Using database replication in integration of heterogeneous data sources
Sep 25, 2015 Proceedings of 7th International Scientific Congress – ITeO 2015 (Informational Technology for e-Education)
Integration of data from heterogeneous sources is process focused on overcoming the diversity of the source systems, especially in the context of the platform and data structures. Integration of faculty information systems is focused on creating a unique global access points that would provide an insight into different categories of importance. This paper presents the approach to faculty data integration into a single database at the University level whose purpose is real time reporting. We used database replication based tool Oracle GoldenGate for integrati-on of heterogeneous data sources.

Applieance of open source solution in person identification through handwriting
Jul 2012, InfoM, Volume 42
Research in the area of handwriting authentication is growing since the devices with touch screen and stylus move to mass production. This paper explores achievements in this area with a focus on signature authentication. An off-line signature verification system which has been modified so that is able to use files with images of signatures for training and verification is presented. The system was tested on the original signatures, random and trained forgeries to examine what percentage of errors is given in any case and the results were very good. The paper provides a complete system with an intuitive graphical interface designed to verify the signature, which is one of the few if not the only one with open source, and is therefore open to further improvement and adaptation for specific systems. The system uses Dynamic Time Warping algorithm in combination with ER2 . System could be used in many situations since the signature is the most commonly used way of verification. The advantage of off-line system is that it does not require any specific input device, so they are ideal for verification from home.
