In this paper we experiment with two major types of query parallelization techniques - intra and inter operator parallelism and their combinations. We evaluate these techniques applied to a query tree with a number of join operators in the multithrea

Various software features such as classes, methods, requirements, and tests often have similar functionality. This can lead to emergence of duplicates in their descriptive documentation. Uncontrolled duplicates created via copy/paste hinder the proce

Automatic discovery of various types of database dependencies (functional, inclusion, matching, and others) is a topic that has received a great deal of attention in the recent years. The problem is formulated as following: having an unexplored datas

Data compression is widely used in contemporary column-oriented DBMSes to lower space usage and to speed up query processing. Pioneering systems have introduced compression to tackle the disk bandwidth bottleneck by trading CPU processing power for i

Currently, text chatting is one of the primary means of communication. However, modern text chat still in general does not offer any navigation or even full-featured search, although the high volumes of messages demand it. In order to mitigate these

Automatic crash reporting systems have become a de-facto standard in software development. These systems monitor target software, and if a crash occurs they send details to a backend application. Later on, these reports are aggregated and used in the

Many contemporary software products have subsystems for automatic crash reporting. However, it is well-known that the same bug can produce slightly different reports. To manage this problem, reports are usually grouped, often manually by developers.

Software documentation contains a large amount of duplicate text, which is often comprised of near duplicates — repetitions of the same text with slight differences. They emerge due to numerous copy-pastes that have been slightly modified. Uncontro

PosDB is an engine of a disk-based column-store DBMS designed for processing OLAP queries in a shared nothing environment. It is written completely from scratch and aims to become a platform for studying the distributed query processing in column-sto

A window function is a generalization of the aggregation operation. Unlike aggregation, the cardinality of its output is always the same as the cardinality of input. That is, the semantics of this operator imply computing values for extra attributes
