In this dissertation we investigate the usage of a known data mining technique, frequent sequence mining, for correlating database accesses in storage systems. We look at I/O prefetching as an application of disk block correlations. We design, implement and compare dynamic and static block correlation mining techniques. For the static techniques, we study schemes with and without correlation rule retraining.In our experimental evaluation, we use the MySQL database engine and two applications: DBT-2, a TPC-C-like benchmark and the RUBiS auctions benchmark. We perform the mining at the storage level and measure the respective application hit rates in the storage cache. Our results show that, by using block correlations, we can improve the storage cache hit rate by 3-21% for DBT-2 and 5-47% for RUBiS, compared to the baseline. Furthermore, we show that dynamic mining outperforms static mining in terms of higher hit rates and more accurate block correlation rules.

What's New in Oracle Database Storage Administration? New Automatic Storage Management Features for Oracle Database 11 g Release 1 () 1 Introduction to Automatic Storage . Better Security - In a modern relational database, I can allow a user access to only part of the data. I could restrict access to sensitive data such as social security numbers while still . 6 Managing Database Storage Structures. Logical structures are created and recognized by the Oracle database server, and are not known to the operating system. The primary logical structure in a database, a tablespace, contains physical files. Data blocks, also called database blocks, are the smallest unit of I/O . Sizing storage systems for SQL Server can be challenging because I/O characteristics differ significantly between applications depending on the nature of the access patterns. The techniques in this paper will give you the tools you need to monitor and characterize I/O .

He’s the author of SQL Server Administration in Action, was a technical editor on the SQL Server MVP Deep Dives book 3/5(3). The untethering of storage and its related I/O operations and wait states from the server supports an "appliance view" of storage in an distributed computing context. We will conclude our Cited by: This paper focuses on server primary system memory and secondary storage technologies spanning the past, present, and future.
