134 Sun Java System RFID Software 3.0 Administration Guide February 2006
FIGURE 7-1 Sun Java System RFID Information Server
Alternatively, you can consider the EPC-related tag data as being either static or
timestamped. Static data includes the serial-level and product-level properties of
tagged items, such as the GTIN number of a box of detergent. Timestamped data is
collected over a period of time and typically changes more often than static data. An
example of timestamped data is the relationship between an EPC and a business
transaction, such as an advance shipment notice.
The RFID Information Server is deployed on one of the supported J2EE-compliant
application servers. Other applications can interface with the RFID Information
Server through XML message exchange. The RFID Information Server also supports
HTTP and Java Message Service (JMS) API message transports. The RFID
Information Server stores all data in a relational database management system
(RDBMS). The RFID Information Server has been tested with Oracle 9i Database,
Oracle 10g Database, and PostgreSQL 8.0.4.
Note EPCGlobal has recently chartered a working group to define the
specifications for an EPC Information Server (EPCIS). Sun actively supports and
monitors the activities of the working group and participates in the endorsement the
specifications as they become final. EPCIS is the industry term for middleware such
as the Sun Java System RFID Information Server.
RFID Database Information Tables
The RFID Information Server stores EPC-related information in database tables that
include the following:
Product-level and serial-level data This data is captured in the
ORGANIZATION, PRODUCT and UNIT tables.
These tables have a hierarchical relationship. Each PRODUCT is linked to an
ORGANIZATION through the ORGANIZATION_ID attribute. Similarly, each
UNIT is linked to a PRODUCT through the PRODUCT_ID attribute.
