The Entity-Attribute-Value (EAV) data model is a design pattern to overcome the limitations of traditional relational databases. Its goal is to encode entities with a variable and a disparate number of attributes. It is efficient in terms of storage and it respects the rules of normalization. However, it doesn’t scale well, it degrades performance in […]
Window functions in PostgreSQL are a very useful tool; and since their introduction 10 years ago, they have been gradually adopted for various use cases where a simple aggregation is just not flexible enough — case in point, incremental totals and moving averages.
