1. Proses pembuatan tabel C1

2. Proses pembuatan tabel C2
TRecord = mysql_querySELECT a.,b. FROM barang a, support_apriori b where a.id_barang=b.id_barang and b.nilai_support = min_support
order By a.id_barang ASC or diemysql_error;
j=1; whiledata=mysql_fetch_arrayTRecord
i=data[id_barang]; TRecord2 = mysql_querySELECT a.,b. FROM barang a,
support_apriori b where a.id_barang=b.id_barang and b.nilai_support = min_support order By a.id_barang ASC or
diemysql_error;
whiledata2=mysql_fetch_arrayTRecord2{ id_barang2=data2[id_barang];
nilai_support = min_support;
ifi=id_barang2{
sql_cek_kombinasi = mysql_querySELECT FROM kombinasi_apriori WHERE id_barang=i and id_kombinasi=id_barang2
and support_count=nilai_support; ifmysql_num_rowssql_cek_kombinasi{

3. Proses Pembuatan Tabel L1
distinc_transaksi = mysql_queryselect countdistinctkode_transaksi as jum_transaksi from transaksi_barang
where kode_transaksi = jum_transaksi; array_count_transaksi = mysql_fetch_arraydistinc_transaksi;
TRecord = mysql_querySELECT FROM kombinasi_apriori order By id_kombinasi ASC or diemysql_error;

id2=data[id_barang];
sql_transaksi = mysql_querySELECT count as jum_trans from transaksi_barang where id_barang INid1,id2 and kode_transaksi =l
and kode_transaksi = jum_transaksi; array_transaksi = mysql_fetch_arraysql_transaksi;
