While concern about data “doubling each year” is a common IT refrain, there may be signs that it is not quite that bad. According to the results of a recent online survey by Unisphere Research, a division of Information Today, Inc., in which 461 database professionals participated, 63.8% of respondents’ companies experienced 0-24% data growth last year. Also, according to the survey, 16.2% of respondents’ organizations had data growth of 25-49%, and only 7.1% had data growth of 50-100% last year. At the extremes, 9.5% of respondents’ companies had no increase or decline, and 3.4% had data growth of more than 100%.
For the current year, 60% of respondents anticipate data growth of 0-24% at their companies, while 20% of respondents anticipate data growth in the neighborhood of 25-49%, and 11% expect data growth in the 50-100% range. At the far end of the spectrum, 6.2% of respondents expect no increase or decline, and 4.8% expect data growth of more than 100%.
The survey was conducted in conjunction with GoldenGate Software, a leading provider of high availability and real-time data integration solutions.

Big Red: About Oracle, its database, and other related topics
From archive: March 2009 X
The confangled gadget Jeremy Schneider is referring to is Oracle "Services". I read his paper today entitled, Unleashing Oracle Services: A Comprehensive Review of "Services" in Oracle Databases. On his site, Jeremy says, "This is an in-depth research paper summarizing several months of research about Oracle Services." Also, here is the abstract description:
Performance management and high availability have become base requirements for today’s enterprise relational database management systems. In Oracle databases users create “services” to meet these challenges and those services touch almost every aspect of database configuration. This paper presents a broad yet thorough exploration and explanation of every aspect of services for both single instance and cluster (RAC) databases.
Dan Norris considers this "the definitive whitepaper" on the topic. After reading it, I agree with Dan. It does appear that Jeremy published this just before Oracle Database 11g was released. However, the information in this paper is excellent and relevant for all database versions. If you are using 11g, you can always read about the changes or enhancements that 11g brought to Services in the New Features Guide.
Jeremy, thank you for sharing your several months of research on this confangled gadget![Read More]
