# Data Extraction:
1. ### Add Dataset
    This option allows you to choose a dataset different from the current one to perform various operations such as joins, unions, and more.

2. ### Split Dataset
    This is used to divide a single dataset into multiple datasets, following the method specified by the user.
    1. #### Row Based Split:
        The dataset will be split based on the ratio provided by the user.\
        **Example:**\
        If the dataset contains 8 rows and the ratio is set as 1:3:4, the dataset will be split into three datasets with 1, 3, and 4 rows respectively.
    2. #### Column Based Split:
        The dataset will be divided based on the column selected by the user.
