Q2. Based on the BITS database, DBA creates the following un-normalized database table: Invoices (InvoiceNum, IDate, ClientNum, CLastName, CFirstName, Street, City, State, Zipcode, (TaskID. TDescription, TCategory, TPrice) ) DBA is considering to add invoices to the BITS database. Each invoice has a unique InvoiceNum. Each invoice belongs to only one client and has only one invoice date. Each invoice may cover many tasks, and each task may appear in many invoices. The relationship between invoice and task is many-to-many. This database is called BITS2. (A) Please list all the FDs that should exist in the above BITS2 database. FD1: InvoiceNum → Date. ClientNum. CLastName CEirstName, Street, City, State, Zipcode (B) Please list all the MDs that should exist in the above BITS2 database. MD1: InvoiceNum →→→ LaskID (C) Based on all the FDs that should exist, please convert this unnormalized table into an equivalent set of tables that are in 4NF. You must underline the primary key field(s) and show any foreign key (EK) for each table
