The Model-View-Controller design pattern is utilised to maintain a clear separation between data access, business logic, data presentation, and user interaction. Moreover, it differentiates between the exhibition of data and the engagement of users. Please provide an explanation for discussion or analysis.

Direct connections between external entities and the database are not permitted under any circumstances. It should be kept in mind as one of the data flow diagram design concepts to consider. What do you think the repercussions of this suggestion will be?
Please explain good data input field foundations. What situations warrant breaking these norms?
Data access, business logic, data presentation, and user interaction are all kept distinct using the Model-View-Controller design pattern. Additionally, it distinguishes data presentation from user interaction. Discuss or provide your thoughts on this explanation.
During the process of conceptual data modelling, what are the four various kinds of E-R diagrams that are built and examined, and what is the purpose of doing so?
No external sources may establish a direct link to the database. It's a consideration for any data flow diagram creators out there. What does this suggestion imply?
What is the difference between a data entity (data model) and an external entity (process model)?
The Model-View-Controller design pattern separates data access from business logic, data presentation from user interaction, and user interaction from data presentation. Discuss or provide an explanation.
Data access is separated from business logic by the Model-View-Controller design pattern, as is user interaction from data display and data presentation from user interaction. In addition to this, it separates the display of data from the interaction with the user. Within the scope of this explanation or conversation, explain or provide.
Please provide a description of the best practices for developing excellent data-flow diagrams.
To begin, what are the key distinctions between developing a data model from scratch and using one that has already been pre-packaged?
