医院信息系统的数据文件、索引文件、LOB型数据分离方法

摘要

In view of the shortcomings of conventional management for the HIS (Hospital Information System) database, the methodology for Oracle database management was deployed so as to make the data, indexes and LOBs (Binary Large Object) segregated and constantly stored in respective ifles. This practice has contributed to hierarchical storage management of the database in a more secure and intuitive way and made the dataparallelly accesse data faster speed.%针对医院信息系统（HIS）数据库传统管理模式的弊端，结合Oracle数据库管理特性，将数据、数据索引、大二进制数据对象分离，并连续存储于系统不同数据文件中，提高了数据库对象分层存储的清晰度和安全性，同时也提升了数据并行访问的速度。
