What is the difference between an object-oriented model and a relational database model?


Quick Answer

An object-oriented model uses objects containing stored values to unite the application and database development, while a relational model uses relations to construct data. The rational model is used to create grid-like mathematical structures while the object-oriented model is used to transform data into a unified data model.

Full Answer

Object-oriented modeling uses objects that contain stored values found within an object. It is the process of designing and preparing what the model's code looks like. Modeling techniques are implemented during construction. The three phases of object-oriented modeling are analysis, design and implementation. The main focus during the first stages of development is on the external details of the system. The primary focus shifts during the later stages of development onto understanding how the system functions. As the development process advances, the model becomes more detailed.

In a relational model, data is stored in tables. Each table includes rows, columns, a header and a body. The relational model also uses keys, which are specifically designated columns, to order or relate data in one table to data in other tables. Rules or integrity constraints are designated by the relational model to ensure data integrity. Normalization is also used to ensure data is stored more efficiently.
