Employee = Empid + Empname + SSN + Empadd + Empphone + DOB + Sex + DateHired + Lastdateworked + Averrating + WordProc + Typing + Filing + Bookkping + Steno + Availcode

Client = Clid + Clname + Cladd + Clphone + Contact + BillingYTD + PaymentYTD

Invoice = Invoice# + Invoicedate + Oldbal + Totcharges + Newbal + Totpaid + Clid*

Payroll = Check# + Paydate + Gross + Fed + Fica + State + Local + Net + Grossytd + Netytd + Fedytd + Ficaytd + Stateytd + Localytd + Empid*

Job-Employee = Job# + Empid + Ratername + Ratingdate + Emprating
