Data structures

A data structure is a particular way storing and organizing data in a computer for efficient access and modification. Data structures are designed for a specific purpose. Examples include arrays, linked lists, and classes.

I have developed a database system called DSDB that is capable of storing data in multiple files within the computer's file system. The DSDB system utilizes B-trees, AVL trees, and Red-Black trees to index the data stored in the files. This indexing mechanism ensures that various operations can be performed on the data effectively and efficiently.
