Considering the limited extensibility of the current data cleaning tools, this paper designs a rule driven data cleaning knowledge modeling to solve this shortcoming. The modeling improves the efficiency of data cleaning and ensures the quality of data. It describes the design of some key technologies of the modeling, such as rule base, cleaning strategy,… (More)
Considering the limited extensibility and the uneven capacity of the cleaning rule in current data cleaning work, this paper proposes an optimal cleaning rule selection model based on the machine learning. By establishing a cleaning rule performance evaluation system, the model realizes the optimal cleaning rule selection. It implements dynamic expansion of… (More)
The uncertain data objects in the MIS database structure design is a complicated issue and it's worth of discussing. In this paper, we observe the current existing solutions for the uncertain data objects and propose a new method that converts dynamic attributes modifications of the uncertain data objects to the records changing in a fixed-structure table.… (More)
Considering the advantages of the BLOB data type in the Oracle database, we design and implement the multimedia management by using the BLOB. In this paper, we describe corresponding database design, storage design and data operation design in detail. At last, it puts forward the corresponding code implementation.
This paper proposes the design and implementation of multimedia information management based on Oracle database and PowerBuilder. After describing the database structure design, multimedia information storage and editing method, multimedia information browsing method, it puts forward the corresponding code implementation.
