Oracle Top Trends in DBMS & DW Noel Yuhanna Principal Analyst Forrester Research
Trend #1: Proliferation of data Data doubles every 18-24 months for critical Apps, for some its every 6 months Terabyte databases have become common, and in about 3-4 years the largest databases will be in Petabytes Driver for data growth:» Globalization» RFID data» Unstructured data» More detailed summarization/aggregation Growing trends on:» Compression» Granular level of partitioning» Virtualization of infrastructure» Consolidation on databases/ data warehouses» Archive data
Trend #2: Real-time Data warehouse Need for quick decisions business users can t wait days or even a day for data. Slow data movement ETL, replication, and batch loading need to reduce latency (Disk/IO) Competition is driving the need for real-time data warehouse High performance and scalable data warehouse architecture real-time Trends around:» Clustering/Grid technology to deliver performance and scalability» Appliances (data is closer to the processing)

Trend #3: Improve data security to prevent attacks and meet compliance requirements Enterprises struggle with data security databases and data warehouses Many do not take advanced data security measures such as data-at-rest encryption, auditing and security monitoring or masking Focus is shifting on stack-level security Applications and BI to data level Need for consolidation and automation requirement has grown tied to data security
Trend #4: Need for IT cost control Shrinking or stagnant IT budget is impacting new application deployment Database cost is a major concern for many besides increasing server, storage, and administration cost Many enterprises are focusing on Green IT to reduce power consumption Enterprises looking at consolidation, compression, archiving and standardization of databases and data warehouses. Focus is on using lower cost commodity servers, but concerns about its reliability still exists for missioncritical applications Need for maximizing resource utilization.
Best CPU vs. Disk performance: Gap exists CPU Disk CPU vs. Disk performance
Trend #5: Cached Databases & DW A key bottleneck in databases has been Disk I/O for many environments. Scalability perception few disks are good enough Memory/cache is cheap compared to a decade ago Forrester estimates that 20% of all OLTP and DW will be running completely in cache/in-memory by 2013.

Forrester Survey: Virtualization offers several benefits
Top five reasons to virtualize ROI 1. Utilize existing hardware and resources to its maximum capability, improve ROI for infrastructure 2. Minimize administration and improve operational efficiency 3. Lower IT cost licenses, people, server and storage 4. Improve SLAs for Applications 5. Offer a flexible architecture to support dynamic workloads and new type of applications.
