vertikaalidatan

Vertikaalidatan, also known as vertical data, refers to the organization of data in a database where each data type or attribute is stored in a separate table. This approach contrasts with horizontal data, where all attributes of a single entity are stored in a single table. In a vertically-oriented database, each column in the database represents a single attribute, and each row represents a single value for that attribute.

The primary advantage of vertikaalidatan is its efficiency in read operations. Since each attribute is stored separately, retrieving specific data types can be faster and more efficient. This is particularly beneficial for analytical queries that focus on a single attribute or a small set of attributes. However, this structure can be less efficient for write operations, as updating or inserting data requires modifying multiple tables.

Vertikaalidatan is commonly used in data warehousing and big data environments where read-heavy operations are prevalent. It is also employed in columnar databases, which are designed to optimize the storage and retrieval of data in columns rather than rows. Examples of columnar databases include Apache Cassandra and Google Bigtable.

In summary, vertikaalidatan is a data organization method that separates each attribute into its own table, optimizing read operations but potentially complicating write operations. It is particularly suited for environments where read-heavy queries are common.
