+# CountrySeedGenerator
+
+This folder contains the Python helper for generating `04-countries.sql` seed scripts for PostgreSQL and Microsoft SQL Server 
+(defined as Docker containers using docker-compose.yml)
+
+The commands below assume you are running them from inside the `CountrySeedGenerator` folder.
+
+Install dependencies:
+
+```powershell
+python -m pip install -r requirements.txt
+```
+
+Run the generator:
+
+```powershell
+python create_countries_sql.py postgres
+python create_countries_sql.py mssql
+```
+
+The script shows the default output path based on the selected target and asks you to confirm it before writing the file.

+# PeopleDataGenerator
+
+`PeopleDataGenerator` contains the .NET helper for generating person seed SQL for both PostgreSQL and Microsoft SQL Server.
+
+It is used as supporting material for the teaching examples in this repository and helps produce realistic multilingual seed data for the sports-events domain.
+
+The commands below assume you are running them from inside the `PeopleDataGenerator` folder.
+
+## What It Does
+
+- generates fake participant data with locale-specific names and transliterations
+- asks whether the target should be PostgreSQL or Microsoft SQL Server
+- writes SQL insert statements to the matching `init` folder
+
+By default, the people generator writes to:
+
+```text
+docker-definitions\postgres-eventsdb\init\06-people.sql
+docker-definitions\mssql-eventsdb\init\06-people.sql
+```
+
+## Prerequisites
+
+- .NET SDK 10.0
+
+## Running
+
+```powershell
+dotnet run --project PeopleDataGenerator.csproj
+```
+
+You can also pass the target as the first argument:
+
+```powershell
+dotnet run --project PeopleDataGenerator.csproj -- postgres
+dotnet run --project PeopleDataGenerator.csproj -- mssql
+```
+
+The tool asks for the target database when no argument is provided, then asks for the output path. Press `Enter` to accept the default path derived from the `PeopleDataGenerator` folder.
+

+# Docker Definitions
+
+This folder contains local Docker-based infrastructure definitions used by the teaching materials in this repository.
+
+## Available Setups
+
+- [postgres-eventsdb](docker-definitions/postgres-eventsdb): the main PostgreSQL database for application runs
+- [mssql-eventsdb](docker-definitions/mssql-eventsdb): the same teaching database adapted for Microsoft SQL Server with Full-Text Search
+
+## What The Containers Provide
+
+- initialized PostgreSQL instances
+- initialized Microsoft SQL Server instances
+- schema creation through startup scripts in each `init` directory
+- seed data used by the examples
+
+## Important Files
+
+For each PostgreSQL setup:
+
+- `.env.example`: committed template for local container settings such as ports, usernames, and passwords
+- `.env`: local copy created from `.env.example`
+- `docker-compose.yml`: service definitions
+- `init`: startup scripts copied into `/docker-entrypoint-initdb.d`
+- `backup`: optional location for backup files
+
+Before starting a setup for the first time, copy the example file in that folder:
+
+```powershell
+Copy-Item docker-definitions\postgres-eventsdb\.env.example docker-definitions\postgres-eventsdb\.env
+Copy-Item docker-definitions\mssql-eventsdb\.env.example docker-definitions\mssql-eventsdb\.env
+```
+
+On Linux and macOS, make sure the shell scripts in each `init` folder are executable before starting the containers:
+
+```bash
+chmod +x docker-definitions/postgres-eventsdb/init/*.sh
+```
+
+## Running The Main Database
+
+For normal day-to-day startup, use:
+
+```powershell
+docker compose -f docker-definitions\postgres-eventsdb\docker-compose.yml up -d
+docker compose -f docker-definitions\mssql-eventsdb\docker-compose.yml up -d
+```
+
+For `mssql-eventsdb`, use `--build` when you changed the Docker image setup, for example:
+
+- `Dockerfile`
+- files in `scripts`
+- initialization logic that depends on the image contents
+
+```powershell
+docker compose -f docker-definitions\mssql-eventsdb\docker-compose.yml up -d --build
+```
+
+To stop the containers without deleting named volumes:
+
+```powershell
+docker compose -f docker-definitions\postgres-eventsdb\docker-compose.yml down
+docker compose -f docker-definitions\mssql-eventsdb\docker-compose.yml down
+```
+
+To stop the containers and also remove named volumes:
+
+```powershell
+docker compose -f docker-definitions\postgres-eventsdb\docker-compose.yml down -v
+docker compose -f docker-definitions\mssql-eventsdb\docker-compose.yml down -v
+```
+
+`-v` removes the named Docker volumes created by the setup, which also deletes the persisted database files. Use it only when you want a clean re-initialization.
+
+The named database volumes use the `pi_` prefix to reduce the chance of accidental reuse across unrelated Docker setups.
+
+Default services:
+
+- PostgreSQL on port `5432`
+- local PostgreSQL backup folder mounted from `docker-definitions\postgres-eventsdb\backup` to `/backup`
+- Microsoft SQL Server on port `1433`
+- local SQL Server backup folder mounted from `docker-definitions\mssql-eventsdb\backup` to `/var/opt/mssql/backup`
+
+## Configuration Notes
+
+- review the `.env` files before sharing or reusing the setup outside local teaching and demo environments
+- application projects connect with the `sport` user created by the initialization scripts
+- if you change ports or passwords in `.env`, update the matching `dotnet user-secrets` connection strings as well
+- the SQL Server setup uses `Croatian_100_CI_AS_SC_UTF8` collation and has the Full-Text Search package installed, but no runtime full-text checks, catalogs, or indexes are created by default
+
+## Troubleshooting
+
+- If the database is not initialized as expected, remove the Docker volume and recreate the container so the init scripts run again
