Information system for management of biological samples

Diplomska naloga se ukvarja s problematiko shranjevanja, obdelavo in analizo večjih količin podatkov, ki so rezultat delovnega procesa raziskovalnih laboratorijev. Razvit in implementiran je bil podporni informacijski sistem, ki naslavlja omenjeno problematiko. Tiskano obliko shranjevanja podatkov, ki je bila v ciljnem laboratoriju uporabljena prej, je z vpeljano rešitvijo nadomestila centralizirana podatkovna baza. Interakcija uporabnika s podatkovno bazo poteka preko grafičnega spletnega vmesnika, ki omogoča shranjevanje in prikazovanje podatkov. Informacijski sistem poleg elektronskega evidentiranja vzorcev in shranjevanja podatkov o vzorcih vpelje tudi standardizirano označevanje vzorcev s hitro berljivimi kodami QR, ki predstavljajo unikatno označbo vzorca. Vpelje tudi strukturo fizičnih označb na samem vzorcu, ki mora poleg optične kode vsebovati tudi podatke, nujne za hitro razpoznavanje vzorca. V delu se seznanimo z uporabljenimi tehnologijami in metodologijami. Pregledamo celoten postopek implementacije in razvoja posameznih delov sistema. Na koncu opišemo, in sicer korake procesa, v katerega je vključen posamezen vzorec v ciljnem laboratoriju. Od označevanja in evidentiranja izvornega vzorca do zaključka eksperimenta z izdelavo poročila o analizi pridobljenih podatkov za posamezen vzorec.The thesis addresses the problematic of handling, storage and analysis of large quantities of data, which are the product of the working process in research laboratories. A supporting information system that addresses the aforementioned issue was developed and implemented. Printed data records were replaced with centralized database environment. User interaction with the database was realized via a graphic user interface, which provides input and display of data. In addition to the electronic recording of samples and storage of sample data, information system also introduces standardized markings of samples with easily readable QR codes, which provide unique sample identifiers. The system also introduces the structure of physical labels on the sample itself, which, in addition to optical code, must also contain the data necessary for rapid recognition of samples. We get acquainted with the technologies and methodologies used. We review the entire process of development and implementation of individual components of the system. Finally, we describe the steps of the process in which samples are included, from labeling and recording the initial sample, to the conclusion of the experiment with the report of the analysis of obtained data for each sample
