Question

BlackTom AI · Accepted Answer

In this question, you’re evaluating the historical introduction of the relational database concept and its early development.
Option 1: '1970s' — This is the correct choice. The relational model was introduced by E. F. Codd in 1970, and relational database systems began appearing in the 1970s with research prototypes like IBM System R and early commercial products such as Oracle later in the decade.
Option 2: '1920s' — This is incorrect. The 1920s predates modern computer databases by several decades and is associated with early mechanized information handling, not relational database theory.
Option 3: '1940s' — This is also incorrect. While mechanization and early computing concepts appeared in the 1940s, the relational database model had not yet been formulated; databases then were flat-file or early hierarchical/network models.
Option 4: '1960s' — This is a tempting distractor, as computing advanced in the 1960s, but the formal relational model was introduced in 1970, not the 1960s. Databases in the 1960s were largely navigated using hierarchical or network structures rather than relational theory.
