1. Distributed Data Management Graeme Kerr Oracle in R&D Programme

2. Distributed Data Management Provides access to data when and where you need it Optimizes information access regardless of physical location of data. Enables virtualisation of data in Grids. Types of Data: Flat Files, Relational. Structured & unstructured. Text, Binary, proprietary. Scalar, user defined typed, XML, RDF Images, DICOM, LOB, Spatial. High Volumes.

3. Methods of Data Distribution Distribute Federate Consolidate

4. Distribute Information Share information between users, applications, databases, organisations and partners. Move or copy / replicate information as needed Traditionally implemented as replication or message queuing Wide range of technology solutions to achieving distribution. Continuous feed and periodic refresh capabilities are key requirements. Common within Scientific Grid Approach Works well when replicas are read-only. Considerable issues when replicas are updateable.

9. Methods of Data Distribution Distribute Federate Consolidate

10. Federate Information Federate data in multiple data stores into a single virtual database Access both Database and non-Database data Access both structured and unstructured data Hide physical location of data from applications Vendor and open-source solutions. Used mostly as point solution within Commercial World rather than as a key design point.

15. Methods of Data Distribution Distribute Federate Consolidate

16. Consolidate Information Consolidate heterogeneous data into a central pool. Single database or pool of databases Any data (audio, video, XML, email, messages, etc…) Any platform (Linux, Windows, Solaris, HPUX, AIX, Tru64, OpenVMS, OS/390) Proven scalability Hundreds of Very Large Database customers Industry leading benchmarks Very common in commercial world.

22. Distributed Data Management : Summary Oracle supports efficient utilization of all resources: Consolidate Information—Scalable access to large amounts of information Federate Information—Data can be located where needed but accessed as single database Share Information—Multiple users and applications can share data/information to operate more effectively Information Integration & fast connectivity critical to Grid Computing
