Datakantatyyppejä

Datakantatyyppejä refers to the various ways data can be structured and organized within a database. Understanding these data types is crucial for efficient storage, retrieval, and manipulation of information.

Common data types include primitive types like integers (whole numbers), floating-point numbers (numbers with decimal points), and booleans (true or false values). Strings are used to store text.

More complex data types exist, such as dates and times, which allow for temporal data storage and operations. Binary large objects (BLOBs) are used for storing large unstructured data like images or audio files.

Databases also support structured types like arrays, which are ordered collections of elements, and objects or records, which group multiple fields together to represent a single entity. The choice of data type impacts performance, storage requirements, and the types of operations that can be performed on the data. Different database systems may offer slightly different implementations or additional specialized data types. For instance, some databases support spatial data types for geographic information.
