This course is on Data Science (DS) and Process Modelling (PM), and is part of the (dutch) bachelor program "Informatica & Economie" of Leiden University.
It is also open to students from the minor Data Science, and sometimes lectures are together with students from the "Informatica" bachelor course Data Science.
Note that before 2019, the course was called Business Intelligence and Process Modelling (BIPM).
Compared to last year, the content of the course will change a little, but most importantly the name now better reflects the actual course contents.

News:
- Assignment 1 has been graded. In the next assignment, be sure to take into account the feedback given on this first assignment.
- Assignment 2 is available.

Werkcollege Feb 13/20, 2019

Today, we work on Assignment 1.

A crash-course on webdevelopment is available. In addition, tutorials can be found at W3 Schools (HTML, CSS, javascript, jQuery, Bootstrap). However, fluency in each of these languages is not per se required; some skeleton code is available, which may serve as a starting point.


About your webspace on the LIACS-ISSC webserver
Each user should have SSH-access to the liacs.leidenuniv.nl webserver when connecting from the workstations in computer rooms, or via WiFi 'wlan 3'. Your can create your own website by placing files, e.g., an index.html file, in the ~/public_html folder on this server. Your website is visible at http://liacs.leidenuniv.nl/~s....


Mounting your webspace
There is a possibility to conveniently mount the webserver's public_html folder on your own machine. From within the university this can be done by issuing the following commands:
mkdir public_html
sshfs s...@liacs.leidenuniv.nl:/home/s.../public_html ./public_html
The first command creates in your current working directory on your machine a folder public_html. This needs only to be done when this folder is not yet present. The second command mounts the remote folder ~/public_html on liacs.leidenuniv.nl in your local folder. Note that this second command should be run each after each logout or reboot.

Mounting your webspace from outside the university
ssh -f s...@sshgw.leidenuniv.nl -L 2222:liacs.leidenuniv.nl:22
sshfs localhost:2222:/home/s.../public_html ./public_html
With the first command you create a tunnel from localhost:2222 to liacs.leidenuniv.nl:22 (22 is the default port of SSH) via sshgw.leidenuniv.nl:22. After issuing this command all traffic to localhost:2222 is forward to the liacs.leidenuniv.nl server (which we use in the second command).

Course description (from your study guide 2018-2019 )

The data science aspects of this course deal with the ever-increasing need of organizations to analyze, visualize, mine and understand their own data. Topics include visualization, descriptive analytics and predictive analytics, but also more recent techniques such as network analytics. Each of these topics is addressed specifically in business-oriented and/or economical context, which is reflected in the course assignments and provided case studies. The process modelling aspect of this course addresses the fact that organizations must constantly optimize, update, and monitor the execution of their processes to stay competitive and efficient. These processes are developed on the basis of organizational targets and strategic goals, but of course the underlying IT landscape is also of influence on process design, development, implementation, and execution. During this course, data science and process modelling finally come together in the topic of process mining: a data-driven approach to understanding business process management.

The course was also given in 2015, 2016, 2017 and 2018.


The second part of this course heavily builds upon the book "Process Mining: Discovery, Conformance and Enhancement of Business Processes" by W. van der Aalst (2nd edition, Springer, 2016). As such, much of the materials in the lecture slides and exercises of this course originate from the book and accompanying courses by the book's author(s). Logically, all credits for these materials go the respective author(s).
