The Transaction Processing Performance Council (TPC) is a non-profit corporation founded to define transaction processing and database benchmarks and to disseminate objective, verifiable performance data to the industry. Established in August 1988, the ...

Experimental evaluation and comparison of techniques, algorithms, approaches or complete systems is a crucial requirement to assess the practical impact of research results. The quality of published experimental results is usually limited due to several ...

Graph Database Management systems (GDBs) are gaining popularity. They are used to analyze huge graph datasets that are naturally appearing in many application areas to model interrelated data. The objective of this paper is to raise a new topic of ...

In many fields of research and business data sizes are breaking the petabyte barrier. This imposes new problems and research possibilities for the database community. Usually, data of this size is stored in large clusters or clouds. Although clouds have ...

Transactional systems are the core of the information systems of most organizations. Although there is general acknowledgement that failures in these systems often entail significant impact both on the proceeds and reputation of companies, the ...

The value of a benchmark metric is directly related to how relevant it is to the consumer.

The inclusion of a price/performance metric and an availability date metric in TPC benchmarks has provided added value to consumers since the first TPC benchmark ...

In this paper, I survey briefly some of the recent and emerging trends in hardware and software features which impact high performance transaction processing and data analytics applications. These features include multicore processor chips, ultra large ...

As we approach the ten-year anniversary of the first working draft of the XQuery language, one finds XML storage and query support in a number of commercial database systems. For many XML use cases, database vendors now recommend storing and indexing ...

Intel co-founder Gordon E. Moore postulated in his famous 1965 paper that the number of components in integrated circuits had doubled every year from their invention in 1958 until 1965, and then predicted that the trend would continue for at least ten ...

For two decades, TPC benchmarks have been the gold standards for evaluating the performance of database servers. An area that TPC benchmarks had not addressed until now was virtualization. Virtualization is now a major technology in use in data centers, ...

TPC-Energy specification augments the existing TPC Benchmarks with Energy Metrics. The TPC-Energy specification is designed to help hardware buyers identify energy efficient equipment that meets both their computational and budgetary requirements. In ...

When originally introduced, flash based solid state drives (SSD) exhibited a very high random read throughput with low sub-millisecond latencies. However, in addition to their steep prices, SSDs suffered from slow write rates and reliability concerns ...

Ideally, realizing the best physical design for the current and all subsequent workloads would impact neither performance nor storage usage. In reality, workloads and datasets can change dramatically over time and index creation impacts the performance ...

With the emergence of XML as a standard for representing business data, new decision support applications are being developed. These XML data warehouses aim at supporting On-Line Analytical Processing (OLAP) operations that manipulate irregular XML ...

The TPC-H benchmark proved to be successful in the decision support area. Many commercial database vendors and their related hardware vendors used these benchmarks to show the superiority and competitive edge of their products. However, over time, the ...

Event Processing (EP) systems are being progressively used in business critical applications in domains such as algorithmic trading, supply chain management, production monitoring, or fraud detection. To deal with high throughput and low response time ...
