andmebaase

Andmebaase is the Estonian plural form of andmebaas, referring to databases. In computing, a database is a structured collection of data stored and managed by a database management system (DBMS). Databases enable applications to store, retrieve, update, and organize information efficiently, supporting operations from simple websites to complex enterprise systems.

Databases are built on data models. Relational databases use a fixed schema of tables with columns and rows and rely on Structured Query Language (SQL) for data access. Non-relational or NoSQL databases use document, key-value, columnar, or graph data models, each optimized for different workloads, flexibility, and scalability patterns.

A typical database system comprises storage, a query processor, a transaction manager, and a metadata catalog. It handles data integrity through transactions, concurrency control, and recovery. ACID properties are common in many relational DBMS, while some NoSQL systems emphasize eventual consistency (BASE) to improve performance and scalability in distributed environments.

Deployment approaches vary: on-premises, cloud-based managed services, or hybrid configurations. Features such as replication, sharding, backups, and point-in-time recovery contribute to availability and durability. Security practices include authentication, authorization, encryption at rest and in transit, and auditing of access and changes.

In practice, an andmebaas is selected based on data structure, access patterns, and scalability needs. The term is used primarily in Estonian-speaking contexts; in English, the standard term is database. The plural form andmebaase may appear in documentation referring to multiple databases.
