dokumendibaasis

Dokumendibaasis is a type of NoSQL database designed to store, retrieve, and manage document-oriented information. In a dokumendibaasis, data is stored as documents, commonly encoded in JSON, BSON, or XML, and organized into collections. The schema is dynamic: documents in the same collection may have different structures, which allows flexible evolution of data models without predefined tables or columns.

Each document is a self-contained unit that can nest objects and arrays, representing rich, semi-structured data. The database uses indexes on document fields to enable fast lookups, and many implementations support secondary indexes, text search, and aggregation pipelines for data processing.

Querying in a dokumendibaasis typically uses a JSON-like query language or SQL-inspired syntax to filter, sort, and project fields. Many systems offer features such as multi-document transactions and tunable consistency models, enabling a balance between reliability and performance. Availability and durability are often achieved through replication and sharding, allowing horizontal scalability.

Common use cases include content catalogs, product catalogs, user profiles, session data, logging, and mobile or web applications where data naturally fits as documents rather than fixed rows. The flexible data model simplifies handling evolving requirements and nested data structures.

Examples of popular dokumendibaasis products include MongoDB, Couchbase, RavenDB, Amazon DocumentDB, and ArangoDB (a multi-model database). Advantages of this approach include schema flexibility, natural representation of nested data, and scalable throughput. Limitations can include data duplication, less suited support for complex relational queries, and a need for thoughtful indexing and data modeling to optimize performance.
