MarkLogic provides native storage for JSON, XML, RDF, geospatial, and large binaries (e.g., PDFs, images, videos). With this approach, it is easy to get all of your data in, and easy to make changes later on. Relational databases require predefined schemas and complex ETL to store data in rows and columns. With MarkLogic, you can load all of your data as is, without cumbersome traditional ETL processes. MarkLogic stores your structured and unstructured data—and your data and metadata—all together in the same database. And, if you need to add another data source with a different schema later on, that is okay. In the words of one MarkLogic customer, MarkLogic’s flexible data model “removes the shackles of relational technology.”
