As we see in the table below, the data is atomic and hence already in 1st normal form.BoatNameMakeModelLengthOwnerLastNameOwnerFirstNameOwnerPhoneAddressCityStateZIPCharterDateCustomerNameAmountFar HorizonCatalinaMorgan38PrincetonDarryl206-543-66772345 15th NESeattleWA9811521-Jun-12Smith, Sally5,000.00$ Ebb TideHunter3838TulsaBill503-486-87861324 24th NEPortlandOR9721521-Jun-12Sailors, Mike5,500.00$ Far HorizonCatalinaMorgan38PrincetonDarryl206-543-66772345 15th NESeattleWA9811528-Jun-12Tully, Jason5,000.00$ Far HorizonCatalinaMorgan38PrincetonDarryl206-543-66772345 15th NESeattleWA981154-Jul-12Atkins, Merle5,000.00$ Foreign ShoresHans Christian38 MK II38BerkelyGeorge425-765-44554567 35th WBellevueWA980404-Jul-12Smith, Sally6,000.00$ Seafarer VEndeavour3737TulsaBill503-486-87861324 24th NEPortlandOR972154-Jul-12Travis, Chet4,500.00$ Seafarer VEndeavour3737TulsaBill503-486-87861324 24th NEPortlandOR9721518-Jul-12Watson, John4,500.00$ Midnight on the WaterSabre3232OxfordKelly503-578-75742435 36th SEAstoriaOR9710318-Jul-12Renborn, "Doc"4,000.00$ Ebb TideHunter3838TulsaBill503-486-87861324 24th NEPortlandOR9721527-Jul-12Sailors, Mike5,500.00$ Foreign ShoresHans Christian38 MK II38BerkelyGeorge425-765-44554567 35th WBellevueWA9804027-Jul-12Tully, Jason6,000.00$ 2ND NORMAL FORM2nd normal form deals with removing the partial dependency on the primary key. Thus we need to split the table further to remove any partial dependency.Table boatBoatName (primaryKey_) -> Make, Model, LengthTable ownerOwnerPhone (PrimaryKey_) -> (OwnerLastName, OwnerFirstName, Address, City, State, ZIP)Table ZipZIP (PrimaryKey_) -> City, StateTable boat_charter_infoCharterDate, BoatName, CustomerName (PrimaryKey_) -> Amount
