6 Overview lecture is completely new from scratch first itera)on no prior syllabus available depending on the advancements in the lecture single topics could be added or dropped the sequence of topics might be shuffled hybrid nature: presenta)on of exis)ng resources are blended with back- and front- end technology

7 Exercises Exercises help to convert knowledge into a skill prac)cal applica)on of topics covered in the lecture ac)ve explora)on of bioinforma)cs resources implemen)ng various parts of bioinforma)cs resource

8 Meaning What does resource actually means? a Google query about Bioinforma)cs Resource yields about 20 Mio hits falls roughly into three categories: - databases - tools - service centers

9 Working on a Defini)on a collec)on of informa)on which is useful to do research in the area of life sciences/ computa)onal biology contains the informa)on itself provides appropriate interfaces to access the informa)on may provide tools for interac)ve data analysis
