Performance evaluation of database management systems
… query using a DBMS. We presented the ABLE buffer management algorithms for DBMS's. We give cost models for both relational DBMS's and network DBMS's. We also give some of the results of our experiments for testing the performance of the ABLE buffer management algorithm and the accuracy of the cost …

Learned scheduling for database management systems
Parallel database management systems need efficient job scheduling. Currently systems use simple heuristics ignoring the characteristics of database workloads. Therefore, we created an effective scheduler that uses machine learning techniques, such as reinforcement learning and neural networks, and …

Visual assessment and relational database management
… been included in the assessment and a relational database management program has been used in the storage of all collected data. As a result of this process, it was found that a new method, which borrows from past processes, addresses the needs of the land planner, and utilizes an interactive …

Autonomic Workload Management for Database Management Systems
In today’s database server environments, multiple types of workloads, such as on-line transaction processing, business intelligence and administrative utilities, can be present in a system simultaneously. Workloads may have different levels of business importance and distinct performance …

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 …

Multiprocessor architectures for supporting secure database management
… which is often embedded In the operating system, database management system, or both is difficult to change and verify. This dissertation presents a new system architecture that can possibly solve many of the problems of protection and security found in a conventional environment. This new system …

Query processing in heterogeneous distributed database management systems
… in support of heterogeneous distributed database management systems. Heterogeneous distributed database management systems view the integrated data through an uniform global schema. The query processing algorithm described here produces an inexpensive strategy for a query expressed over …

Handling the “Curation Crisis:” Database Management for Archaeological Collections
… in museums with few plans for their long-term management, care and preservation. While the existence of a “curation crisis” has been widely accepted in the United States since the 1970s, there is little agreement as to a solution that can be accomplished in a practical, affordable, and …

A relational database management systems approach to system design
… input variable values. An intelligent relational database management system is defined to solve the problem described. Table structures are defined to maintain the required data elements and algorithms are constructed to manipulate the data to provide the necessary information. The methodology is …

Exploring learned join algorithm selection in relational database management systems
… optimizers, crucial components of relational database management systems, are responsible for generating efficient query execution plans. Despite many advances in the database community over the last few decades, most popular relational database management systems today still use cost-based …

Configurable Online Multi-Tiered Storage in a Database Management System
… design and implementation for this in a database management system (DBMS) [1, 2], which has been difficult in the past due to two key constraints: the immutability of its columns and its lack of atomicity for sub-partition level operations. Without atomicity, there are no mechanisms in …

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 …
