Wireless Network Communication in the XML Metadata Storage of Wushu Historical Archives

The wireless communication network has a huge promotion effect on data processing. As an important standard for internet data transmission, XML markup language is currently widely used in the internet. The rapid development of XML has brought fresh blood to the research of database. This article is aimed at studying the application of wireless network communication in the storage of the XML metadata database of Wushu Historical Archives. One part uses data load-balancing algorithms and two-way path constraint algorithms to conduct research on the metadata storage of XML databases, such as document size, document loading, and document query. Combining wireless technology and comparing with SGML and HTML, it highlights the flexibility and importance of XML database. The other part analyzes the XML database of Wushu Historical Archives itself and uses questionnaire surveys combined with the experience of 30 users randomly checked to provide constructive suggestions for the construction of XML database, such as strengthening the operation page design, text, and graphics. The experimental results show that the time consumed by the XML database in the case of bidirectional path indexing is 0.37 s, and the time consumed in the case of unidirectional path indexing is 0.27 s. This data shows that the application of wireless network communication technology has played an important role in the easy update and flexibility of the XML database. The data load capacity presented by the two path indexes is inconsistent; the current experience of XML database mainly focuses on the copy of the database quantity.

INTEGRATING A HISTORICAL CORPUS, A WORD INDEX, AND A DATABASE OF OLD EAST SLAVIC VERNACULAR WRITING

The paper presents work on two databases of vernacular Old East Slavic writing, viz. the databases of birchbark letters and epigraphy. The task is to link the information of archaeological/historical and linguistic character, namely, the possibility of simultaneous expansion and updating of the database and of a linguistic corpus that enables grammatical and lexical search. The online database Old East Slavic birch bark letters and the section of the historical subcorpus of the Russian National corpus containing birch bark letters call for an integration. This includes, in particular, creating an online workstation for the morphological markup of texts linked to the database entries, the possibility of exporting XML-databases with morphological markup to include them in the RNC, the possibility of automatic generation of forward and backward word indices to the database on the basis of the marked corpus, mutual verification of previously compiled manually indices to the book by A. A. Zalizniak The Old Novgorod Dialect (a new updated edition of this book is being prepared) and markup of the corpus. Creation of a new database on the Old East Slavic epigraphy is designed to overcome the fragmented state of the publications and research in the field, combining the material accumulated by the scholars into a single electronic resource. From the point of view of programming, the architecture of the epigraphy database is analogous to the one of the birch bark database, which makes it possible to create an annotated corpus of the Old East Slavic epigraphy.

The integration of XML databases and content management systems in digital editions

We have identified four models for integrating digital edition content into eXist-db [eXist-db], which are, in increasing order of dependence on eXist-db itself: 1) using Apache [Apache] and PHP [PHP] to mediate between the user and eXist-db, so that eXist-db provides only XML database services, 2) a pure XQuery framework for building an eXist-db web application [Web applications], 3) the eXist-db HTML templating framework [HTML templating], and 4) TEI Publisher [TEI Publisher]. Our examination and comparison of these ways of conceptualizing and implementing the infrastructure for a digital edition reveals that each of them has advantages and disadvantages, primarily from the perspective of sustainability. These considerations apply to edition frameworks generally, and are therefore not specific to eXist-db, which has been used here as an example because of the number of editions that employ it and the variety of models it currently supports.

Scaling XML Using a Beowulf Cluster

We describe a series of experiments which test the performance and scalability of an XML records system deployed on a Beowulf cluster of open source XML databases. Using the open source cityEHR health records system as an example, we first ran experiments to determine the feasibility and optimal size of database instances running on Raspberry Pi and low-cost Intel computers. We describe the implementation of a Data Access Layer for create, read, query and delete operations, using XForms submissions, which encapsulates all database access. We then present the results of testing the scalability and performance of this implementation on clusters of one to sixteen physical database nodes. We conclude that Beowulf clustering provides an effective and cost-efficient mechanism for scaling XML records systems.
