....repository of XML documents can be found. The data that is available is too small to extract meaningful statistics. Most of the XML documents in the data centric classes are currently relational that may be translated into XML for communication. Therefore, the schema of the TPC W benchmark (see [27] for details) is used and is mapped to XML. TPC W is a mature, and industry accepted, benchmark for Web based ecommerce systems that captures the database characteristics of the DC classes of documents. Elements and attributes are two basic entities in XML documents, and respectively there are ....

....of documents. Appendix D.2 and E.2 show detailed schema and DTD information. 4.3.3 DC MD As indicated earlier, due to the nature of data centric documents, it s very di#cult to get real XML documents, since most of e commerce and transactional data are still stored in relational databases. TPC W [27] benchmark schema proves a good starting point for modelling this type of data. Therefore, TPC W schema is used as the basis of these two classes. There are eight basic individual tables (relations) in the TPC W database. ORDERS purchase order information such as order date, price and status; ....

Here, we introduce places with full application functionality and employ synthetic workloads complying to the TPC W specification [27]. In the following sections, we introduce a suite of micro ben marks and micro kernels that we use to evaluate the performance of mobile agent middleware quantitatively. In earlier work we have examined micro applications that involved the use of mobile agents to provide database access over the ....

....select single, for all entries,orselect up to n rows) A representative of each class of statements was chosen as the basis for our analysis. The data was extracted from an actual productive SAP R 3 system rather than relying on artificially generated data, as, e.g. the TPC C benchmark does [25]. We analyzed a variety of partitioning schemes (data with and without index partitioning) and compared the performance with a conventional non partitioned database configuration. Our results show that also in the context of centralized shared everything database systems horizontal partitioning ....

The data for our databases was taken from the TPC D [TPC99] benchmark suite of scale factor 1.0. To suit our limited benchmark environment, we converted the 10000 suppliers round robin by SUPPKEY to only 26 suppliers, each being allocated to an individual host. The PARTSUPP table represented the market place and the PART table was partitioned ....

....stream, the referee learns the respective values from each stream. Thus we can estimate aggregate functions over the values associated with distinct labels in one or more data streams, e.g. the variance in request sizes averaged over all distinct destinations. As epitomized by the TPC benchmarks [25], which are the primary industry benchmarks for large scale query processing, many queries and reports seek aggregates of values over the distinct labels or groups of a data set. Next, we consider the previously studied streams model in which there is only one party, who observes both streams, ....

Successful benchmark suites strongly influence academic computer papers and ultimately vendor designs. Influential ones include the 1980 s Livermore Loops and the 69 1990 s SPEC [10] and TPC [11]. Furthermore, the influence of SPEC and TPC has been maintained for a decade, because they are updated every 3 years or so. NSA has informed me of an unclassified NSA benchmark suite. These benchmarks are already provided to vendors to enable them to see how their machine might work for the NSA. ....

....runs on a Pentium II 450 MHz processor with 256 MB RAM. 4.1. Compression plans optimized for network transmission vs. WinZip We need to choose a set of queries that are realistic and have large result size (needing compression) We accomplish this by adapting queries from the TPC D benchmark [TPC95]. We justify this choice because: Queries in the TPC D benchmark are characteristic of a wide range of decision support applications. The data in the TPC D benchmark contains data with various data types and various redundancies. Most queries include grouping and aggregation, making their ....

....data accesses, different percentages of write access, and the 80 20 rule. This rule assumes that 80 of all data references access a hot spot area covering 20 of the entire database [Bhi88, CFLS91, DY92] We used a different approach. We adapted our transaction model to the OLTP TPC C benchmark [Tra95] because CHAPTER 3. SIMULATION MODEL 36 we think that this benchmark models the workload of real world applications in a much better way than the simple 80 20 rule. Furthermore, the TPC C benchmark is the industry accepted standard for high performance database systems [Ide96] We first give ....

....The database tables Although the TPC C requires scaling of the database size relative to the throughput we sticked to a fixed database size of 400 warehouses for all our test runs to be able to compare the different approaches on a common basis. According to the storage requirements described in [Tra95] each warehouse needs 120 MByte storage capacity for a 12 hour run of the application. Therefore, our setting results in a database size of 48 GBytes. This size has been chosen so that one processor and its database buffer are too small, will be saturated, and become the bottleneck of the ....

....Impact of Rescheduling In this section we describe a set of experiments to study the potential impact of scrambling rescheduling for a more application oriented query than the uniform and non uniform cases shown so far. The experiments use a simplification of the query Q2 of the TPC D benchmark [Tra95] We chose this query because it is relatively simple, yet processes a five way join. The cardinalities of the relations involved in this query are as follows: PART: 200,00 tuples of 164 bytes, SUPPLIER (S) 10,000 tuples of 197 bytes, PARTSUPP (PS) 800,000 tuples of 219 bytes, NATION (N) 25 ....

In addition, a whole new industry, data warehouses, has appeared with products that materialize (i.e. pre compute) query results and cache the results of queries. Furthermore, the TPC D benchmark [TPC95] has been proposed in order to evaluate the performance of a database product for decision support queries. In this work, we present a new class of algorithms that can be used to speed up the execution of decision support queries that involve one or more joins and a group by operation. The idea ....

Our test database is characterized in Table 1. It consists of a Customer, Order, and Lineitem table with the usual TPC D style schema [TPC95] The cardinalities of the tables are set according to the TPC D specifications at a scaling factor of five. In some experiments, however, we varied the cardinality of the Order table in order to demonstrate the scalability of the approaches along that dimension. We generated random tuples using ....

....[BHG87] 15 Comparison of PA and KVL IM We intend in this subsection to compare PA to KVL IM locking in terms of CPU efficiency. To start with, we wish to estimate X CPU , the CPU overhead for KVL IM index locking per unit of execution of the given workload (such a unit of execution in TPC R [TPCR], for example, would be the sequence of queries Q1 through Q22 with update refresh functions RF1 and RF2 intermixed) We claim that X CPU can be approximated by the following formula: X CPU = K N p (X Lp R Lp ) K N u (X Lu R Lu ) Here, K is the CPU time needed to take a KVL IM lock or Row ....
