6. Perangkat Utama Data center
• Perangkat Jaringan :
– Jaringan
– Router
– Switch-hub
• Media Penyimpanan
– Email server
– Webserver
– Database server
• Perangkat Listrik dan AC
– UPS
– Panel Listrik
– Grounding
Datacenter
7. Salah satu Disain Perangkat untuk Data center
Router
• Routing – adalah proses untuk memilih jalur
(path) didalam suatu jaringan yang harus
dilalui
– Router : perangkat yang melakukan
proses routing
• Pada umumnya skema routing
mempertimbangkan Jalur yang terpendek
dan jalur alternatif jika terjadi permasalahan
• Jalur yang baik, tergantung pada :
– Panjang data yang lewat
– Beban jaringan
– Pola trafik
8. Switch-Hub
Server
1. Server DNS (Domain Name
Server)
2. Server email
3. Server web
4. Server database
5. Server squid/proxy
9. Perangkat Listrik dan AC
1. Supply energy listrik
2. Genset
3. UPS
4. Panel listrik
5. AC
6. Jaringan listrik dan grounding
Perkembangan Telekomunikasi : ISDN
• Integrated Services Digital Network
(ISDN)
• What it is Terminal
Modem
– Transmission over standard Adaptor
ISDN
telephone wires
Line
– Peak rate 128 kb/s
– Available now
10. Perkembangan Telekomunikasi : Cable
• What it is: Simultaneous transmission over cable TV coax facilities
– Current technology - Cable modems @ Peak rate = 500 kb/s
– Available now
– Future technology: Digital TV + 10’s Mb/s
Perkembangan Telekomunikasi : Satellite
• What it is: Satellite access
– Asymmetric
– Requests are sent via modems
– Responses sent via satellite at
400 kb/s
– Available now
11. Perkembangan Telekomunikasi : HDSL
• What it is
– High-bit-rate digital subscriber line (HDSL)
– Peak rate ~10’s Mb/s
– Access over standard telephone copper wires
– In trials and limited deployment
Perkembangan Telekomunikasi : Wireless
Local Multipoint
Distribution System
(LMDS)
High Speed Wireless
Access for
- Telephone
- Video
- Internet
12. Perkembangan Telekomunikasi : Powerline Communications
• What is it:
– It is a data communication technology that operates over the electricity supply.
– Rates range up to 1 Mb/s
– In trials
– Future technology
Perkembangan Telekomunikasi : Costs (Estimated as of 2/98)
• Cable modem cost
– Installation ~ $25
– ~ $30/mo
• ISDN
– Installation ~ $200.00
– ~ $50 - $100/mo
• ADSL
– ~ $95/mo ( for 1.5 Mb/s )

• Satellite
– Hardware ~ $400
– ~ 24.95/month up to 64MB(approximately 25 hours online)
13. Sistem Informasi
Kenapa e-Gov
• eGov services are difficult to be
found
Problem addressed
? • Individual eGov services are
disconnected, not interoperable
• Citizens/Business have to find
several services, going then
from one to another
• No user guidance available
• eGov services do not comply
with e-accessibility criteria
• “One-stop-shopping” place where
all services can be located
• Identification of relevant
services based on life event
Approach
and business episodes
• User provided with a scenario
through structured workflow
• Virtual assistant assigned to
the user
• eGov services comply with e-
accessibility criteria

Data Warehouse/ODS & BI Layers
Data Integration Layer & Operational Data Store (ODS):
• ODS is a non queryable centralized staging areas for storing extracted, cleansing, and transformed data,
and for gathering centralized metadata for implementing an Enterprise Data Mart Architecture (EDMA),
eliminating the need for another non queryable staging area called data warehouse.
• Needed is a dimensionally modeled Data Warehouse for enterprise DSS, prepared to provide the best in
query response performance and to support the most advanced OLAP functionalities.
18. Data dan Informasi
Data
• type of data and Information
Data Represented by
Alphanumeric Data Numbers, letters, and other characters
Image Data Graphic images or pictures
Audio Data Sound, noise or tones
Video Data Moving images or pictures
Information = Data + Relationships
19. Information
• Characteristics of Valuable Information
•Accurate •Simple
•Complete •Timely
•Economical •Verifiable
•Flexible •Accessible
•Reliable •Secure
•Relevant
Meta data components
» Data name (entity, attribute, table, column, field, etc.)
» Business description of data (Project Start Date)
» Source of data (file, field)
» Business Owner of data
» Business rules
» Transformation rules
» Domains (allowable values)
» Data relationships
20. Meta data components (continued)
» Data quality (measure of reliability)
» Timeliness (ex: current as of certain date)
» Historical information
» Aggregation rules
» Security (who has access)
» Contoh :
[nama, usia, berat badan] = (Budi, 25, 60)
Sekarang jelas bahwa “Budi” adalah nama seseorang, “25”
adalah usia, dan “60” adalah berat badan
Meta data management
Meta Data = [Descriptive] Data About Data [of the Business]
• Meta data administration
• Business meta data
• Technical meta data
• ETL reconciliation
Information =
• Data quality metrics
Data within context
• Standardization Context =
Meta data
• Data ownership
Information =
• Enterprise integration
Data + Meta data
