Database structure: the building blocks of a database The next step is to lay out a visual representation of your database. To do that, you need to understand exactly how relational databases are structured. Within a database, related data are grouped into tables, each of which consists of...

In Section “Database storage structure” we review the principles of page-based data storage in relational databases and define the parameters for parsing and recovering these pages. In the same section we also summarize important database-specific storage structures (i.e., non-tables) and ...
Chapter 2: Relational Model The Project Management Framework Workflow-Instance Model Interaction Methodology – Physical Database Design for Relational Databases Appendix D: Network Model Array Array is a variable which holds multiple values (elements) of similar data types. All the values are ...
NIBGF is comparable to aB-tree performance as far as the index is concerned, even in the worst case scenario, and to the BANG file performance as far as the data regions are concerned. These properties make the new structure suitable for efficient implementation of relational database ...
Storing a predicate like hasSimilarity for each pair of molecules in a database is not only impractical, but technically impossible if the predicate should match structures not present in the databases (e. g. arbitrary structures defined by SMILES). In classical SQL-based relational databases, ...
An embodiment is related to a database system for protecting data privacy and efficient organization of data. An enhanced database system comprises a DBMS, a data classifier, a data
A method of constructing an aid to tuning of database statements comprises a data structure (stored in a memory on a computer system) which compactly represents that information which is needed about a database statement to determine the optimal series of operations (e.g., table data fetches)...
