Place your answer after each question 1. The head DBA has requested the creation of a sequence for the primary key columns of the Criminals and Crimes tables. After creating the sequences, add a new criminal named Manie Capella to the Criminals table by using the correct sequence. (Use any values for the remainder of columns.) 2. A crime needs to be added for the criminal, too. Add a row to the Crimes table, referencing the sequence value already generated for the Criminal_ID and using the correct sequence to generate the Crime_ID value. (Use any values for the remainder of columns.) 3. The last name, street, and phone number columns of the Criminals table are used quite often in the WHERE clause condition of queries. Create objects that might improve data retrieval for these queries. 4. Would a bitmap index be appropriate for any columns in the City Jail database (assuming the columns are used in search and/or sort operations)? If so, identify the columns and explain why a bitmap index is appropriate for them. 5. Would using the City Jail database be any easier with the creation of synonyms? Explain why or why not
