Sequence-Oriented DBMS Fuzzing

IEEE International Conference on Data Engineering, 2023
The SQL specification consists of hundreds of statement types, which leads to difficulties in DBMS fuzzing: state-of-the-art works generally reuse the statements of predefined types; the limited types cannot cover the full input space and test the ...

Cardinality Estimation in DBMS: A Comprehensive Benchmark Evaluation

Proceedings of the VLDB Endowment, 2021
Cardinality estimation (CardEst) plays a significant role in generating high-quality query plans for a query optimizer in DBMS. In the last decade, an increasing number of advanced CardEst methods (especially ML-based) have been proposed with ...

LlamaTune: Sample-Efficient DBMS Configuration Tuning

Proceedings of the VLDB Endowment, 2022
Tuning a database system to achieve optimal performance on a given workload is a long-standing problem in the database community. A number of recent works have leveraged ML-based approaches to guide the sampling of large parameter spaces (hundreds of ...

GaccO - A GPU-accelerated OLTP DBMS

SIGMOD Conference, 2022
In this paper, we present GaccO - a main memory DBMS for GPU-accelerated OLTP. For executing OLTP workloads, GaccO implements a novel scheme that splits the execution across the CPU and the GPU.

FlexPushdownDB: Hybrid Pushdown and Caching in a Cloud DBMS

Proceedings of the VLDB Endowment, 2021
Modern cloud databases adopt a storage-disaggregation architecture that separates the management of computation and storage. A major bottleneck in such an architecture is the network connecting the computation and storage layers.

Re-assessment of the depth to the base of magnetic sources (DBMS) in Australia from aeromagnetic data using the defractal method

, 2021
Australia and North America are the only two continent-wide regions, currently, with the complete wavelength spectrum of magnetic anomalies that can address the much-debated issue of the existence and understanding the magnetic state of the upper ...

Mozi: Discovering DBMS Bugs via Configuration-Based Equivalent Transformation

International Conference on Software Engineering
Testing database management systems (DBMSs) is a complex task. Traditional approaches, such as metamorphic testing, need a precise comprehension of the SQL specification to create diverse inputs with equivalent semantics.

Sedar: Obtaining High-Quality Seeds for DBMS Fuzzing via Cross-DBMS SQL Transfer

International Conference on Software Engineering
Effective DBMS fuzzing relies on high-quality initial seeds, which serve as the starting point for mutation. These initial seeds should incorporate various DBMS features to explore the state space thoroughly.

C-Store: A Column-oriented DBMS

Very Large Data Bases Conference, 2005
This paper presents the design of a read-optimized relational DBMS that contrasts sharply with most current systems, which are write-optimized. Among the many differences in its design are: storage of data by column rather than by row, careful coding and

ChronosDB: Distributed, File Based, Geospatial Array DBMS

Proceedings of the VLDB Endowment, 2018
An array DBMS streamlines large N -d array management. A large portion of such arrays originates from the geospatial domain. The arrays often natively come as raster files while standalone command line tools are one of the most popular ways for ...
