“The researcher cannot find the data;
If he can find it, cannot access it;
but he doesn't know how good they are;
and if he finds them good
he can not merge them with other data”

THE PROBLEM:
The researcher cannot find the data;
If he can find it cannot access to data;
if he can, he can not read them;
if he can read them,
he does not know how good they are;
and if he finds them good
he can not merge them with other data

Service Oriented Architecture
•Service providers registersh services to a service broker.
•Service users find the needed service and get access key from a service broker
•With the access key, users bind to the service provider
•The result is a dynamic binding mechanism between the service users and providers

• The data life cycle consists of the acquisition and the usage parts
Usage Activities
Data Acquisition
Data Acquisition and Usage Activities(Select View Show, click to step through PPT)
• The acquisition part processes the sensory data by firmly linked procedures
The focus is on data usage activities
• The usage activities are more iterative, dynamic procedures
• The collected and cleaned data are stored in the repository
DataRepository
• The usage cycle transform data into knowledge for decision making
