Laboratory, proposed a new data representation framework called the relational data model This proved to be a watershed in the development of database systems: it sparked rapid development of several DBMSs based on the relational model, along with a rich body of theoretical results that placed the field on a firm foundation Codd won the 1981 Turing Award for his seminal work Database systems matured as an academic... 595 597 598 600 601 601 602 602 xvii Contents 21.4 21.5 21.6 21.7 21.8 21.9 21.10 21.11 21.12 21.13 21.14 21.3.2 Sorting 21.3.3 Joins Parallel Query Optimization Introduction to Distributed Databases 21.5.1 Types of Distributed Databases Distributed DBMS Architectures 21.6.1 Client-Server Systems 21.6.2 Collaborating Server Systems 21.6.3 Middleware Systems Storing Data in a Distributed DBMS 21.7.1 Fragmentation... to be annoyed I’d like to thank my family for being there and giving meaning to everything I do (There!
