Abstract [en]

The Intelligent Parameter Utilization Tool (InPUT) is a format and API for thecross-language description of experiments, which makes it possible to defineexperiments and their contexts at an abstract level in the form of XML- andarchive-based descriptors. By using experimental descriptors, programs can bereconfigured without having to be recoded and recompiled and the experimentalresults of third-parties can be reproduced independently of the programminglanguage and algorithm implementation. Previously, InPUT has supported theexport and import of experimental descriptors to/from XML documents, archivefiles and LaTex tables. The overall aim of this project was to develop an SQLdatabase design that allows for the export, import, querying, updating anddeletion of experimental descriptors, implementing the design as an extensionof the Java implementation of InPUT (InPUTj) and to verify the generalapplicability of the created implementation by modeling real-world use cases.The use cases covered everything from simple database transactions involvingsimple descriptors to complex database transactions involving complexdescriptors. In addition, it was investigated whether queries and updates ofdescriptors are executed more rapidly if the descriptors are stored in databasesin accordance with the created SQL schema and the queries and updates arehandled by the DBMS PostgreSQL or, if the descriptors are stored directly infiles and the queries and updates are handled by the default XML-processingengine of InPUTj (JDOM). The results of the test case indicate that the formerusually allows for a faster execution of queries while the latter usually allowsfor a faster execution of updates. Using database-stored descriptors instead offile-based descriptors offers many advantages, such as making it significantlyeasier and less costly to manage, analyze and exchange large amounts of experi-mental data. However, database-stored descriptors complement file-baseddescriptors rather than replace them. The goals of the project were achieved,and the different types of database transactions involving descriptors can nowbe handled via a simple API provided by a Java facade class.
