Analyselaag

Analyselaag is a software architecture layer dedicated to data analysis and insights generation. It sits between the data access layer and the presentation or domain logic layers, receiving raw data from data stores or streams, applying transformations, analytics models, and producing analytical results such as metrics, reports, scores, or alerts. The layer helps decouple data processing from business rules and UI concerns.

Key responsibilities include data cleansing and normalization, feature extraction, statistical analysis, model inference or scoring, aggregation, anomaly detection, and generation of dashboards or API outputs. It may host pipelines, libraries for machine learning and artificial intelligence, and reporting adapters; it provides APIs for other layers to request analytics results.

Typical components encompass data processing pipelines, an analytics models library, feature stores, results caches, visualization adapters, and scheduling or orchestration tools. The analyselaag is designed to be loosely coupled with the data access layer and the presentation layer, supporting asynchronous processing when analytics tasks are long-running.

Design considerations focus on performance and scalability, reproducibility and governance, and security and privacy. Other concerns include versioning and lifecycle management of analytics models, proper testing and monitoring, data quality controls, and clear error handling and observability to trace analytics results back to source data.

Examples of use include business intelligence platforms, e-commerce customer analytics, and IoT sensor analytics. The term can vary by organization and is often referred to as the analytics layer or data science layer in practice.
