Tiny Data - What is that supposed to be? Imagine the following situations. A few months ago, you had a great idea and wrote it down in an electronic file. Suddenly you need your notes, but how do you find them? Because somehow they are not in the place you remember them to be. And your operating system doesn’t know about a thing called “note”. But you could still search your entire drive…

K4 is a new (as of 2018) cross-platform database application which allows it to manage all kinds of personal data K4 uses advanced database capabilities like procedural SQL to integrate data structures and business logic into database layer instead of creating a middleware solution that acts as an additional layer between data storage and user interface K4 uses a software package separate from the database called PM (written in Python 3) to harvest data and to structure it before writing it to the database as well as to extend abilities of the database to manipulate and analyze data K4 features a generic graphical user interface written in Object-Pascal that is responsible for searching, presenting and maintaining data K4 GUI aims to let the user do simple things in a simple way K4 promotes the idea of “Tiny Data” (as opposed to “Big Data”): Acquire as little data as necessary instead of as much as possible K4 currently runs on Linux and Windows with Firebird as database The term K4 or the K4-website are not related to other tools with similar names.

It’s done! After nearly 2 years we finished compiling the results collected with DSBENCH-marking several servers and desktops. Abstract To find means to qualify arbitrary computers regarding their capability to act as a database server we perform a large number of tests to understand which characteristics of a computer system influence the performance most. We qualify performance by measuring storage system throughput and by extensively testing the system with a self–developed TPC-B like performance benchmark program called DSBENCH.

Presentation at Chemnitzer Linux Tage 2016 event is done now. Please, feel free to download it (in German).

This is the last release of DSBENCH software. Although we gave an outlook at CLT-2016, no more development or extension is intended. Please, find installation and usage instructions included as INSTALL and MANUAL. Download-Links (Version 1.1.10): TAR-Archiv for Linux ZIP-Archiv for Windows

DSBENCH is a new (as of 2016) cross-platform, cross-database benchmark which assesses the capability of a computer to act as a server for relational database systems DSBENCH uses a “TPC-like” benchmark profile; its model is based on the technical parts of the TPC-B specification. DSBENCH is, however, NOT in any way certified by or related to the Transaction Processing Performance Council (TPC) and does not claim to produce results compatible with TPC-B.
