Penambahan Fungsi DW

Mengadopsi Banyak Tipe Data

3

Visualisasi Data

Parallel Processing (hardware)

4

Parallel Processing (Software)

� Menganalisa banyak task untukmengidentifikasi unit yang independent agar dapat di proses dalam urutan yang tepat(parallel)

� Mengidentifikasi unit2 kecil dan memastikandapat dieksekusi sesuai urutan

� Mengeksekusi unit independent dandependent sesuai urutan masing2

� Collecting, collating, dan consolidating hasilproses

Keuntungan Parallel

Processing

� Mampu menaikkan Performance dari query processing, data loading, dan index creation

� Tetap dapat digunakan walaupun adapenambahan perangkat tanpa aplikasi yang sedang dijalankan

� Tatap dapat berfugnsi walaupun beberapaperangkat paralell lain gagal bekerja

� Single logical view of the database even though the data may reside on the disks of

� multiple nodes

5

Query Tools

� Flexible presentation—Easy to use and able to present results online and on reports in many different formats

� Aggregate awareness—Able to recognize the existence of summary or aggregate tables and automatically route queries to the summary tables when summarized results are desired

� Crossing subject areas—Able to cross over from one subject data mart to another automatically

Query Tools (cont)

� Multiple heterogeneous sources—Capable of accessing heterogeneous data sources on different platforms

� Integration—Integrate query tools for online queries, batch reports, and data extraction for analysis, and provide seamless interface to go from one type of output to another

� Overcoming SQL limitations—Provide SQL extensions to handle requests that cannot usually be done through standard SQL
