PRAKATA

Puji dan syukur penulis panjatkan kepada Tuhan Yang Maha Esa, berkat

karunia-Nya, sehingga kami dapat menyelesaikan skripsi dengan judul “Analisis Dan

Perancangan Data Warehouse Pada Software Laboratory Center Binus University” ini

tepat pada waktunya. Adapun skripsi ini dibuat sebagai salah satu syarat kelulusan pada

jenjang pendidikan Strata-1 jurusan Teknik Informatika pada Binus University, Jakarta.

Dalam penyusunan skripsi ini, penulis mendapatkan banyak dukungan dan

bantuan dari berbagai pihak, baik secara langsung maupun tidak langsung. Oleh karena

itu, penulis mengucapkan terima kasih yang sebesar-besarnya kepada:

• Bapak Prof. Dr. Gerardus Polla, M.App.Sc., selaku Rektor Universitas Bina

Nusantara.

• Bapak Ir. Sablin Yusuf, M.Sc., M.Comp.Sc., selaku Dekan Fakultas Ilmu Komputer

Universitas Bina Nusantara.

• Bapak Fredy Purnomo, S.Kom., M.Kom., selaku Ketua Jurusan Teknik Informatika

Uniersitas Bina Nusantara.

• Ibu Yen Lina Prasetio, S.Kom., M.CompSc., selaku Sekretaris Jurusan Teknik

Informatika.

• Bapak Satmoko Yudo, Drs., M.Eng., selaku dosen pembimbing yang telah banyak

memberikan pengarahan, saran dan motivasi kepada kami dalam menyelesaikan

skripsi ini.

• Bapak Win Ce, S.Kom., MM., selaku Software Laboratory Center manager yang

telah memberikan izin kepada penulis untuk melakukan survei di Software

Laboratory Center.

• Seluruh staf Software Laboratory Center yang telah banyak membantu dalam

memberikan informasi yang sangat bermanfaat dalam penulisan skripsi ini.

• Seluruh staf pengajar Jurusan Teknik Informatika Bina Nusantara yang telah

membimbing penulis selama kuliah.

• Orang tua beserta keluarga yang telah memberi dukungan moral maupun material

kepada penulis.

• Seluruh rekan dan pihak yang telah banyak membantu penulis dalam penyusunan
