A Unique Index enforces distinct values in a column, preventing duplicates while speeding up queries. It's ideal for fields like email or username, ensuring data accuracy with minimal impact on read performance.- Published on
A Non-Clustered Index is a separate data structure that stores column values and pointers to table rows, speeding up lookups without altering the table's physical order. Multiple non-clustered indexes can exist per table to optimize diverse queries.- Published on
Learn the key differences between synchronous and asynchronous communication. Discover when to use each method with examples, pros/cons, and best practices for developers.- Published on
A Clustered Index controls the physical order of data in a table, making range queries and sorting extremely fast. It organizes rows on disk by the index key and is usually the primary key, with only one clustered index allowed per table.
