Anchor modeling is a novel data warehouse modeling technique, designed for classical databases and adapted by the authors of the article for Big Data An anchor model is a relational database schema that displays a high degree of normalization, reuse of data and the ability to store historical data. What does this mean? Not sure about the normal forms? See the Anchor Modeling separates stable identifiers (anchors) from their descriptive data (attributes), enabling scalable, time-aware models. The basic premise of Anchor Modeling is that it offers non Anchor Modeling is an agile data modeling technique that is specifically designed to handle evolving data structures. The relationship between anchor modeling and traditional conceptual modeling techniques for relational databases, such as ER, EER, UML, and ORM, is describe Anchor modelling structures data into anchors, attributes, ties, and knots, which allow data models to be modified, expanded, or adapted over time without requiring changes 2. Among these are Data Vault modeling and Anchor modeling. In the In this paper, we propose a modeling technique for data warehousing, called anchor modeling, that offers non-destructive extensibility mechanisms, thereby enabling robust and flexible Temporal Complexity Having taken a deep dive into our convenience functionalities that aim to remove most obstacles for working with temporal data, I anew “appreciated” the underlying Short question related to official anchor modeler.

Abstract Normally querying data in an Anchor modeled database falls within two categories: OLTP-like queries, retrieving a large number of attributes using high selectivity conditions Thanks to the high degree of normalization in an anchor model together with strong typing our data is stored very efficiently. The main concepts of the model include: Anchor – represents an entity or event, contains surrogate keys and (optionally) a timestamp for when the record was added. The two techniques Anchor modeling and Data Vault are related, both being forms of Ensemble modeling, but still have many differences.
