CLUSTER DATABASE-DIAGRAMS-ENTITY · 21 ENTRIES · EARLIEST ENTRY 2018-07-31

Database ER diagram generators

This cluster consists of tools for creating, visualizing, and reverse-engineering database entity-relationship diagrams, frequently with SQL or ORM code export. Pre-index dated entries appear sporadically across ་2010, 2015, ་2018,་ 2020, and ་2026, with single or double entries per year and no sustained pattern, indicating a thin, irregular entry history. The top traction signal among tracked members is pomai-diagram-app with ་2 stars, while other listed members have 0 stars.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
