+1. [Install DBeaver](#install-dbeaver)
+
+
+## Install DBeaver
+
+DBeaver is free and open source universal database tool for developers and database administrators. It supports several databases including MySQL, Oracle and Postgresql. It can be used as an alternative of MySQL-Workbench and PGAdmin. It has a user-friendly interface that makes it more useful for its new users. Using DBeaver, you can create local databases and also configure the maximum result size to avoid session hanging issues in case the query results take time to process big queries. The community edition of DBeaver is free, though if you'd like to do NoSQL then you may opt for the enterprise version.
+
+### Using the Terminal
+
+OpenJDK is the default Java development and runtime available on Debian repository. Run the following commands to have Java installed and set as default Java on your Ubuntu:
+
+```python
+sudo apt update
+sudo apt -y install default-jdk
+```
+
+Once that is done, you can check the version by running:
+
+```python
+$ java --version
+
+# Output
+
+openjdk 11.0.16 2022-07-19
+OpenJDK Runtime Environment (build 11.0.16+8-post-Ubuntu-0ubuntu120.04)
+OpenJDK 64-Bit Server VM (build 11.0.16+8-post-Ubuntu-0ubuntu120.04, mixed mode, sharing)
+```
+
+Add DBeaver repository to your Debian / Ubuntu by running the commands below:
+
+```python
+wget -O - https://dbeaver.io/debs/dbeaver.gpg.key | sudo apt-key add -
+
+echo "deb https://dbeaver.io/debs/dbeaver-ce /" | sudo tee /etc/apt/sources.list.d/dbeaver.list
+```
+
+After adding the repo, update the apt list and install DBeaver CE:
+
+```python
+sudo apt update
+
+sudo apt install dbeaver-ce
+```
+
+
+Once the installation is complete, you can start DBeaver by typing `dbeaver-ce` in the terminal. You should see DBeaver launching.
