Website database entity-relationship (ER) diagram shows the entities like occurrences, occurrence_attribute_value, titles, location_attributes_values, taxon_lists, and others. It is a high-level data model that defines data elements and their relationship for a specified software system. These ER diagrams for an elaborative website database can be created using EdrawMax or EdrawMax Online as it has several predefined templates that make the designing very easy. These entities have attributes like location_id, location_attributes_id, text_value, int_value, data_start_value, date_end_value, deleted, website_id, parent_id, and others. As the below ER diagram illustrates, an affiliation exists between various qualities of an element.
