Final answer:
To begin developing a data dictionary, an organization must first determine the system of interest and identify the relevant information and quantities that need definition or calculation. This entails understanding the scope and gathering foundational information for data dictionary entries.
Step-by-step explanation:
The first step an organization should take when developing a data dictionary is to determine the system of interest and identify the information that is given and what quantity or information needs to be calculated or defined. A clear grasp of the system's scope will help in outlining what data is to be included in the data dictionary. After that, it is essential to gather necessary information, such as reviewing existing documentation, interviewing stakeholders, and analyzing current data models, which will serve as the foundation for the data dictionary entries.
Once the system of interest is well-understood, and the relevant information is identified, the next steps would include defining data elements, establishing consistent naming conventions, and specifying the attributes and relationships of each data element within the system.
