It is nearly impossible to consider all the different ways that program execution in different threads could overlap with each other, and how different types of overlap can lead to different final states. Instead, database systems provide a beautiful abstraction to the application developer—a “...
. The highest level of abstraction describes only part of the entire database. Even though the logical level uses simpler structures, complexity remains because of the variety of information stored in a large database. Many users of the database system do not need all this information; instead,...

We argue that the design of security aspects should be considered together with the conceptual modeling of ...
The following table provides a clear overview of how the three levels of database design differ in terms of their purpose, focus, independence from specific DBMS, modeling tools, and examples of attributes, relationships, and keys at each level. Understanding these distinctions is essential ...
