摘要

数据密集型科学为信息技术特别是传统关系数据库提供了新的挑战和机遇。数据库文件系统提供了在同一数据库系统中存储0级数据和分析1级和3级数据的潜力。科学数据通常由非结构化文件和标量数据组成。Oracle SecureFiles是Oracle database 11g中的一个新的数据库文件系统特性，专门用于在Oracle数据库中存储非结构化或文件数据，提供高性能和可扩展性。SecureFiles为非结构化内容提供了最好的文件系统和数据库世界。存储在SecureFiles中的数据可以以与传统文件系统相当的性能水平进行查询或写入，同时保留Oracle数据库的优势。

A Case for Database Filesystems

Data intensive science is offering new challenges and opportunities for Information Technology and traditional relational databases in particular. Database file systems offer the potential to store Level Zero data and analyze Level 1 and Level 3 data within the same database system. Scientific data is typically composed of both unstructured files and scalar data. Oracle SecureFiles is a new database file system feature in Oracle Database 11g that is specifically engineered to deliver high performance and scalability for storing unstructured or file data inside the Oracle database. SecureFiles presents the best of both the file system and the database worlds for unstructured content. Data stored inside SecureFiles can be queried or written at performance levels comparable to that of traditional file systems while retaining the advantages of the Oracle database.
