+# M141 LB 3 T.B
+
+# Platform
+To avoid confusion and potential hickups in the future I've mentioned what system this was done on incase it does not work on other ones.
+
+- OS : MacOS Sonoma 14.4.1
+- Shell : ZSH 5.9 Apple Darwin
+- MariaDB : 11.4.2-MariaDB Homebrew
+
+Additional installated 
+
+# Note
+All steps done in folder : work_dir
+ 
+# LB3
+
+## Importing the files
+Note : Make sure that you have Adminstrative Permissions for the MariaDB server
+
+### Importing the SQL file
+
+1. Geting the SQL file that is to be imported
+```bash
+curl -O https://gitlab.com/ch-tbz-it/Stud/m141/m141/-/raw/main/LB3-Praxisarbeit/backpacker_ddl_lb3.sql
+```
+2. Log into MariaDB
+```bash
+mysql #my user is set to be an administrator for mariadb
+```
+3. Make new Databse
+```sql
+CREATE DATABASE IF NOT EXISTs backpacker_lb3;
+```
+4. MariaDB Verlassen
+```sql
+exit
+```
+5. Datenbank Importieren
+```bash
+mysql backpacker_lb3 < backpacker_ddl_lb3.sql
+```
+
+### Importing the CSV file
+
+1. Getting the CSV files to be imported, unzipping it, delete the MacOS metadata folder and the nolonger neeeded zip file then "rename" the folder to csv.
+```bash
+curl -O https://gitlab.com/ch-tbz-it/Stud/m141/m141/-/raw/main/LB3-Praxisarbeit/backpacker_lb3.csv.zip; unzip backpacker_lb3.csv.zip; rm -rf __MACOSX; rm backpacker_lb3.csv.zip; mv backpacker_lb3.csv csv
+```
+
+2. Get the current working directory and copy it to the clipboard
+```bash
+pwd
+```
+
+3. Log into MariaDB
+```bash
+mysql
+```
+4. Change to backpacker database
+```sql
+use backpacker_lb3
+```
+
+5. Import the CSV files
+Note : I've already looked at the csv's and the tables existing hence why I've added rules to the default import to avoid any issues from accuring
+Keep in mind this command has to be run for each table/csv!
+```sql
+load data local infile '/Users/crt/Documents/TBZ/M141/m141-lb3/work_dir/csv/backpacker_lb3_table_tbl_positionen.csv' into table tbl_ppositionen fields terminated by ',' enclosed by '"' lines terminated by '\n' ignore 1 rows;
+```
+
+## Making changes to the database
+From now on it us assumed that were already logged in to MariaDB and have selected the correct database
+
+### Hashing the Password of the users
+```sql
+update tbl_benutzer set Password = MD5(Password);
+```
+
+### Changing table names
+```sql
+rename table tbl_positionen to tbl_position;
+rename table tbl_personen to tbl_person;
+```
+
+### Changing Attributes
+```sql
+alter table tbl_buchung change column Buchungs_ID Buchung_ID INT;
+alter table tbl_buchung change column Personen_FS Person_FS INT;
+alter table tbl_person change column Personen_ID Person_ID INT;
+alter table tbl_position change column Positions_ID Position_ID INT;
+alter table tbl_position change column Buchungs_FS Buchung_FS INT;
+
+```
+
+### Adding Indexes
+```sql
+alter table tbl_buchung add index idx_Person_FS (Person_FS);
+alter table tbl_buchung add index idx_Land_FS (Land_FS);
+alter table tbl_position add index idx_Buchung_FS (Buchung_FS);
+alter table tbl_position add index idx_Benutzer_FS (Benutzer_FS);
+alter table tbl_position add index idx_Leistung_FS (Leistung_FS);
+
+```
+
+### Adding Indexing to frequently used Columns
+```sql
+alter table tbl_benutzer add index idx_Benutzername (Benutzername);
+alter table tbl_benutzer add index idx_aktiv (aktiv);
+alter table tbl_buchung add index idx_Ankunft (Ankunft);
+alter table tbl_buchung add index idx_Abreise (Abreise);
+alter table tbl_person add index idx_Name (Name(20));
+alter table tbl_position add index idx_erfasst (erfasst);
+
+```
+
+### Linking foreign keys
+
+#### For tbl_buchung
+```sql
+alter table tbl_buchung add constraint fk_person_buchung foreign key (Person_FS) references tbl_person (Person_ID);
+alter table tbl_buchung add constraint fk_land_buchung foreign key (Land_FS) references tbl_land (Land_ID);
+
+```
+
+#### For tbl_position
+```sql
+alter table tbl_position add constraint fk_buchung_position foreign key (Buchung_FS) references tbl_buchung (Buchung_ID);
+alter table tbl_position add constraint fk_benutzer_position foreign key (Benutzer_FS) references tbl_benutzer (Benutzer_ID);
+alter table tbl_position add constraint fk_leistung_position foreign key (Leistung_FS) references tbl_leistung (LeistungID);
+```
+
+## Optimizing the Database
+```sql
+analyze table tbl_benutzer, tbl_buchung, tbl_land, tbl_leistung, tbl_person, tbl_position;
+optimize table tbl_benutzer, tbl_buchung, tbl_land, tbl_leistung, tbl_person, tbl_position;
+
+```
+
+## Making users and managing permissions
+
+### Create users
+```sql
+create user if not exists 'benutzer'@'localhost' identified by 'Example_User_Password123';
+create user if not exists 'management'@'localhost' identified by 'Example_Mgmt_Password123';
+```
+
+### Set "benutzer" Priviliges
+```sql
+grant select, update on tbl_person to 'benutzer'@'localhost';
+grant select, insert, update (Benutzer_ID, Benutzername, Vorname, Name, Benutzergruppe, erfasst, aktiv) 
+on tbl_benutzer to 'benutzer'@'localhost';
+grant select (deaktiviert) on tbl_benutzer to 'benutzer'@'localhost';
+grant select, insert, update, delete on tbl_buchung to 'benutzer'@'localhost';
+grant select, insert, update, delete on tbl_position to 'benutzer'@'localhost';
+grant select on tbl_land to 'benutzer'@'localhost';
+grant select on tbl_leistung to 'benutzer'@'localhost';
+```
+### Set "management" Priviliges
+```sql
+grant select on tbl_position to 'management'@'localhost';
+grant select on tbl_buchung to 'management'@'localhost';
+grant select, insert, update, delete on tbl_person to 'management'@'localhost';
+grant select, insert, update, delete on tbl_benutzer to 'management'@'localhost';
+grant select, insert, update, delete on tbl_land to 'management'@'localhost';
+grant select, insert, update, delete on tbl_leistung to 'management'@'localhost';
+```
+
+### Reload priviliges
+```sql
+flush privileges;
+```
+
