Act on a node object about to be shown on the add/edit form this is a node-type- specific hook, which is invoked only for the node type being affected see node api hooks for more information use hook_node_prepare() to respond to node preparation of all node types this hook is invoked from node_object_prepare(). On most form alters in drupal, you target a specific form based on the form id node forms are weird because the content type is included in the form id if you have a content type named example , the form id would be example_node_form in order to only alter a specific content type's node form, you can.
Adding and modifying database tables in update hooks to add a database in an update hook (may you not have to do that much) it appears you must borrow from the innards of drupal_install_schema() see in linkoutreadmoreinstall php / implements hook_update_n() / function. After the node information is read from the database or the entity cache, hook_load() is invoked on the node's content type module, then field_attach_load_revision() or field_attach_load() is called, then hook_entity_load() is invoked on all implementing modules, and finally hook_node_load() is invoked on all implementing.
