 ## Automatic Insert/Search/Edit Generation
 The [dbadmin](https://github.com/ncannasse/dbadmin) project provides an HTML based interface that allows inserting/searching/editing and deleting `record-macros` objects based on the compiled `record-macros` information. It also allows database synchronization based on the `record-macros` schema by automatically detecting differences between the compile time schema and the current DB one.
