Exam 3: Architecture and Configuration
What are the two basic building blocks of a database? Describe them.
The basic building blocks of a database are tables and indexes. A table is a collection of data stored in a database. In a relational database, tables are typically designed to model real-world objects and the relationships that exist between them. A table is organized as a two-dimensional structure consisting of rows and columns. A database index is a logical database structure used to improve the speed and efficiency of data access. database index is constructed based on a unique key, and it contains pointers to the underlying rows within the table that match the key.
