Graph analytics on relational databases
… recent years. Conventionally, data is stored in relational databases that have been refined over decades, resulting in highly optimized data processing engines. However, the awkwardness of expressing iterative queries in SQL makes the relational query-processing model inadequate for graph …

DataSpread: scaling spreadsheets using relational databases
… DataSpread, a system that holistically unifies databases and spreadsheets with a goal to work with massive spreadsheets: DataSpread retains all of the advantages of spreadsheets, including ease of use, ad-hoc analysis and visualization capabilities, and a schema-free nature, while also adding …

Towards trusted and efficient temporal relational databases
… develop a blockchain based database based on a relational database management system (RDBMS). The database guarantees authenticity of the stored records using immutable and verifiable signatures. The database supports query evaluation over the entire timeline of the transaction log. To support …

Towards Storing 3D Model Graphs in Relational Databases
… been developed, the storage of graph data in a relational database management system, and therefore the seamless integration into existing information systems remains an open challenge. Motivated by the use case to integrate Building Information Modeling (BIM) data into the MonArch system, we …

Differentially Private Synthetic Data Generation for Relational Databases
… existing DP mechanisms to generate synthetic relational databases. The algorithm iteratively refines the relationship between individual synthetic tables to minimize their approximation errors in terms of low-order marginal distributions while maintaining referential integrity; consequently …

Easing access to relational databases : investigating access to relational databases in the context of both novice and would-be expert users
Relational databases are commonplace in a wide variety of applications and are used by a broad range of users with varying levels of technical understanding. Extracting information from relational databases can be difficult; novice users should be able to do so without any understanding of the …

Keyword search in graphs, relational databases and social networks
… information from structured data (e.g., relational databases and XML documents). It offers an alternative way to query languages (e.g., SQL) to explore databases, which is effective for lay users who may not be familiar with the database schema or the query language. This dissertation …

The Synthetic Data Vault : generative modeling for relational databases
… (SDV), a system that builds generative models of relational databases. We are able to sample from the model and create synthetic data, hence the name SDV. When implementing the SDV, we developed an algorithm that computes statistics at the intersection of related database tables. We then use a …

Towards a concurrent implementation of keyword search over relational databases.
Vast amounts of data are stored in relational databases. Traditionally, querying this data required a deep understanding of the underlying schema in addition to knowledge of a query language such as structured query language (SQL). We present a framework for the automatic, lossless transformation …

Mapping relational databases to semantic web using domain-specific knowledge
… inferencing about the information ("knowledge"). Relational models are limited to the interpretation of purely relational data and do not provide sufficiently rich means for interpreting the knowledge associated with the use of the data. Relational languages lack the expressiveness to represent …

Prime Number-Based Hierarchical Data Labeling Scheme for Relational Databases
… a specific kind of hierarchy. Object oriented databases may also be used to model hierarchical data. Relational database systems, on the other hand, add an additional benefit of mature mathematical theory, reliable implementations, superior functionality and scalability. Relational databases …

Effective semantic-based keyword search over relational databases for knowledge discovery
… engines. The current amount of text data in relational databases is massive and is growing fast. This increases the importance and need for non-technical users to be able to search for such information using simple keyword search just as how they would search for text documents on the web. …

An Abstract Algebraic Theory of L-Fuzzy Relations for Relational Databases
Classical relational databases lack proper ways to manage certain real-world situations including imprecise or uncertain data. Fuzzy databases overcome this limitation by allowing each entry in the table to be a fuzzy set where each element of the corresponding domain is assigned a membership …

BlendDB : blending table layouts to support efficient browsing of relational databases
The physical implementation of most relational databases follows their logical description, where each relation is stored in its own file or collection of files on disk. Such an implementation is good for queries that filter or aggregate large portions of a single table, and provides reasonable …

On the use of NAND flash memory in high-performance relational databases
High-density NAND flash storage has become relatively inexpensive due to the popularity of various consumer electronics. Recently, several manufacturers have released IDE-compatible NAND flash-based drives in sizes up to 64 GB at reasonable (sub-$1000) prices. Because flash is significantly more …

Objektinių ir reliacinių duomenų bazių taikymas objektiškai orientuoto programavimo kontekste /
This MA paper aims at object and relational databases application comparison in the context of object oriented programming. Joint usage of databases and object oriented programming raises two problems relevant today. First problem is impedance mismatch of relational databases and object oriented …
