HBase data model is a distributed, column-oriented database built on top of Hadoop. It stores data in tables, with rows identified by a row key. Each table consists of one or more column families, where columns are organized hierarchically into column qualifiers. Column values can be stored as simple data types like strings, integers, and floats, or complex types like lists and maps.
