インデックス

いんでっくす · Index (database)

Also known as: DBMS インデックス

An auxiliary data structure in a DBMS that is created on specific columns to speed up data retrieval. By using an index, the database can locate target records without performing a full table scan. Because too many indexes increase the overhead of write operations, indexes are typically created only on frequently queried columns.
