Reversible Numeric Composite Key (RNCK)
share
In database design, Composite Keys are used to uniquely identify records and prevent data duplication. However, they require more memory and storage space than single keys, and can make queries more CPU-intensive. Surrogate Keys are an alternative that can overcome some of these limitations, but they can also introduce new disadvantages. To address these challenges, a new type of key called a Reversible Numeric Composite Key (RNCK) has been developed. RNCK is a single number that encodes multiple data attributes, and can be decoded back to the original values. This makes it possible to achieve the benefits of both Composite Keys and Surrogate Keys, while overcoming some of their limitations. RNCK has been shown to improve query performance and reduce memory and storage requirements. It can be used in relational databases, large static datasets, and key-value caching systems. RNCK has been successfully used in production systems for several years.
