+# Switching to a Different Database in Geoweaver
+
+## Introduction
+In this guide, we will walk you through the steps to switch the database used by Geoweaver to either PostgreSQL or MySQL. Follow the instructions for your preferred database below.
+
+## Switching to PostgreSQL
+
+### Step 1: Install PostgreSQL
+
+Ensure PostgreSQL is installed on your system. You can download it from the [official PostgreSQL website](https://www.postgresql.org/download/).
+
+### Step 2: Create a Database and User
+
+Open the PostgreSQL shell or use a database management tool like pgAdmin. Run the following commands to create a new database and user:
+
+```sql
+CREATE DATABASE geoweaver_db;
+CREATE USER geoweaver_user WITH ENCRYPTED PASSWORD 'your_password';
+GRANT ALL PRIVILEGES ON DATABASE geoweaver_db TO geoweaver_user;
+```
+enter \q to exit from the postgres shell
+
+### Step 3: Create and Configure application.properties File
+
+
+
+**Windows** 
+
+- Open command prompt, navigate to home directory and create the `geoweaver` directory
+
+```shell
+cd %HOMEPATH%
+mkdir geoweaver
+cd geoweaver
+```
+
+- Create a new application.properties file using Notepad: 
+
+```shell
+notepad application.properties
+```
+
+- Add the PostgreSQL configuration:
+
+```text
+spring.datasource.url=jdbc:postgresql://localhost:5432/geoweaver_db
+spring.datasource.username=geoweaver_user
+spring.datasource.password=your_password
+spring.datasource.driver-class-name=org.postgresql.Driver
+spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect
+```
+
+- Save and close the file.
+
+**Linux and Mac:** 
+
+- Open a terminal, Navigate to your home directory and Create the `geoweaver` directory:
+
+```shell
+cd ~
+mkdir geoweaver
+cd geoweaver
+```
+
+- Create a new application.properties file using a text editor. For example, using nano:
+
+```shell
+nano application.properties
+```
+
+- Add the PostgreSQL configuration:
+
+```text
+spring.datasource.url=jdbc:postgresql://localhost:5432/geoweaver_db
+spring.datasource.username=geoweaver_user
+spring.datasource.password=your_password
+spring.datasource.driver-class-name=org.postgresql.Driver
+spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect
+```
+- Save and close the file by pressing Ctrl + O, then Enter, and exit by pressing Ctrl + X.
+
+
+
+### Step 4: Restart Geoweaver
+Restart your Geoweaver application to apply the changes. Verify the connection by checking  accessing the application.

+
+## Switching to MySQL
+
+### Step 1: Install MySQL
+
+Ensure MySQL is installed on your system. You can download it from the [official MySQL website](https://dev.mysql.com/downloads/mysql/).
+
+
+### Step 2: Create a Database and User
+
+Open the MySQL shell or use a database management tool like MySQL Workbench. Run the following commands to create a new database and user:
+
+```sql
+CREATE DATABASE geoweaver_db;
+CREATE USER 'geoweaver_user'@'localhost' IDENTIFIED BY 'your_password';
+GRANT ALL PRIVILEGES ON geoweaver_db.* TO 'geoweaver_user'@'localhost';
+FLUSH PRIVILEGES;
+```
+
+
+### Step 3: Create and Configure application.properties File
+
+
+**Windows** 
+
+- Open command prompt, navigate to home directory and create the `geoweaver` directory
+
+```shell
+cd %HOMEPATH%
+mkdir geoweaver
+cd geoweaver
+```
+
+- Create a new application.properties file using Notepad: 
+
+```shell
+notepad application.properties
+```
+
+- Add the MySQL configuration:
+
+```text
+spring.datasource.url=jdbc:mysql://localhost:3306/geoweaver_db
+spring.datasource.username=geoweaver_user
+spring.datasource.password=your_password
+spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
+spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect
+```
+
+- Save and close the file.
+
+**Linux and Mac:** 
+
+- Open a terminal, Navigate to your home directory and Create the `geoweaver` directory:
+
+```shell
+cd ~
+mkdir geoweaver
+cd geoweaver
+```
+
+- Create a new application.properties file using a text editor. For example, using nano:
+
+```shell
+nano application.properties
+```
+
+- Add the MySQL configuration:
+
+```text
+spring.datasource.url=jdbc:mysql://localhost:3306/geoweaver_db
+spring.datasource.username=geoweaver_user
+spring.datasource.password=your_password
+spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
+spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect
+```
+- Save and close the file by pressing Ctrl + O, then Enter, and exit by pressing Ctrl + X.
+
+
+
+### Step 4: Restart Geoweaver
+Restart your Geoweaver application to apply the changes. Verify the connection by checking  accessing the application.
