FranActive data dictionary is constantly updated and reflects real-time changes within a database or system, while passive data dictionary is static and does not change unless manually updated. Active data dictionary is dynamic and integral to system operations, providing current information about data elements, relationships, and structures. Passive data dictionary is more archival in nature, serving as a reference for historical data definitions and structures.

The difference between active and passive monitoring sampling?
Active Sampling refers to the process of connecting sample collection media (i.e., thermal desorption tube) to a sampling train consisting of inert tubing and a sample pump operating at a know flow rate. Once activated, the sample pump draws air through the sample media, resulting in a know sample volume. Passive Sampling refers to the process of allowing sample collection media (i.e., thermal desorption tube) to passively diffuse air through the sample media without benefit of 'forced air'. This allows for longer potential sample periods without concern for overloading the sampling media. •

What type of listening is most appropriate during a group discussion?

It involves providing feedback, asking clarifying questions, and showing empathy to foster effective communication within the group.
What is the difference between common name and scientific name?
Common names are what the most of us use. Scientific names are what scientists use to differentiate, one from another in the classification system. The difference is precision: the scientific name is an attempt to remove as much ambiguity as possible, in order to avoid confusion. This level of precision is not usually needed in most circumstances and common names are easier to remember and pronounce. The important thing to remember is that everyone wants others to understand what they're saying, so everyone tries to use terms that have have the best chance to accomplish that goal.
