What’s on the SQL vs NoSQL poster
Relational against Document / key-value, side by side.
- Relational: Schema defined up front
- Relational: Joins across tables are cheap
- Relational: Strong transactional guarantees
- Relational: Ad-hoc queries are easy
- Relational: Scales up more easily than out
- Document / key-value: Flexible or absent schema
- Document / key-value: Data denormalised into one document
- Document / key-value: Horizontal scaling is the design goal
- Document / key-value: Queries must be planned in advance
- Document / key-value: Joins are expensive or unavailable
- Modern relational databases store and index JSON. Modern document stores have transac…
Most applications that chose NoSQL for scale never reached the scale where it mattered — and paid for the missing joins daily.

- Who is the SQL vs NoSQL poster for?
- SQL vs NoSQL belongs to the Computing section rather than to a school year, because computing is not something one grade owns. Anyone learning data can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the SQL vs NoSQL poster?
- Choose by access pattern. If you do not know the queries yet, relational is the safer default. A wall chart earns its place by being glanceable from where the work is happening, so SQL vs NoSQL belongs on the wall where that computing work actually happens, within glancing distance, rather than filed away.
- What other posters go with SQL vs NoSQL?
- ACID, The CAP Theorem and Choosing a Chart sit alongside SQL vs NoSQL in the Computing section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.ACIDThe CAP TheoremChoosing a Chart
- Is the SQL vs NoSQL poster free to download and print?
- Yes. SQL vs NoSQL downloads as a free PDF with no account, no email and no watermark, like everything else in the Computing section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the SQL vs NoSQL poster print at?
- SQL vs NoSQL is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of SQL vs NoSQL loses nothing.Printing guide
