(e) Print all teamIDs where the team played against the Phillies but not against the Braves. 3. (15 points each) Write the following queries in relational algebra, using the schema provided above. (a) Define a relation Members(playerlD1, playerlD2, team) where playerlD1 and playerlD2 are (or have been) on the same team. Avoid listing self-references or duplicates, e.g. do not allow (1,1, Braves") or both (2,5, Phillies") and (5,2,"Phillies"). (b) Define a relation WorldSeries(teamID1, league1, teamID2, league2, date) where teamID1 and teamID2 played against each other in a World Series game. Although there is no direct information about the World Series in the relations, we can infer that when two teams from different leagues play each other, it is a World Series game. So, in this relation, league1 and league2 should be different leagues. (c) Define a relation AllLeagues(city) for which each city has a team in all leagues. For example, there are currently two leagues (National and American). Although not shown in this instance, New York is home to the Mets in the National league as well as the Yankees in the American league (Chicago also has one in each league, for those of you who are baseball fans). Remember that your query must work over all instances of this schema, even if there are more than two leagues in the instance Assign1.pdf Factory.java Design.with.Notes.pdf ^ SDLCDesign ReverseEngineerin pdf Show all | ^
