In addition, The PACS system is equipped with a central core consisting of a 300-gigabyte central server; a set of 1.25-terabyte optical jukebox archive together with adjustable wavelet compression or PacsPro II that is an EMED Technologies, Lexington, MA; some workstations which are four-panel 2.5 2.0K monitors (average rate image display time is less than 2 sec/full-resolution computed radiography image. The Images in PACS system are routed to individual workstations based on the algorithm that applies a synthesis of patient location, image source, day of week, time of day, imaging type, and Common Procedure Terminology (CPT) code (Gale, Gale, Schwartz, Muse and Walker, 2000).
Oracle is a new networking infrastructures and applications that provides highly available integrated and high level of performance software components that meets the demands of most industries. The Oracle empowers applications with very
high throughput and instant responsiveness and performance-critical functions faster. The combination of programs are delivered on the data management requirements important to realize service agility like: Superior combination of batch performance and real-time for data located in call control as well as back office applications; Intelligent caching; Providing support geographically for "fail over" and load balancing; full adherence to standard interfaces; Easy manageability and low maintenance requirements; and non-stop operations capable of achieving carrier-grade availability (Oracle Corporation, 2007).
All PACS products (The Royal College of Radiologists, 2002) consist of database that can store information of patients, at the same time, cataloguing their imaging studies. Several PACS installations integrate and use a single relational Oracle databases to data storage. The user then, interacts instantly with the Oracle
