Cardinality is a mathematics term that refers to the number of unique elements in a set. It is a concept deeply rooted in set theory, a branch of mathematical logic that studies collections of objects. In the context of data, cardinality refers to the uniqueness of data values contained in...
In this blog post we’ll define cardinality and high cardinality, and explore the role of cardinality in monitoring and observability.
In that setup, each customer has one identity card, and that card is linked to the customer through a one-to-one cardinality model between database tables. So every search can target the specific single card held in the secondary database table according to the subject, the individual custome...
Cardinality is a mathematical term. It translates into the number of elements in a set. In databases, cardinality refers to the relationships between the data in two database tables. Cardinality defines how many instances of one entity are related to instances of another entity. Below, we give ...
RDBMS stands for Relational Database Management System which stores data into tables, which consist of rows and columns. Learn What is RDBMS.
Data modeling (data modelling) is the process of creating a data model for the data to be stored in a database.
High-cardinality data, characterized by large numbers of unique values, represents both an opportunity and a challenge for modern data systems. While it enables more precise analysis and deeper insights, it also requires careful consideration of how to manage and query the data efficiently. The key...
Understand the data you’re trying to visualize, including its size and cardinality (the uniqueness of data values in a column). Determine what you’re trying to visualize and what kind of information you want to communicate. Know your audience and understand how it processes visual information....
What is the purpose of a database, and how does the database accomplish this purpose? How does a DBMS provide data security? What is data integrity? How does cardinality affect database design? Primary keys enforce which of the following? (a) referential integrity (b) entity ...
Data profiling, or data archeology, is the process of reviewing and cleansing data to better understand how it’s structured and maintain data quality standards.
