Course info: Evaluation
Up to 33 points from iterations (for completing assignments of the semestral project with the best effort
and clean code).
Up to 42 points for your team project (for creating a complex solution, dividing work, and collaborating
with others).
Up to 25 points for exams (the final ROPOT contains all the topics from the semester)
Up to 5.2 soft points for seminar ROPOTs - these apply after you gain at least 70 points from iterations,
team project, and exams to help you get a better grade.

Let's revise data modeling in ERD
Entity, Primary key, Foreign key, Relationship
Types of ERD: Conceptual, Logical, Physical models

Git: Setup
1. Install git (Depends on your OS)
Using a package manager:
apt install git # ubuntu/debian
brew install git # mac
winget install Git # windows package manager
Or you can use the Git website.
2. Setup keys
ssh-keygen -o -a 100 -t ed25519 -f ~/.ssh/id_muni -C "xuser@fi.muni.cz"
9
Git: Setup
3. Add public key to Gitlab
10
Git: Basics
Commit in Conventional commits
git config --global core.excludesFile "**/node_modules"
git config --global user.name xuser
git config --global user.email xuser@fi.muni.cz
git clone <url> # Clones the repository
git status # Show status of added, removed files
git checkout -b submit-00 # Switch to new branch
git commit -am "feat: added erd" # Commit all tracked files
git push origin submit-00 # Push commited to remote branch
Cheatsheet

Git: Gitflow
Starts from the main branch
Feature branches contain new features,
additions
Master/Main is stable (tagged)
Note: You'll most likely work in trunk based
development (it ignores the develop branch)
In-depth explanation
12
Git: Merge requests / Pull
request
MR/PR the way you check source code
changes into a main branch
Before pushing code, check common mistakes
CI is not your enemy
We require you to discuss changes
13
Workspace setup
IDE: Webstorm, VSCode, vim

Git: Gitkraken, Github desktop*

Extensions: PlantUML, GraphViz
Extensions will be announced in every seminar session (We use many in this course)

*Note: ignore if you like solving conficts on your own
14
Activity
1. Make group of 3-4 students
2. Model: Heureka domain on paper
Product, Category, Store, Product Price,
Product Photo
3. Logical model: focus on attributes, relations
4. Compare within groups in seminar
5. Code PlantUML (save it locally)
6. Git-Push to Gitlab (next slide)
15
Publishing the Heureka diagram as Submit 00
1. Fork the repository pb138/pb138-iterations-2023
2. Clone the repository
3. Create the branch submit-00
4. Save heureka.puml to branch submit-00
5. Invite your seminar tutor(s) to the project as developer(s)
6. Open merge request from submit-00 to main
7. Assign tutor as Assignee and Reviewer on Merge request
16
Publishing the Heureka diagram as Submit 00
And now wait... For the code review.
