MongoDB was born as a Big Data database, unlike traditional relational databases which were built for other purposes and later adapted for Big Data needs. The company's general-purpose database is designed to handle a wide variety of data types and sources in real-time at significant scale, making it well-suited for Big Data applications. MongoDB has been continuously adding features relevant to Big Data, such as full-text indexing, but its fundamental capabilities were always intended to be applicable to a broad range of applications.
