills the street fair on a Saturday, and the Arts Festival comes in May. A bookstore, a cafe or a maker can compare festival days against normal ones.
Cleaning matters here, because the rush on a festival day leaves messy entries. Typical slips are a product spelled two ways, a cash sale with no label. We standardize and merge, so each total can be trusted.
Questions a Decatur owner can ask
Which product do market regulars buy? Does the Square's foot traffic reach my side street? Analysis turns each into arithmetic, such as orders divided by visitors counted.
The final chart is deliberately plain, a bar or a line. The care is in the table beneath it. If a number looks off, you open the rows, find the sale and tell us, and we correct the table instead of arguing with the chart. A tidy table also lets a second question reuse the first one's work.
Students and visitors
Agnes Scott College and Columbia Theological Seminary add a campus calendar to the town's. Dated rows reveal whether term time changes your week, and a plain chart of sales by week lets you see move-in, finals and summer without trusting memory.
Public data helps too: we collect prices and review counts from pages that allow it, within each site's terms. A bar chart then puts your own prices beside those on the street, and you can see whether a gap is real or an artifact of how someone listed an item.
Questions from Decatur owners
I make goods by hand and sell at a few events. Is that enough data?
Yes. A handful of dated sales per event is a workable start. We show you what it supports and what extra detail would help.
Can you compare my prices with other sellers?
We can collect prices listed on public pages that allow it. We keep to each site's terms and put the figures beside yours.
Do I get to keep the table?
Yes. The table, the report and the charts are yours, and you can add rows after we finish.
