面向空间应用的数据对象存储与检索系统研究

针对当前标准对象存储系统的数据对象属性存储和检索方面的不足，结合空间应用数据对象特点，进行了对象属性设计，提出了一种基于HBase数据库的属性管理方法。该方法利用HBase数据库对数据对象及其属性进行集中管理，同时采用分段散列索引实现利用对象属性快速检索对象数据。测试结果表明，基于HBase数据库对象管理方法性能优于现有的属性管理方法，具有较高的对象属性检索效率。

Research on Object Storage and Retrieval System for Space Application Data

In view of the shortcomings of the storage and retrieval of object attributes in the current standard object storage system, combined with the characteristics of spatial application data objects, the attribute of objects is designed, and HBase database, a new attribute management method, is proposed. This method uses the HBase database to centralize the data object and its attributes, and uses the segmented hash index to realize the fast retrieval of the object attributes. The test results show that the performance of object management method based on HBase database is better than the existing attribute management method, and has a high efficiency of object attribute retrieval.
