INFORMATION MODEL & DATA MODEL
The Information Model is a formal and concrete definition of the structure of information. It talks about how information is arranged in a certain area. It describes the information's relationships, how they are related, and what their important parts are.
Data Model on the other hand, is the more detailed version of the previous information model. It's where we exactly clarify how to structure and store data in a database. It provides which data complements each other and how they relate to each other.
The Network Model organizes data in a network of points connected by lines. Each point represents the history or records while the lines show how these records are linked. This model lets records have more than one connection.
The Relational Model is organizing data in a much more simplistic way using tables, rows, and columns. These rows contains information while each column contain a different detail about the said information. Lastly, these tables can be linked together and can be related.
The Hierarchical Model puts data in a tree-like structure. There is a root information which splits into smaller points which can also split into even smaller ones. Like a family tree, it provides clarity by having a clear order. However, its downside is that it's not for complicated stuff.
