Respond to the following in 300 words (Original topic: Discuss the differences, advantages, and disadvantages of BOTH Hierarchical databases and Network databases.)

Network Database: The network model is a database model that was developed as a practical manner of showing objects and their associated relationships. It organizes attributes as a schema, which is shown as a graph with nodes representing object kinds and arcs representing relations. It is not restricted to any hierarchy or grids.

Advantages: The major benefit of the NDBMS concept is that there are many to many links that facilitate the creation of real-world situations. It is straightforward and accurate in designing, exact access, and versatile in comparison to the hierarchical model; it limits the member in the apparent lack of a parent, necessitating the recording of the owner and subsequent member records to ensure the integrity of the data; it is also the right choice to identify programs from the accumulated tangible storage segments (Johanna et al., 2021).

Disadvantages: As whole records are managed via pointers, the overall database structure appears to be quite composite. This architecture requires a large number of pointer reconciliations to perform insertion, removing and updating operations on specific records, which appears to be extremely complex and confusing to implement. Since this is a navigating system, it is difficult to make structural changes.

Hierarchical Database: It is a technique for structuring databases that include one to many relationships. The concept is predicated on the notion that one parent can have several children in an environment in which only single parents are allowed. This enables the persistence of data via IBM-generated parent-child connections and was critical in the development of the equivalent IMF, the DBMS’s predecessor (Denisa, Nemec & Ude, 2017.

Advantages: This model enables accurate data insertion and removal. The data at the top of the hierarchy is extremely fast to reach. It is appropriate to use the model since it worked well with specific types of data storage, such as tapes. The approach is inextricably linked to conventional hierarchies, such as assembling plants and personnel management in a company.

Disadvantages: This model has a multitude of issues that held it back at the moment. We require more advanced connections. It necessitates the continual storage of data in a variety of distinct entities. When locating data on lesser entities, the data is modest. It may retain an excessive number of relationships, and many of these are not kept.

Differences:

· For storing data in a hierarchical database, the hierarchy approach is utilized. It is the oldest approach and is no longer used. While the network model integrates data via links and pointers.

· Data independence is a drawback of the hierarchical model. The network model is partially data independent.

· A hierarchical model utilizes a tree structure to arrange records. The network database arranges data into directed graphs.
