“…The considerations in the paper are based on the DAFO (Data Access based on Faceted queries over Ontologies), that was implemented on the top of a commercial relational database engine and ensures high efficiency of query answering. Some details of the implementation as well as the high efficiency of query answering are reported in our previous work [55,56,58].…”

The success of the use of ontology-based systems depends on efficient and user-friendly methods of formulating queries against the ontology. We propose a method to query a class of ontologies, called facet ontologies (fac-ontologies), using a faceted human-oriented approach. A fac-ontology has two important features: (a) a hierarchical view of it can be defined as a nested facet over this ontology and the view can be used as a faceted interface to create queries and to explore the ontology; (b) the ontology can be converted into an ontological database, the ABox of which is stored in a database, and the faceted queries are evaluated against this database. We show that the proposed faceted interface makes it possible to formulate queries that are semantically equivalent to $${\mathcal {SROIQ}}^{Fac}$$ SROIQ Fac , a limited version of the $${\mathcal {SROIQ}}$$ SROIQ description logic. The TBox of a fac-ontology is divided into a set of rules defining intensional predicates and a set of constraint rules to be satisfied by the database. We identify a class of so-called reflexive weak cycles in a set of constraint rules and propose a method to deal with them in the chase procedure. The considerations are illustrated with solutions implemented in the DAFO system (data access based on faceted queries over ontologies).

“…The performance of DAFO was evaluated on the basis of bibliographic datasets containing data on authors, papers, proceedings, and conferences [56]. The basic dataset was prepared by extracting data from DBLP 1 resources (from XML, HTML, and BibTex files), and enriched with data extracted from personal and conference home pages.…”

“…The hierarchy consists of tuples (N, E, <, T, V), with N being the name of the dimension, E as the set containing the attribute, and < as a partial sequence relationship defined in E. Therefore, ∀x, y ∈ E, x < y means that x is grouped into T according to the value of the hierarchical level (x < T, ∀x E), and V is the lower value, denoted as V < x, ∀x E. Another important attribute, known as size, represents the variable being analyzed. The steps are entirely dependent on and functionally linked to the attributes [31]. The development of physical data investigation models adapted to digital data relies on existing theories for physical crime investigations, among other factors [32].…”

The use of structured query formulation languages is a method for gaining access to data in information management systems. Writing structured queries is a powerful method of data retrieval, and end users can generate complex database queries by becoming proficient in a particular query language. Digitization of database information systems, history and endowment, and technology conservation are some examples of database conservation techniques in the process of displaying data that require optimal query techniques. Historical and endowment properties comply with a certain set of laws governing waqf recipients, which sets them apart from heritage and cultural assets. Trusted property typically comprises real estate, valuables, or both and has an infinite preservation term so long as it may still be put to use. A solid information technology infrastructure is essential for ensuring comprehensive data security. Given the availability of knowledge and the quick development of information technology, ensuring its sustainability is a challenge. This research is aimed at preserving historical and waqf databases based on the case study of the Kingdom of Sumedang Larang (KSL), Indonesia, through examination of the database, synchronization of digital data with physical data, as well as looking at its relationship with organizations and management. The proposed method, namely the Design and Analysis of Database Query Model for Preservation Information System (DAQMP), creates a recurring query model from the original tabular data placed in the next table as a special table check for data specifications containing important data. The results must be accurately aligned between digital and physical records regularly to serve as a record of any changes and as evidence to determine whether data has been corrupted, altered, or lost.
