Answer 1

a couple of side observations ..
First, it is much easier to read code when it is (1) formatted, and (2) that formatting is preserved in the forum by use of the \ tag.CREATE
TABLE College
cName VARCHAR2(200) NOT NULL
, state VARCHAR2(20) NOT NULL
, enrollment INT NOT NULL (enrollment > 0);
CREATE
TABLE Student
sID INT NOT NULL
, sName VARCHAR2(200) NOT NULL
, GPA REAL NOT NULL CHECK(gpa >0 AND gpa < 4.0)
, sizeHS INT NOT NULL
, CONSTRAINT Primary_Key_SID PRIMARY KEY (SID)
CREATE
TABLE Application
sID INT NOT NULL
, cName VARCHAR2(200) NOT NULL
, major VARCHAR2(20) NOT NULL
, decision VARCHAR2(10)
NOT NULL CHECK
decision ='y'OR decision = 'n'
CONSTRAINT fk_Sid FOREIGN KEY (SID) REFERENCES Student(SID),
CONSTRAINT fk_Cname FOREIGN KEY(CNAME) REFERENCES college(CNAME));
Now,
First, drop the mixed case names.  Oracle isn't going to store them in mixed case in the dictionary, and if your force it to do so you just create bigger problems for yourself.  You may have learned mixed case in the MS world, but this is Oracle.  When in Rome
Second, you have a column named SID  (yes, you entered it as "sID", but to oracle it is SID.  And to oracle, it is a key word.  Find an alternative.
