Just a guess, maybe you’ve been reported for having an incorrect answer two times? I’m really not sure I’m just trying to give out possibilities. Maybe if your a Brainly Helper you haven’t been active so they are giving you warnings? Does clicking on the warning tell you the reason for them? Maybe the system thinks your a robot? I’m not sure just trying to give possible reasons, but you could try contacting customer support, but they aren’t always the quickest at responding.
Have a good day!
Answer:
Logical Data Model
Explanation:
An Entity Relationship Diagram (ERD) is a model or a diagram designed to reveal the relationship between various entities such as people, places, objects, and so on within an institution. Entity relationship diagram is also known as Entity relationship model. This model is used to design relational database by various sectors such as education, engineering, business, etc.
<u>ERD is designed using conceptual data model, logical data model, and physical data model</u>.
The visual practice or model that gives more insight into the logical relations among the entity is the logical data model.
The logical data model is used to illustrate more detailed operational and relational data among the entities. It is more detailed than the conceptual data.
So, the correct answer is logical data model.
Answer:
D. Late binding
Explanation:
a. early binding.
b. non-binding.
c. on-time binding.
d. late binding.
The compiler performs a process called binding when an object is assigned to an object variable. The early binding (static binding) refers to compile time binding and late binding (dynamic binding) refers to runtime binding. Another name for late binding is dynamic linkages
It is a computer programming mechanism in which the method being called upon an object or the function being called with arguments is looked up by name at runtime.
When a superclass variable refers to a subclass object and a method is called on that object, the proper implementation is determined at execution time. The process of determining the correct method to call is known as Late Binding.
