- Add a teal 'more' link pinned to each landing feature card's bottom-right, pointing at the relevant doc page (modes, the SQL echo, undo & history, query plans, the assistive editor). - Stop short inline code (flags like --all-rows) from breaking after a hyphen: white-space:nowrap on inline code only; block code in <pre> is unaffected and still wraps/scrolls.

RDBMS Playground is a cross-platform terminal app that gives you a safe
|
|
sandbox for exploring relational database concepts: tables, columns,
|
|
primary and foreign keys, relationships, indexes, queries, and query
|
|
plans. It is built for learning — from your first table to writing raw
|
|
SQL.

<Card title="Two ways to work" icon="seti:db">
|
|
Start in **simple mode** — a friendly, keyword-based command language —
|
|
and switch to **advanced mode** for standard SQL whenever you are ready.

<Card title="Learn the SQL underneath" icon="open-book">
|
|
Run a simple-mode command in advanced mode and the playground shows you
|
|
the equivalent SQL, so the bridge from concepts to SQL is always visible.

Every change can be undone, your work is saved as you go, and you can
|

rebuild the whole database from plain, readable files.

<Card title="See how queries run" icon="rocket">
|
|
Ask the playground to explain any query and it renders the database's
|
|
plan as an annotated tree — so indexes and scans stop being a mystery.

The input field completes commands with <kbd>Tab</kbd>, highlights

syntax, flags mistakes before you run them, and hints what comes next.
