Eloquent object relational mapping models for biodiversity information system

Enterprise-scale applications are developed with an object-oriented approach, meanwhile, the widely used database management system now is a relational database, the mismatch between relational database and application development of the object-oriented concept is a problem between object-oriented environment with environment Relational Database Management System (mismatch impedances). This paper discusses the implementation of Eloquent Object Relational Mapping (ORM) for developing of Biodiversity Information System (BIS) and Model View Controller (MVC), which focuses on mapping the relations medicinal, wood, and tree object in the form of associations; One to One relationship, One to Many, Many to Many, Polymorphic Relations, Many Through Many, Many to Many Polymorphic Relations. The results of the implementation explain that the six concepts of association owned by Eloquent ORM can facilitate complex data relationships such as BIS by simplifying complex code writing to relate between tables by relating the class model so that it can be a solution to deal with complex data cases such as BIS. Eloquent ORM can mediate between the application layer and the database environment by transforming data from the relational database environment into object form and vice versa.
