A foreign key constraint is used to represent a relationship in a RDBMS (relational database management system).
Basically data types are divided into three types namely, 1. primary data type -> this is sub divide into int, float, char, void. 2. derived data type -> this is sub divide into array, pointer. 3. user defined data type -> this is sub divide into struct, union, enum, typedef. by, k.p.sruthi
It is possible to explain data structure in layman's terms. Simply put, in computer terms, a data structure is a commonly used method of data organization.
Which data type is the only one that can be used in calculations?
Economic forecasting models predominantly use time-series data, where the values of the variables change over time.
There is no such data type. However, when we use user-defined data types of our own type, then that type of data can be stored in a variable. So as a term, you may say that user-defined data type can store any data. As the data-type used in any variable will be depending upon us.
right answer is in the sky.
Entity-Relationship diagrams are useful for modelling data and the relationships between the data. They can be used when the constraints between data are relatively simple. They do not allow specification of interactions between the data or model how the data changes (there are no processes in Entity-Relationship). Entity-Relationship diagrams are most often used to model databases.

Deterministic relationship refers to a cause-and-effect connection between variables, where one variable directly influences the other. In data analysis, understanding deterministic relationships helps in making accurate predictions and decisions based on the data, as it allows for the identification of patterns and trends that can be used to explain and predict outcomes.
