MODELING A HIERARCHICAL DATABASE WITH XML

2009    Yurekten, Ozguer; Bilge, Hasan Sakir

Electronic Warfare Integrated Reprogramming DataBase (EWIRDB) is the largest data source in the area of electronic warfare. The information in this data source is stored and managed as plain files. The structure of this data source has the following characteristics; dynamic data expandability, ability to store over 2400 parameters, ability to accommodate incomplete data, supporting hierarchically modeled structure. It is difficult to design hierarchical data structure using the relational or object oriented database system; therefore EWIRDB remains as a legacy system and its data is still stored in plain files. When this large structure is modeled using the relational or object oriented databases, the complexity of development increases and the out-coming product is hard to use. The goal of this study is to enable EWIRDB data source to be managed and used more effectively. As an alternative of relational and object oriented database, XML database, which has superior capability of managing hierarchical data structures, is used for better management of data.
