Final answer:
The missing word in the sentence is 'action'. Action queries in RDBMS allow for updating, deleting, and creating records in the database, and they stand in contrast to select queries that only retrieve data.
Step-by-step explanation:
Among the different types of RDBMS query tools, the missing word completing the sentence "Those query tools include crosstab queries, ________ queries, parameter queries, and queries specific to SQL" is action. Action queries are designed to modify sets of data by updating, deleting, or creating new records. These are in contrast to select queries, which are used just to retrieve data without altering the database.
Action queries are powerful tools in RDBMS as they enable users to automate large-scale changes to data within their databases. In the context of SQL, common types of action queries include UPDATE, DELETE, INSERT, and CREATE. It is essential to use these queries with caution, as they can significantly alter the database's contents.
