How are regular and composite indexes implemented in RDBs? Code Answer

Hello Developer, Hope you guys are doing great. Today at Tutorial Guruji Official website, we are sharing the answer of How are regular and composite indexes implemented in RDBs? without wasting too much if your time.

The question is published on by Tutorial Guruji team.

In databases like MySQL or Oracle, how are indexes implemented? I think regular indexes are stored as B-trees, but couldn’t find anything about composite indexes that index on multiple columns. I’m looking for the names of the data structures used so I can research them.

More generally, where can I find more such information about database implementation details? I’m going to be taking a course on that much later in university, but I’m curious right now.

Answer

Composite indexes also use B-Trees, they just concatenate the indexed columns to determine the key. As a side node, Oracle also knows other index types, i.e. bitmap indexes. But that doesn’t depend on the number of columns indexed.
