+# dataui
+A set of tools which auto generates frontend ui and backend data operation for data in table in database.
+
+## crud
+crud module generates crud UI for data in table in database.
+base on a description json file, this module wll generate code by a parameter:
+* browser: genrates the data browser UI
+* filter: generates the filter condition input UI
+* add: generates the new data input UI
+* edit: generates the data modify UI
+* remove: generates the delete data UI
+* choose: browser data for choose, has filter UI.
+* insert:generates the new data insert backend script;
+* update:generates the update data backend script
+* select:generates the query data backend script
+* delete:generates the delete data backend script
+
+## tree
+tree module generates tree UI for hierarchy data in table in database.
+
+a plugin for gadget webserver, it generates data browser
