Computer Science 282 Advanced Data Structures

Course Description: An exploration of advanced data structures (particularly persistent structures) using object-oriented design. An introduction to databases using Java. Course reviews main-memory data structures such as hash tables and trees. Disk-based structures such as persistent hash tables and indexed files. Architectural foundations for files, large scale sorting and serialization.
