If we observe each of the entity they have parent –child relationship. 1. Because every business is different, here are the advantages and disadvantages of a centralized database to consider. Projection transformation can be done smoothly. As it is arranged based on the hierarchy, every record of data tree should have at least one parent, except for the child records in the last level, and each parent should have one or more child … Graphic output is usually more aesthetically pleasing … Parent/child relationship promotes conceptual simplicity. Cost estimation models are a well-known sector of data and process management systems, and many types that companies can use based on their business models. Hierarchical Database Model, as the name suggests, is a database model in which the data is arranged in a hierarchical tree edifice. Conceptual simplicity is at least equal to that of the hierarchical model. Faster development - Because of division of work web designer does presentation, software engineer does logic, DB admin does data model. Disadvantages. 2.
