DBest provides support for working with CSV files. Follow these steps to import and manage CSV files in the tool:

• Use the "Open CSV" option in the menu and select the desired CSV file.
• Alternatively, drag and drop a CSV file directly into the tree editor panel.

When a file is selected, a wizard will appear, prompting you to specify parsing properties, such as:

• Delimiter (e.g., ,, ;, or \t)
• Starting Line (indicating where the data begins)

Once the properties are set, the tool will display the CSV in a tabular format. Each column will be assigned a type, which you can adjust to a more generic type if necessary.

The table view provides a clear representation of the CSV data, along with the inferred column types. A snapshot of the tool in action is shown below:

Upon completing the importation process, DBest generates a header file in the same directory as the CSV file. The header file:

• Is named after the CSV file, with a .head extension (e.g., data.csv creates data.head).
• Stores metadata such as the delimiter and column types used during import.

This header file allows for faster re-importation of the CSV file. You can reopen it using the "Open DBest header file " menu option or by dragging and dropping it into the tree editor panel.

Once imported, the CSV node will appear in the left-side panel. To work with it:

1. Drag the CSV node to the editor panel.
2. Open the node using one of these methods:
   • Double-click the node.
   • Right-click the node and select "Run Query".

Both methods allow you to navigate through the records efficiently.
