Konsep Baru Pemodelan Database dengan Anchor Modeling

1. Konsep Baru Pemodelan Database dengan Anchor Modeling Bowo Prasetyo Contoh Kasus Lanjutan Perubahan Struktur dan Konten Database 10 Desember 2011 http://www.scribd.com/prazjp http://www.slideshare.net/bowoprasetyo

3. Berbasis pada empat konstruksi permodelan: anchor , attribute , tie dan knot .

4. Hasilnya dapat diterjemahkan ke desain relational database, di mana hampir semua tabelnya akan berada pada bentuk sixth normal form (6NF).

6. Perubahan Database 3 Perubahan Struktur dan Konten Mencatat Lokasi

10. Berarti tambah anchor baru yang sesuai, dengan satu attribute untuk IP address.

14. Tambahan satu attribute : LO_IPA_Location_IpAddress

15. Tambahan dua tie : GE_wasSaid_LO_at (bersejarah), US_was_LO_at

17. LO_Location ,

18. LO_IPA_Location_IpAddress,

19. GE_wasSaid_LO_at dan

20. US_was_LO_at.

21. Table Creation SQL CREATE TABLE lo_location ( LO_ID int(11) NOT NULL AUTO_INCREMENT, PRIMARY KEY (LO_ID) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci AUTO_INCREMENT=1 ; CREATE TABLE lo_ipa_location_ipaddress ( LO_ID int(11) NOT NULL, LO_IPA_Location_IpAddress varchar(15) COLLATE utf8_unicode_ci NOT NULL, PRIMARY KEY (LO_ID), UNIQUE KEY LO_IPA_Location_IpAddress (LO_IPA_Location_IpAddress) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

22. Table Creation SQL CREATE TABLE ge_wassaid_lo_at ( GE_ID int(11) NOT NULL, LO_ID int(11) NOT NULL, GE_wasSaid_LO_at_ChangedAt datetime NOT NULL, PRIMARY KEY (GE_ID,LO_ID,GE_wasSaid_LO_at_ChangedAt), KEY LO_ID (LO_ID) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci; CREATE TABLE us_was_lo_at ( US_ID varchar(64) COLLATE utf8_unicode_ci NOT NULL, LO_ID int(11) NOT NULL, PRIMARY KEY (US_ID,LO_ID), KEY LO_ID (LO_ID) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

23. Table Creation SQL ALTER TABLE `lo_ipa_location_ipaddress` ADD CONSTRAINT lo_ipa_location_ipaddress_ibfk_1 FOREIGN KEY (LO_ID) REFERENCES lo_location (LO_ID); ALTER TABLE `ge_wassaid_lo_at` ADD CONSTRAINT ge_wassaid_lo_at_ibfk_2 FOREIGN KEY (LO_ID) REFERENCES lo_location (LO_ID), ADD CONSTRAINT ge_wassaid_lo_at_ibfk_1 FOREIGN KEY (GE_ID) REFERENCES ge_greeting (GE_ID); ALTER TABLE `us_was_lo_at` ADD CONSTRAINT us_was_lo_at_ibfk_2 FOREIGN KEY (LO_ID) REFERENCES lo_location (LO_ID), ADD CONSTRAINT us_was_lo_at_ibfk_1 FOREIGN KEY (US_ID) REFERENCES us_user (US_ID);

25. Waktu pengucapan salam ( tie GE_wasSaid_US_by_ChangedAt )

29. JOIN ge_wassaid_lo_at ge_lo ON ge_lo.GE_ID = ge.GE_ID AND ge_lo.LO_ID = lo.LO_ID AND ge_lo.GE_wasSaid_LO_at_ChangedAt = ge_us.GE_wasSaid_US_by_ChangedAt

40. Pertama buka transaksi database.

42. Insert lokasi dan waktunya di tabel tie .

43. Terakhir tutup transaksi database.

44. Mengecek Lokasi di Tabel Attribute <sql:transaction dataSource="jdbc/security"> <sql:query var="loId"> SELECT LO_ID FROM lo_ipa_location_ipaddress WHERE LO_IPA_Location_IpAddress = '${pageContext.request.remoteAddr}' </sql:query>

45. Meng insert Lokasi di Tabel Anchor <sql:update var="inserted"> INSERT INTO lo_location (LO_ID) VALUES (NULL) </sql:update>
