‘Database ER Diagram Architecture’™

The following database engineering architecture can be used to both visually represent the building blocks (schemas) for software applications (software computer) or for the development of integrated circuitry (IC) firmware (hardware schema) engineering. The IC firmware, ER Diagrams can be analysed to plan IC hardware.

Each stage of the database above is a database of records which follow each other in sequential logic, such as name database, date of birth database, phone number, database etc.

All sequential logic is known as a clock or clock signal. Databases are clock signal management systems. Narrow band or series logic is the most appropriate for security applications.

Serial database is a single database row. Tables are many rows. Each database, shift register element is database column. It may operate in serial as a row or in parallel as a table. One further example is each register as a series of inner-join queried tables. Each example, including each row cell is a database.

Despite earlier database theory, all outer-join database must occur at the inner-join. Without the inner join, the database is an array of non-relational (disconnected) data. The database is named after the outer-join side, read from left to right.

With the three database structures which comprise ER Diagram (Entity-Relationship Diagram) Database Architecture, any database architecture can be developed. ERD constraints may be included from the beginning, or at the final ERD phase. For versatility, in the instructive diagram, no constraints such as crowsfeet are included.

For security applications, Xerqon recommends that an unpredicatble combination and permutaition of the database structures be used to develop an API (application programming interface).
