    Question

    Which format is best suited for organizing customer complaints recorded in text format, including emails and social media messages?

    A Structured data, because it is easily searchable in a database. Correct Answer Incorrect Answer
    B Semi-structured data, since it has some level of organization but is not fully structured. Correct Answer Incorrect Answer
    C Unstructured data, as it is raw text without a predefined structure. Correct Answer Incorrect Answer
    D Data stored in relational databases, which can handle text data efficiently. Correct Answer Incorrect Answer
    E Numerical data format, because it can be easily quantified and analyzed. Correct Answer Incorrect Answer

    Solution

    Customer complaints in text form, such as emails and social media posts, fall under unstructured data. This format lacks a fixed organizational framework, making it difficult to store in a tabular or relational database without transformation. Text data requires advanced techniques, like natural language processing (NLP), to extract insights, as it doesn’t follow a pre-set structure like structured data or partially organized format like semi-structured data. Organizations typically use big data tools to manage and analyze unstructured data due to its complex nature. Option A is incorrect as structured data has predefined fields and is unsuitable for raw text data. Option B is incorrect because semi-structured data has some inherent organization (like JSON or XML) which doesn’t fit plain text. Option D is incorrect because relational databases handle structured data well, but unstructured data requires different tools. Option E is incorrect since numerical data lacks relevance to raw textual information.
