Based on the inspection of the README file and the two CSV dataset files, the following issues have been identified:

1. **Inconsistent Column Naming Across Datasets**

    - **Issue**: The two CSV files have inconsistent column names and structure.
    - **Evidence**: In "GP Orders - 2.csv", we have columns named `Order Number`, `Order Status`, `Book Name`, `Order Date`, and `City (Billing)`, while in "GP Orders - 5.csv", there are columns named `ï»¿Order Number`, `Order Status`, `Book Name`, `Order Date & Time`, among others including `City`, `Payment Method`, `Total items`, and `Total weight (grams)`.
    - **Description**: The structure inconsistency across datasets (column names and presence of additional data points such as `Payment Method`, `Total items`, and `Total weight (grams)` only in "GP Orders - 5.csv") suggests a potential for data integration and analysis challenges. This could lead to incorrect data interpretations or comparisons if not standardized. Furthermore, the column `ï»¿Order Number` in "GP Orders - 5.csv" appears to have a Byte Order Mark (BOM) or encoding artifact that should be corrected for consistency and compatibility.

2. **Encoding Issue Causing Inconsistent Data Representation**

    - **Issue**: Presence of non-standard characters in datasets indicating potential encoding issues.
    - **Evidence**: In "GP Orders - 2.csv", `Book Name` column contains names like `??????? ?? ???? ??????`, which suggests encoding issues or the use of characters not represented correctly in the dataset's encoding format.
    - **Description**: Encoding inconsistencies may result in the misrepresentation of non-ASCII characters, potentially leading to incorrect or lost data when processing. This issue is particularly evident in dataset fields containing text in languages other than English (e.g., Urdu names in the `Book Name` column), which should be handled correctly to ensure data integrity and meaningful analysis.

3. **Inconsistent Date-Time Formatting**

    - **Issue**: Different date-time formats across the datasets.
    - **Evidence**: "GP Orders - 2.csv" records orders with `Order Date` separated from time (e.g., `1/20/2021 17:43`), whereas "GP Orders - 5.csv" combines date and time in `Order Date & Time` (e.g., `2019-10-03 15:03`).
    - **Description**: The inconsistency in date-time representation across the datasets can cause issues in data processing and analysis, particularly when trying to perform time series analyses or integrating data from multiple sources. Standardizing the date-time format would facilitate more accurate and efficient data manipulation and analysis tasks.

These identified issues regarding data inconsistency significantly affect the datasets' usability for analysis, requiring data cleaning and standardization efforts to ensure accuracy and reliability in insights derived from the datasets.
