This is a question that I have and would like someone who has experiences with scene graphs and entity component systems to answer.For context, I am currently implementing a game engine and currently I am debating on our current design.Our current design is we have a singular game component class that every component inherits from. Where we have components like SpriteRendererComponent, Mehs Component, etc. They inherit from this GameComponent class. The point of this is being able to have O(1) access to the scene to being able to modify components to attach more components with the idea of accessing those components to specific scene objects in a scene.Now, my question is what kinds of caveauts can this cause in terms of cache coherence? I am well aware that yes its O(1) and that is great but cache coherence is going to be really bad, but would like to know more explicit details and real-life examples such as write in RAM examples on how this is bad. A follow-up question that is part…

Q4: Consider the following MAILORDER relational schema describing the data for a mail order company. (Choose five only). PARTS(Pno, Pname, Qoh, Price, Olevel) CUSTOMERS(Cno, Cname, Street, Zip, Phone) EMPLOYEES(Eno, Ename, Zip, Hdate) ZIP CODES(Zip, City) ORDERS(Ono, Cno, Eno, Received, Shipped) ODETAILS(Ono, Pno, Qty) (10 Marks) I want a detailed explanation to understand the mechanism how it is Qoh stands for quantity on hand: the other attribute names are self-explanatory. Specify and execute the following queries using the RA interpreter on the MAILORDER database schema. a. Retrieve the names of parts that cost less than $20.00. b. Retrieve the names and cities of employees who have taken orders for parts costing more than $50.00. c. Retrieve the pairs of customer number values of customers who live in the same ZIP Code. d. Retrieve the names of customers who have ordered parts from employees living in Wichita. e. Retrieve the names of customers who have ordered parts costing less…
