+#### DB Graph Tasks
+
+These tasks are specific to database graphs. For these tasks there is a one time setup:
+
+```sh
+  $ cd deps/db && yarn install && cd -
+```
+
+* `dev:validate-db` - Validates a DB graph's datascript schema
+
+  ```sh
+  # One or more graphs can be validated e.g.
+  $ bb dev:validate-db test-db schema -c -g
+  Read graph test-db with 1572 datoms, 220 entities and 13 properties
+  Valid!
+  Read graph schema with 26105 datoms, 2320 entities and 3168 properties
+  Valid!
+  ```
+
+* `dev:db-query` - Query a DB graph
+
+  ```sh
+  $ bb dev:db-query woot '[:find (pull ?b [*]) :where (block-content ?b "Dogma")]'
+  DB contains 833 datoms
+  [{:block/tx-id 536870923, :block/link #:db{:id 100065}, :block/uuid #uuid "65565c26-f972-4400-bce4-a15df488784d", :block/updated-at 1700158508564, :block/left #:db{:id 100051}, :block/refs [#:db{:id 100064}], :block/created-at 1700158502056, :block/format :markdown, :block/tags [#:db{:id 100064}], :block/content "Dogma #~^65565c2a-b1c5-4dc8-a0f0-81b786bc5c6d", :db/id 100090, :block/path-refs [#:db{:id 100051} #:db{:id 100064}], :block/parent #:db{:id 100051}, :block/page #:db{:id 100051}}]

+
+* `dev:db-transact` - Run a `d/transact!` against the queried results of a DB graph
+
+  ```sh
+  # The second arg is a datascript like with db-query. The third arg is a fn that is applied to each query result to generate transact data
+  $ bb dev:db-transact
+  Usage: $0 GRAPH-DIR QUERY TRANSACT-FN
+
+  # First use the -n flag to see a dry-run of what would happen
+  $ bb dev:db-transact test-db '[:find ?b :where [?b :block/type "object"]]' '(fn [id] (vector :db/retract id :block/type "object"))' -n
+  Would update 16 blocks with the following tx:

+  With the following blocks updated:
+  ...
+
+  # When the transact looks good, run it without the flag
+  $ bb dev:db-transact test-db '[:find ?b :where [?b :block/type "object"]]' '(fn [id] (vector :db/retract id :block/type "object"))'
