Please provide a description of the model that comes to mind when you hear the words "Verification and Validation Model

Why is it necessary to divide the data into training and validation sets? What will be the purpose of the training set? What is the purpose of the validation set?

Indicate some possible quantitative rewrites of the following criteria. You are free to use whatever measurements you choose to express the requirements.

What is "point of view"? What's "view"? Does a view definition's data always appear in its description's type? Views effect database data input.

I need to double check my answer to insure I did it right. Thanky you.  Question:  Gamer:                            (UserID, Name, Age, Address, City, Favorite-Game, Rank) Game:                             (GameID, Name, Company, Release-Year, Version) Store:                              (StoreID, Name, Address, City) WhereToFind:                 (GameID, StoreID, Price) Category:                        (GameID, Category-Name)  From the relational schemas illustrated above, use the different relational algebra operators and operations (ρ, σ, π, ⋂, ⋃, -, ⨝) discussed in class to build the following queries: 1. List -by name and ID- each gamer who lives in the city of Chicago, with a rank of 5, and is aged between 15 (included) and 30 (included).2. List games -by name and release year- that are not in the “Action” category.3. Since each game can fall within several categories, list games -by name and release year- that are in the “Action” category and also in the “Role-Playing” category…

Please follow this ER diagram, give a description, and make a schema diagram from it. Also, make database (constraint tables) & intent some sample data. Lastly, run some SQL functions code.   Please don't copy from anywhere. I need it for my project.

Set up some space between the checking and the validating steps. Tell me some specific examples.

There is a great deal of flexibility in how keys are disseminated. Explain what's best and why it's the finest.

What is metadata, exactly? For a result set, what is metadata? Result set information might be helpful in some situations.

using the design file in the image attached to the question : Normalize the database in the design file Be aware of the possibility of duplicate data.
