Säilytystietomallit, or storage data models, refer to the conceptual and logical structures used to organize and manage data within storage systems. These models define how data is represented, accessed, and manipulated, influencing the performance, scalability, and efficiency of the storage solution. Different types of storage technologies employ distinct data models tailored to their specific characteristics. For instance, file-based storage typically uses a hierarchical directory structure, where data is organized into files and folders. Block-based storage, common in SANs (Storage Area Networks), treats data as fixed-size blocks that are addressed by their physical location. Object storage, on the other hand, organizes data into discrete units called objects, each with a unique identifier, metadata, and the data itself. This approach offers greater flexibility and scalability, particularly for unstructured data. Databases also utilize their own sophisticated data models, such as relational models with tables, rows, and columns, or NoSQL models like document, key-value, or graph models, each optimized for specific types of data and query patterns. The choice of a storage data model is critical for ensuring data integrity, optimizing retrieval times, and supporting the overall application requirements. Understanding these models is fundamental to designing and managing effective data storage infrastructures.
