2. consider the following normalized relations for a sports league and assume that the database is global in scope and covers thousands of leagues, tens of thousands of teams, and hundreds of thousands of players. team(teamid, teamname, teamlocation, teammanager, teamleague)player(playerid, playerfirstname, playerlastname, playerdateofbirth, playerspecialtycode, teamid)specialty(specialtycode, specialtydescription, salary)location(locationid, cityname, citystate, citycountry, citypopulation) manager(managerid, managername)league(leagueid, leaguename, leaguelocation)a. do you see any denormalization opportunities? b. what are the first steps that you can take to improve the performance of the database? c. specify the types of indexes you would recommend for each of the following situations: 1. reporting players by team using the team name 2. reporting players of a specific specialty using the specialty code. how is your answer different if the report is using specialty description as input? 3. reporting the players whose salary is above a specific value. 4. reporting teams and their players by cityd. do you see any partitioning opportunities based on the above queries?

This program should be a short piece of code that prints all of the positive integers from 1 to 100 as described more fully below. the program may contain multiple methods, and if using an oo language, should be contained within a single class or object. the program should be designed so that it begins execution when invoked through whichever mechanism is most common for the implementation language. â–ş print out all positive integers from 1 to 100, inclusive and in order. â–ş print messages to standard output, matching the sample output below. â–ş in the output, state whether the each integer is 'odd' or 'even' in the output. â–ş if the number is divisible by three, instead of stating that the number is odd or even, state that the number is 'divisible by three'. â–ş if the number is divisible by both two and three, instead of saying that the number is odd, even or divisible by three; state that the number is 'divisible by two and three'. â–ş design the logic of the loop to be as efficient as possible, using the minimal number of operations to perform the required logic. sample output the number '1' is odd. the number '2' is even. the number '3' is divisible by three. the number '6' is divisible by two and three.

Why is it uncommon for users to perform searches directly in database tables? a.)users are discouraged from interacting directly with tables because they might confuse tables with spreadsheets. b.) users are discouraged from interacting directly with tables because this may result in unintended changes to source data. c.)users do not have the technical skills required to perform searches directly in database tables. d.)users do not have the permissions required to perform searches directly in database tables.
