Main post

Computer database management system can be termed as a software package created to fully

manage a business firm database. Numerous sorts of database management system wholly exist

on the basis of how the database manage the information stored. In this discussion two types of

database management system, i.e. hierarchical database and network data base management

system will be explained. According to the hierarchical database management system model, it is

like a tree structure identical to the folder architecture within the computer systems. The

connection amid the diverse records are predefined within one to one way, amid parent as well as

child nodes. One need to pass a hierarchy for them to fully access the information stored within

the system (Yunus, Krishnan, Nawi, & Surin, 2017). Hierarchical database management system

have numerous advantages such as it can promote complete sharing of information, the parent to

child connection often encourage conceptual simplicity, and the security of database is normally

offered and enforced by database management system. The parent to child relationship within the

database often promote integrity of information. On the other hand, hierarchical database

management system often have diverse disadvantages such as; the complex execution needs deep

knowledge of physical information storage features, the navigational scheme gives complex

software development, management as well as usage, all these diverse aspects needs insightful

knowledge of the database. Additionally, alterations within the structure need shift in all the

software program, and there is no definition of information or information manipulation languages

within the database management system. Lastly, the database system lack the standards during the

development of the system. The second network database management system model also possess

a hierarchical structure. (Yunus et al, 2017) The database system support many to many

connections, as child tables can possess more than a single parent. The core advantage of the

network database management system model is the many to many connection. The disadvantage

of network database system is that it lacks the structure that can resolve the many to many

connections amid the instances or records.

Hello, the student has provided a more detail information pertaining to the core discussion. The

information provide a more insightful data, and comprehensive explanation. To add, the main

concept behind the development of hierarchical database models is often important for some type

of information storage, however, it is not that extremely versatile. The database core limitation is

that it is only confined to a precise usage. To illustrate this where each person in a firm have the

chance to report to a precise department, therefore, the department can be employed as parent

record as well as the sole individual staff can fully represent secondary record, and each of which

will be connected to the sole parent through an hierarchical scheme. Hence, the hierarchical

database management system tend to generate the most where the core focus of data collection is

highly concrete hierarchy like list of firm sections linked to a precise high level core information

components (Kumarasamy, 2018).

On the other hand, the network database management system model often permit each and every

record to possess several parents as well as numerous child records within the firm, whenever

visualized, the record tend to form a web like scheme of the networked data. This key aspects of

having numerous connections tend to depend on two ways. The first scheme as well as the database

management itself can categorized as generalized graph of the records sorts, which are linked to

the association types. The core advantage of the network database management system is that the
