While mapping an object model to a relational database, we have two options for realizing inheritance: vertical mapping (using a separate table for the parent class) and horizontal mapping (duplicating columns). In which of the following cases you prefer vertical mapping? I. You anticipate that the parent class will change often in the future. II. Query response time is not a major concern. III. Run-time efficiency is the main design goal. IV. Modifiability is the main design goal. A Only III B II and IV C I, II, and IV D I and III E All of them

Think of a classification problem from your own experience and interest (e.g., distinguishingbetween two types of things/living beings/weather/personality/vehicle/industry/sports/houses/professionals etc.) Collect some real-world data to solve that classification problem. Have at least two classes, two attributes and atleast 5 instances per class. Create a dataframe with this data and paste a screenshot of it. Also give a short description of the data (number of instances, number of attributes and the list of attributes and list of classes). The attributes should be numerical. The classification problem should be a new one, but the dataset may contain data that are new (generated by you by any rough measurements) or collected from public domain. Please cite the references/sources from which you collect the data.
