My graduation work is a project called Państwa Miasta as a big base with words for specific categories.
Name Państwa Miasta is from the paper game, very popular in many youth. One player says one letter from alphabet. In example L and the rest of the playing players (having on their papers columns with names: cities, countries, flowers, cars..) is trying get one word per column starting with that letter.
My project is about android app where user will be able preview big list of categories. When he enters in any of them, he will see from A to Z words connected with that category.
I decided to make this project because I have created first version of panstwa miasta app before. It wasn’t so flexible to manage it from other place like php/server.
