Detailed explanation-1: -Non-relational (NoSQL) databases have emerged as a convenient way of storing unstructured big data. They are flexible, scalable, highly available, secure, and help to minimize the unstructured data storage challenges. NoSQL databases make data management more efficient and cost-effective.
Detailed explanation-2: -Structured data is usually easier to search and use, while unstructured data involves more complex search and analysis. Unstructured data requires processing to understand it, such as stacking before placing it in a relational database. Structured data is older, so there are more analytics tools available.
Detailed explanation-3: -Unstructured simply means that it is datasets (typical large collections of files) that aren’t stored in a structured database format. Unstructured data has an internal structure, but it’s not predefined through data models. It might be human generated, or machine generated in a textual or a non-textual format.
Detailed explanation-4: -Email: While we sometimes consider this semi-structured, email message fields are text fields that are not always easily analyzed. Multimedia content: Digital photos, audio, and video files are all unstructured.
