ISBN 978-1-847195-74-6

Competing in today's world requires a greater emphasis on strategy, long-range planning, and decision making, and this is why businesses are building data warehouses. Data warehouses are becoming more and more common as businesses have realized the need to mine the information that is stored in electronic form. Data warehouses provide valuable insight into the operation of a business and how best to improve it. Organizations need to monitor these processes, defne policy, and at a more strategic level, defne the visions and goals that will move the company forward in the future. If you are new to data warehousing in general, and to Extract, Transform, and Load (ETL) in particular, and need a way to get started, the Oracle Warehouse Builder is a great application to use to build your warehouse. The Oracle Warehouse Builder (OWB) is a tool provided by Oracle that can be used at every stage of the implementation of a data warehouse right from the initial design and creation of the table structure to ETL and data-quality auditing.

SQL Server Security Distilled, Second Edition (ebook)

by Morris Lewis 
ISBN:1590592190 
Apress © 2004 (352 pages) 


SQL Server is the dominant relational database in the Windows market and data security is a huge and growing concern for all businesses. Securing SQL Server is one of the most important responsibilities of the SQL Server professional. SQL Server Distilled, Second Edition is a very carefully researched, clearly explained book on securing SQL Server, by an author who knows SQL Server inside and out. If you follow the practical guidelines that are clearly set out in this book, then you stand a very good chance of making sure that the data stored in your database is secure and that the conversation between your applications and the database is secure (preventing SQL injection attacks, etc.). For example, any DBA who implemented the security precautions detailed in the book would not have been affected by the infamous Slammer virus. This second edition offers practical advice on how to implement good practices that will ward off future viruses before they are even created, and it contains new content that reflects all updates to SQL Server's security mechanisms.

Konsep Dasar Basis Data (pdf)

Pentingnya Data dalam Sistem Informasi

Konsep Dasar Basis Data
Sistem Informasi adalah pengelolaan Data, Orang/Pengguna, Proses dan Teknologi Informasi yang berinteraksi untuk mengumpulkan, memproses, menyimpan, dan menyediakan sebagai output informasi yang diperlukan untuk mendukung sebuah organisasi. (Jeffery L. Whitten dkk, 2004 ).
Apa itu Basis Data ?
Konsep Dasar Basis DataBasis Data, adalah mekanisme yang digunakan untuk menyimpan informasi atau data. Informasi adalah sesuatu yang kita gunakan sehari-hari ntuk berbagai alasan. (Stephens dan Plew ;2000), Dengan basisdata pengguna dapat menyimpan data secara terorganisasi. Setelah data disimpan, informasi harus mudah diambil. Cara data disimpan dalam basisdata menentukan seberapa mudah mencari informasi berdasarkan banyak kriteria. Data pun harus mudah ditambahkan ke dalam basisdata, dimodifikasi, dan dihapus.

  • Silberschatz, dkk (2002), mendefinisikan basisdata sebagai kumpulan data berisi informasi yang sesuai untuk sebuah perusahaan.
  • Menurut Mc Leod, dkk (2001), basisdata adalah kumpulan seluruh sumber daya berbasis komputer milik organisasi.

Functional dependencies - FD & Key (pdf)

 Pada file Pdf ini berisikan materi tentang :
  1. Decompotition 
  2. Key
  3. Normalization
Masalah Anomali :
  • Redundancy: Pengulangan informasi dalam beberapa tupel yang sebenarnya tidak diperlukan
  • Update anomalies: Pengubahan informasi dalam satu tupel yang tidak kompak (inkonsistensi).
  • Deletion anomalies: Kehilangan informasi akibat penghapusan informasi.
  • Insertion anomalies: Penambahan tupel baru yang tidak konsisten.
Teori Dasar :
  • Dekomposisi Relasi
  • Key
  • Ketergantungan Fungsional
Dekomposisi : memecah relasi/tabel menjadi relasi/tabel yang lebih kecil untuk mendapatkan skema yang tidak mengandung anomali dan redundansi ... (Lebih lengkap download dari link di bawah)

Resume Fungsional Dependensi (pdf)

Resume Fungsional Dependensi
Setelah membuat ER maka anda akan mentranslasikan ke suatu table, maka akan muncul
pertanyaan-pertanyaan sbb:
- apakah table anda bagus ?
- Skema yang jelek menyebabkan data redundancy
- Apa yang menyebabkan skema table anda jelek?
- Bentuk normal mana yang anda pakai BCNF atau 3NF
- Bagaimana jika skema sudah terlanjur jelek ?
- Dekomposisi ke dalam relasi yang lebih kecil yaitu ke bentuk BCNF atau 3NF

Disain Logikal adalah sebuah proses untuk memperbaiki skema DB yang didasarkan pada
penurunan functional dependencie (FD).
Idenya:
  1. Dimuai dari skema dasar yang diperoleh dari transformasi ERD
  2. Mengidentifikasi skema jelek dan mendekomposisinya ke dalam sekam yang lebih baik
Kegunaan disain logika adalah 
-  Menghindari data redundancy
-  Menhindari update anomaly
-   Menggambarkan data redundancy
-  Bagaimana cara menggunakan functional dependency
-  Bgaimana megkarakteristikan kualitas skema
-  Mendapatkan Bentuk normal
-  Mendapatkan skema yang lebih bagus, dengan algoritma dekomposisi

Normalisasi dan Fungsional Dependensi (pptx)

Definisi Normalisasi
Dipakai untuk membuat Relasi dalam Basisdata dengan tujuan mengurangi kemubaziran data.(E.F. Codd)Juga dipakai sebagai perangkat verifikasi thd tabel yang dihasilkan metodologi lainnya. Mencegah penciptaan struktur tabel yang kurang atau mengurangi ketidak efisienan. Proses merubah suatu relasi yang bermasalah ke dalam dua atau lebih relasi yang tidak bermasalah (Kroenke). Masalah==Anomali

Konsep Lossles-join Decomposition

  • Lossy (ada informasi yang hilang pada saat terjadi dekomposisi)
  • Lossless (tidak ada informasi yang hilang pada saat terjadi dekomposisi)
    Manfaat FD pada dekomposisi:
  • Lossless Join Decomposition
  • No Redundancy
  • Dependecy Preservation (Terjaminya pemeliharaan ketergantungan, utk mengatasi update Anomali)
