            This Hierarchical Model used Proper Hardware Maintenance data where in the model in the lower levels are sorted under a hierarchy of successively higher-level units. The Proper Hardware Maintenance data are grouped into clusters at one or more levels, and the influence of the clusters on the data points contained in the datas from the hardware maintenance is taken account for the other statistical analysis. In this example, the top-most of the heirarchy table is the Computer Hardware Maintenance, therefore it is where the other topics branch out from to extend to other topics that are still covered by hardware maintenance.

            This Relational Model (RM) represents the database of Proper Hardware Maintenance,this relation is a table of values about proper hardware maintenance of a software. Every row in the table represents a collection of related data values. These rows in diagram denote a real-world entity or relationship of factors that affect the proper maintenance of a computer. The elements are helpful to interpret the meaning of values in the diagram, giving sense as to why a certain entity influence another. The data are represented as a set of relations. In this relational model, the Proper Hardware Maintenance diagram units are stored in a diagram. However, the physical storage of these data are independent of the way the data are logically organized as it is a relational model.

            This Network Model is a database model that used Proper Hardware Maintenance and is designed as a flexible approach to representing objects and hardware maintenance relationships. This network model also has its schema which is viewed as a graph where relationship types are arcs and object types are nodes. Unlike other database models, the network model's schema is not confined to be a lattice or hierarchy; the hierarchical tree is replaced by a graph, which allows for more basic connections with the nodes. This model is also used to distinguish the relationship as a network between Proper Hardware Maintenance and its other specific branches
