在这项研究中，我们研究了信息空间中对象之间复杂的结构化关系及其时变特性的管理方案。特别是，我们有促进对时变复杂对象的有效处理的方案、索引方案、存储方案和查询处理方案。更详细的研究内容如下：1.集合是各种复杂对象的基本构造器。对具有签名文件的集值对象的高效处理方案进行了研究和评估。开发并评估了带有签名文件的多级嵌套复杂对象的处理方案。以化学光谱为例，研究了基于特征文件技术的高效光谱检索处理方案。研究了结构化文档等半结构化复杂对象的管理方案。开发并评价了复杂对象拼接的优化方案。已经研究了针对时变复杂对象的版本管理方案。此外，还设计并实现了一种可视化的查询语言来对它们进行操作。作为时空复杂对象管理的基础存储系统，设计并实现了一个时态持久存储系统，并对其基本性能进行了研究。

In this research, we have investigated schemes to manage complex structured relationships among objects in the information space and their time-varying properties. In particular, we have schemes to facilitate efficient processing of time-varying complex objects, indexing schemes, storage schemes and query processing schemes. More detailed research issues are as follows :1. Sets are basic constructors for various complex objects. Efficient processing schemes for set-valued objects with signature files have been investigated and evaluated.2. Processing schemes for multi-level nested complex objects with signature files have been developed and evaluated.3. Taking chemical spectra as examples of sequential complex objects, efficient processing schemes for spectra retrieval based on the signature file techniques has been studied.4. Management schemes for semi-structured complex objects such as structured documents have been investigated and studied.5. Optimization schemes for joining complex objects have been developed and evaluated.6. Version management schemes for time-varying complex objects have been investigated. Also, a visual query language for their manipulation has been designed and implemented.7. As a base storage system for spatio-temporal complex object management, a temporal persistent storage system has been designed and implemented, and its basic performance has been studied.
