Abstract
. We should consider semistructured data of which have a weak schema information in networked information world. To manage such semistructured data efficiently, this paper introduces a data model for semistructured data and operations for schema construction. We transform semistructured data into structured one by introducing schema construction methodology, compared to the former studies which are fully dependent on schemaless manipulations. For schema construction, we defined operations for building IS-A/IS-PART-OF relationships, collecting data objects to build a primitive class, and merging two data instances or classes. 1 Introduction 1.1 Motivation In early stages of data processing such as inventory/account management systems, a centralized large database system was used as an information server. Through the database design (or real-world modeling) phase, DBA(Database Administrator) defines a well-structured schema. We perform data acquisition and creation after sche...
