Abstract The problem of transferring data from a database one type to another is relevant today due the increase in volumes and complexity tasks solved various fields human activity. existing databases are less satisfying needs users. New types appear that more suitable for solving large-scale problems. This article proposes an algorithm optimizing document structure based on metadata about dis...

NoSQL databases are an important component of Big Data for storing and retrieving large volumes of data. Traditional Relational Database Management Systems (RDBMS) use the ACID theorem for data consistency, whereas NoSQL Databases use a non-transactional approach called BASE. RDBMS scale vertically and NoSQL Databases can scale both horizontally (sharding) and vertically. Four types of NoSQL da...

Associating documents to relevant categories is critical for effective document retrieval. Here, we compare the well-known k-Nearest Neighborhood (kNN) algorithm, the centroid-based classifier and the Highest Average Similarity over Retrieved Documents (HASRD) algorithm, for effective document categorization. We use various measures such as the micro and macro F1 values to evaluate their perfor...

The trend of Cloud databases is leaning towards Not only SQL (NoSQL) databases as they provide better support for scalable storage and quick retrieval of exponentially voluminous data. One of the more prominent types of NoSQL databases is document-based storage, which is being increasingly used in the dynamic Cloud paradigm. However, there are inherent security issues in Cloud, including remote...

This paper reviews existing systems and describes a design of RDF database system that uses NoSQL database to store the data which aims to enhance performance of the Semantic Web applications. RDF data is a standard of data in the form of Subject-Predicate-Object called Triples and stored in database called Triple Store. Typically RDF database system uses SPARQL query language to query the RDF ...

Systems designed for efficient retrieval of conventional data can be very inefficient at retrieving documents. Documents have more complex structure than conventional data, and the kinds of queries made to document databases are unlike those made to conventional databases. This paper discusses how document storage and retrieval can be effectively supported in a nested relational database system...

In temporal document databases and temporal XML databases, temporal text-containment queries are a potential performance bottleneck. In this paper we describe how to manage documents and index structures in such databases in way that makes temporal text-containment querying feasible. We describe and discuss different index structures that can improve such queries. Three of the alternatives have...
