面向数据绑定的表格建模研究与实现

Research and Implementation of Table Modeling Oriented to Data Binding

表格作为结构化数据的一种最常用的表现形式,已被各个行业广泛应用在信息管理系统中。表格的自动生成和处理技术也成为应用信息系统设计和实现中的关键技术。随着Internet和Web技术的发展,Web与传统的数据库系统、文档管理系统结合在一起构成了巨大的、异构的、分布式的数据仓库。海量信息和异构信息的处理对表格的数据建模和处理技术提出了新的要求。针对现有技术在表格建模方面存在的模型结构简单,支持的表格类型有限和缺乏对集成异构数据源的支持等缺陷,本文在从设计和实现方面分析现有各种信息系统对表格处理技术的需求基础上,提出了一种面向数据绑定的新型表格建模方法以及相关技术,从而满足数据层和显示层在数据源类型、数据集成和组织方式等方面的多种需求。

As a common used format of data representation for structured data, table has been widely applied in various information systems. The automated creation and processing technologies of table have become the key technique for most of the information systems. Nowadays, Web, together with the traditional databases and document managing systems, makes up of an enormous, heterogeneous and distributed data warehouse, coming with which the aim of processing the massive and heterogeneous information has tabled new proposals to the modeling and processing of table. However, the existing techniques on modeling of table have been less focused on various types of table and the integration of heterogeneous data source, and the structure of the current models seems a little simple. Aiming to these scarcities, this article analyses the requirements of table processing techniques in the design and implementation of various information system and proposes the table modeling method oriented to data binding, which can satisfy the requirements of the data level and the view level on data type, data integration and data organization.
