DRE vs the usual ways to automate reports
Most recurring reports are produced by a script, a BI subscription, a report server or a spreadsheet someone updates by hand. Each has its place. Here is how they compare with reports as code, and when you should keep what you have.
DRE vs Python scripts and cron
- What it does well
- Total flexibility. Anything you can code, you can produce, and a script is quick to write for one report.
- Where it gets hard
- Every report becomes its own small program. Formatting Excel, retrying an SFTP upload, masking secrets and logging are rewritten in each script, usually by whoever wrote the first one. Reviewing a change means reading code, not a report definition.
- How DRE differs
- The report is declared in SQL and YAML; formats, destinations, retries, secrets and logs are DRE’s job, the same way for every report. A new report is a new folder, not a new program.
- Keep it when
- The output needs logic no report tool expresses, such as calling an API per row or building a PDF layout.
DRE vs BI tool email subscriptions
Power BI, Tableau, Looker and similar
- What it does well
- If the dashboard already exists, a subscription is a few clicks, and readers get a picture of what they already know.
- Where it gets hard
- Subscriptions send what the dashboard shows: usually a PDF, an image or a basic export. An exact file layout, a fixed-width file for a bank, or a delivery to SFTP or a bucket is out of reach, and the definition lives in the BI tool rather than in git.
- How DRE differs
- DRE produces the exact file (named tabs, number formats, formulas, totals, fixed-width columns) and delivers it anywhere, from definitions reviewed in git. For people who only want the numbers, it posts a headline message to Slack or email instead (Microsoft Teams and Google Chat are in preview).
- Keep it when
- People want a snapshot of a dashboard they already use, and nobody needs the data as a file.
DRE vs SSRS and Crystal Reports
SQL Server Reporting Services, Crystal Reports
- What it does well
- Pixel-precise printed layouts, built-in subscriptions, and a long track record in Microsoft and enterprise shops.
- Where it gets hard
- Reports are designed in a GUI and stored as XML, so diffs and reviews are hard. They are tied to a report server, and modern cloud warehouses and object storage are not their home ground.
- How DRE differs
- DRE is a single command-line tool with no server: plain files in git, cloud warehouses and object storage first, run by the orchestrator you already have.
- Keep it when
- You need paginated, print-ready layouts such as invoices or statements on letterhead.
DRE vs Excel macros and manual exports
- What it does well
- Nothing to install, and the person who needs the report can build it.
- Where it gets hard
- It depends on one person and one laptop. Steps get skipped, numbers get pasted over, and nobody can see what changed between months.
- How DRE differs
- The same workbook every time, produced on a schedule from SQL anyone can review, and delivered without anyone remembering to send it. DRE can even fill your existing branded Excel template.
- Keep it when
- The report is a one-off, or the analysis itself is the work and changes every time.
Where DRE fits
DRE is for reports that recur and have to arrive in an exact shape: a finance pack, a file for a bank or regulator, an extract for another system, one report per client or region. It is not a dashboard tool, a transformation tool or a scheduler, and it works next to all three.
