```
2. Ensure execution permissions:
```bash
chmod +x CLI-Version/*.sh GUI-Version/*.sh
```
## Usage
### CLI Version
Run the main menu:
```bash
./CLI-Version/Main_Menu.sh
```
### GUI Version
Run the GUI version using `Zenity`:
```bash
./GUI-Version/Main_Menu.sh
```
## Database Operations
### Creating a Database
- In CLI: Choose `Create Database` from the main menu and enter a name.
- In GUI: Enter the database name in the prompt.
### Creating a Table
- Define table name, columns, and primary key.
- Supported data types: `num`, `str`, `date`.
### Inserting Data
- Records must match the table schema.
- Primary keys must be unique.
### Selecting Data
- Supports full table selection or filtering by column values.
### Updating & Deleting Data
- Users can update or delete records based on column conditions.
## Validation Rules
- Database/Table names must start with a letter and can contain `[a-zA-Z0-9_#@$]`.
