Towards a Cryptographically Verifiable Database Management System
Database-as-a-Service (DBaaS), like Amazon Web Service Redshift and Microsoft Azure SQL DB, is becoming increasingly popular. These services provide high performance and on-demand elasticity without heavy maintenance costs. However, as with all online applications, DBaaS is prone to malicious …

Configurable Online Multi-Tiered Storage in a Database Management System
… One approach to this problem is a tiered storage system, where new data is allocated to faster storage tiers and older data is pushed to lower tiers with slower retrieval time. This thesis presents a fully online and configurable design and implementation for this in a database management system …

Representing and querying regression models in a relational database management system
… declaratively and manipulated like traditional database relations. The key contributions of FunctionDB are a compact, algebraic representation for regression models as piecewise functions, and an algebraic query processor that executes declarative queries directly on this representation as …

Data mining and database systems: integrating conceptual clustering with a relational database management system.
… use of larger data sets that are often stored in database management systems (DBMSs). Many clustering algorithms require data to be extracted from the DBMS and reformatted for input to the algorithm. This thesis presents an approach that integrates conceptual clustering with a DBMS. The presented …

Towards Storing 3D Model Graphs in Relational Databases
… data reinforces the need for adequate graph data management. While several graph database engines have 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 …

Column Store Database - A New Approach to GIS Application
<p>Geographic Information Systems (GIS) were designed to model the world. However, with the growth of data and increasing sophistication of analy- sis and processing techniques, the traditional methods of performing GIS processing on desktops are insucient. This thesis addresses this issue by …

Towards trusted and efficient temporal relational databases
This research is to 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 …

Virtual time synchronization in distributed database systems
Distributed systems synchronized by Virtual Time have been topics of recent interest. Virtual Time follows an optimistic philosophy relying on rollback for synchronization instead of abortion or blocKing Although many applications have been suggested as candidates for Virtual Time, few were …

An Experiment Management Component for the WBCSim Problem Solving Environment
… computing environment WBCSim and its experiment management component. WBCSim is a web-based simulation system used to increase the productivity of wood scientists conducting research on wood-based composite and material manufacturing processes. This experiment management component integrates a …

Re-engineering a B-tree implementation using design patterns
… process. The evolution of a B-tree indexing system, which is a component in a database management system, is presented to illustrate how design patterns clarify the design and make it more understandable. This re-engineering is a necessary step towards a reusable design and implementation for …

An Integrated Life-Cycle Information Framework for Construction Project Management
… ICIM-S (Integrated Construction Information Management System) was developed by using an object-oriented programming language (OOP) and database management system (OODBMS). ICIM-S was implemented with data from two case studies. Through the implementation of ICIM-S, ICIM demonstrates the …

Viaduct : an interactive, very-high-level data manipulation language for a microcomputer-based database system.
… very-high-level data manipulation language for a database system is one in which the user specifies in non-procedural terms the operations that are to be performed on the data stored in the database; the actual method by which the operations are executed does not concern the user. VIADUCT provides …

Scheduling in a Database-Based Distributed Operating System
Current operating systems date from over 40 years ago and were designed for very different computing requirements, making them ill-equipped to handle serverless workloads as well as modern challenges in scalability, heterogeneity, availability, and security. Hence, we propose a radically new …

Performance of Concurrency Control Methods in Distributed Database Management Systems (Timestamp Ordering, Two-Phase Locking, Optimistic Scheme, Restart, Transaction Blocking)
… the performances of those CCMs in distributed database management system (DDBMS) were simulated with some care to get statistically significant results. The performances of the CCMs were then compared with respect to several measures. This study systematically investigated effects of major …

Transaction reconstruction
Databases are distributed and replicated to increase the efficiency and resiliency of a database management system; unfortunately, mechanisms to improve resiliency can have a substantial negative impact on the overall efficiency of the system. Current approaches to resiliency extend transaction …

The impact of network characteristics on the selection of a deadlock detection algorithm for distributed databases
… the problem of deadlock detection in distributed databases, resulting in the publication of numerous algorithms to accomplish this function. The algorithms published to date differ greatly in many respects: timing, location, information collection, and basic approach. The emphasis of this research …
