36. A programming language designed for managing & obtaining data in relational database management systems (RDBMS)






37. Guidelines set in place to ensure the trustworthiness of data over its entire life cycle.






38. A graphical representation of entities and their relationship to each other - typically used in computing in regard to the organization of data within databases or information systems
