Which are important in object-relational databases, and how to translate the select-from-where cause into representations of monoid system are discussed. We take into account the onedimensional and multidimensional data partition methods, physical storage structures and further more how to parallelize them.

Parts of current parallel databases support expanding of data types, but all of them lack of theoretical foundation. It is difficult to predicate the performances of parallel query, complicated to optimize parallel query and unattainable to keep the correctness of parallel query optimization This thesis, for the first time, combines monoid algebra system with BSP parallel model systematically, and provides a general-purpose parallel object-relational database systems-PORDBMS.

Now keyword search over relational database is becoming a hot research topic in both database and IR area. There are two kinds of popular keyword search systems, while neither of them can give accurate results with high speed. The on-line system can obtain the latest search results while the search speed is low; The off-line system speeds the query processing by means of preprocessing, but the disadvantage lies in expensive cost needed to preprocess again once the database is updated.

Based on analysing the respective characteristics of regular PID controller in trational control theory and fuzzy logical controller in intelligent control theory, the idea and technique of expert system is introduced to develop a novel kind of hybrid intelligent controller. It can coordinate two kinds of control algorithms and tune the control parameters on-line for different working zones of the controlled process.(3) The hybrid knowledge expression model, which combines discrete state space model, fuzzy relational model and rule base model, is proposed based on analysing the characteristics of all kinds of knowledge expression models. The knowledge of the controlled process in different aspects can be expressed resonably by it. Based on the model mentioned above, the related optimization strategy for complex system is developed.
