Faultless collection can die on delivery. Clean data, a format nobody on the team knows how to open, project abandoned three weeks later.
Format is chosen according to who will use it.
The CSV or spreadsheet file
Unbeatable for a one-off analysis. It opens anywhere, travels by email, sorts and filters without any particular skill.
Its limit arrives quickly: it freezes a moment. As soon as it needs refreshing weekly, someone has to do it by hand. And that someone eventually forgets.
The database
It becomes necessary when history matters. Following a price over six months, comparing two periods, spotting a trend: none of that works with a file overwritten at every reading.
Every measurement stays dated and queryable. That is what lets you answer “and last year, same date?”
The API
The right call when the data has to feed something else. A CRM to enrich, a site to populate, an internal tool to supply. Your application asks, receives, and no file travels or piles up anywhere.
It takes the most engineering up front and saves the most handling afterwards.
The dashboard
For people who do not want data but answers. A sales director will never open a two-hundred-thousand-row file. They will look at five figures, with room to dig if needed.
Often two at once
Projects that last tend to combine: a database that keeps the history and feeds an API, plus a weekly export for the team that prefers its spreadsheet.
Ask the question this way round: who will open this, and to do what? The technical answer follows. Let's talk.
