EnglishWhat do the leaderboards on dbdb.io show?
Updated
The leaderboards on dbdb.io are activity rankings for the database entries in the encyclopedia, updated daily. They answer a different question than the main catalog: not "what database systems exist," but "which entries people are adding, reading, and revising right now." The page lists three boards — Most Recent, Most Viewed, and Most Edited — and each measures a distinct kind of activity over a stated time window.
The three leaderboards
| Leaderboard | What it ranks | Time window | What the numbers mean |
|---|---|---|---|
| Most Recent | Newly modified entries | Not stated on the page | How long ago an entry was last changed (e.g., "3d ago") |
| Most Viewed | Entries with the most views | Last 30 days | A percentage change in views versus the prior period |
| Most Edited | Entries with the most edits | Last 30 days | A raw count of edits |
Each board also carries its own refresh cadence: the leaderboards as a whole are marked "Updated Daily," while the Featured System section is marked "Updated Weekly."
Reading each board
Most Recent
This board lists entries by how recently they were modified, with a relative timestamp. In the snapshot shown, OrioleDB and Turso (both Relational) were modified 3 days ago, Xodus (Document / XML) 9 days ago, voidDB (Key-Value) 9 days ago, and CnosDB (Relational) 10 days ago. Use it to see what the community is actively maintaining rather than what is merely popular.
Most Viewed
This board covers the last 30 days and pairs each entry with a percentage change. The percentages are the part most likely to be misread: a negative figure is a decline in views, not a rank or a rating. In the snapshot, Oracle (tagged Key-Value, Graph, Triplestore / RDF, Document / XML, and Relational) was down 26%, Derby (Relational) down 20%, Heroic (Key-Value) down 48%, DynamoDB (Document / XML, Key-Value) down 45%, and TileDB (Array / Matrix) down 1%. Because every entry in that snapshot shows a decline, the percentages are best read as relative momentum within the board, not as absolute traffic levels.
Most Edited
This board counts edits over the last 30 days. The snapshot shows SereneDB (Relational) with 2 edits, and CloverDB (Document / XML), CnosDB (Relational), ConceptBase.cc (Object-Oriented), and Dremio (Relational) with 1 edit each. Low counts are normal here — this reflects how much correction or expansion a given entry needed, not how important the system is.
What the leaderboards are useful for
- Finding actively maintained entries. Most Recent surfaces systems whose pages were just updated, which is a reasonable starting point if you want current information.
- Spotting attention shifts. Most Viewed with its 30-day percentage change shows which entries are gaining or losing reader interest.
- Judging entry maturity. A high edit count can mean an entry is being actively fleshed out or corrected; a low one can mean it is stable or simply neglected.
- Cross-checking tags. Entries on these boards carry data-model tags (Relational, Key-Value, Document / XML, and so on), so a leaderboard row doubles as a quick pointer into the model-based browsing on the site.
Limits to keep in mind
The boards measure activity on dbdb.io itself, not the real-world popularity, performance, or adoption of a database system. A system with few page views may simply be well documented and rarely needing a visit. The page does not state how views are counted, whether unique visitors are distinguished from repeat visits, or what the baseline period for the percentage change is, so treat the numbers as directional signals rather than precise metrics. The Most Recent board also gives no fixed window — only relative timestamps — so its ordering shifts continuously as entries are touched.
