By creating a very simple test case on a table with 100,000 rows of credit card data, and running a set of timed queries to select values from the columns, we are able to measure the effects of encryption versus a standard unencrypted query. It turns out that the query against encrypted data take[r]

Introduction

In 1983, RSI was renamed Oracle Corporation to avoid confusion with a competitor named RTI. At this time, the developers made a critical decision to create a portable version of Oracle (Version 3) that ran not only on Digital VAX/VMS systems, but also on Unix and other platforms. By 19[r]

After partitions are defined, certain operations become more efficient. For example, for some queries, the database can generate query results by accessing only a subset of partitions, rather than the entire table. This technique (called partition pruning) can provide order-of-magnitude g[r]
