Which of the following is an open-source framework designed to handle unstructured and semi-structured data?

Question

To tackle this question, I’ll evaluate each option in turn and relate it to the concept of an open-source framework for unstructured and semi-structured data.
Option 1: eBay's "But it Now" feature. This is a specific e-commerce feature related to buying and selling items, not a data framework. It does not pertain to data processing or storage architectures, so it does not fit the description.
Option 2: OpenTable. OpenTable is a restaurant reservation system and database-driven service for scheduling tables. While it involves data, it is not an open-source framework and it is not designed as a general-purpose platform for handling unstructured or semi-structured data.
Option 3: Microsoft Excel. Excel is a spreadsheet application used for tabular data organization and analysis. It is proprietary software, and although it can store data, it is not an open-source framework nor specialized for unstructured/semi-structured data processing at scale.
Option 4: Hadoop. Hadoop is an open-source framework specifically created to store and process large-scale data, including unstructured and semi-structured formats, via distributed storage (HDFS) and processing (MapReduce, and later Spark integrations). Its design directly targets handling diverse data types across clusters, making it the correct match for the prompt.
In summary, only Hadoop fulfills both requirements—being open-source and oriented toward managing unstructured and semi-structured data—while the other options do not align with that description.
