The rule for first normal form (1NF) is a table in which the intersection of every column and record contains only one value. In other words a table that contains more than one atomic value in the intersection of one or more column for one or more records is not in 1NF. The non 1NF table can be converted to 1NF by restructuring original table by removing the column with the multi-values along with a copy of the primary key to create a new table. See Figure 8.4 for an example of this approach.…

Answer: In this modern day, databases are based heavily on relational models in which tables are the fundamental building blocks. We may ask the question as to where ER comes in database design, its importance and the need for ER modelling in modern databases. In an attempt to answer these questions, we get to understand that ER is a high-level description of the proposed database, useful for understanding the requirements gathered from a client, in our case The Reproduction Antiques Company. It…

What is a relational database? It is a database that stores the information about both data, for example for a person detail that is link with their car details that they have bought it from the company.

According to (Connolly, 2003) the database is “A shared collection of logically related data, and a description of this data, designed to meet the information needs of an organization”. The Database Management System (DBMS) is software that enables users to define, create, maintain and control access to the database. The database has identified three levels of abstraction. All these three levels will have different aspects and they are as follows: • Physical or external level- The database…

vital information of real-time events. The objective requires managing personal cognizant comportment for integrating vital information. The standard utilizer and application (APP) program interface to a relational database is the Structured Query Language (SQL) (Codd, 2003-2016). The APP retrieves and supplies the information from the graph table to structure the database (Haag, & Cummings, 2013). Therefore, the advantage to decipher information is an outline in light of the facts, which the…

The theory of Continuous Auditing was established by Vasarhelyi and Halper (1991). Continuous auditing entails the real-time monitoring and analysis of the entire population of records. The premise of this methodology is based on the concept of “audit by exception” where deviations (e.g. control variances) are flagged as alerts and forwarded to the responsible parties (e.g. management, internal auditors, business owners) for investigation. Continuous auditing has evolved from an academic theory…
