Conversation to First Normal Form (1NF)

Step two: Identification of the Primary Key For maintenance of primary key, it is important to identify uniquely attributed value Step Three: Identifying all Dependencies Dependency diagrams can be significant obtaining a ‘bird's-eyesight’ of all the relations involved in the tables attribute, and their implication makes it less likely for an overlook of important decencies

Converting to Second Normal Form (2NF)

The relational database when designed has the possibility of being easily improved through conversion of the database to a format identified as the 2NF (Chapple, 2011). To ensure the effectiveness of the 2NF format, it is important first to ensure elimination of all partial ...

According to United Nations report (UNDP 7) on urbanization trends around the world, urban population has surpassed rural population between the years 2000 to 2005 and will continue to do so. The North America is at the top of the list as the most urbanized continent with 82 percent living in cities, followed by Latin America and the Caribbean with 80 percent and Europe with 70 percent (UNDP 1). The report predicted that by 2050 the world will be one-third rural (34 percent of the population) and two-thirds urban (66 percent of the population). Evidently, there is an increasing ...

Hospice caregiving is described as that which is patient and also family centred in a way that it is designed to cater for the needs of the patients (the survivor) as well as the needs of the caregiver.

Such philosophical deviations were caused by the separate development of religious groups in different regions. According to karmic reincarnation in Hinduism, the fate of the Atman (soul) in each new life depends on its actions done during the previous incarnations. The law of karma states that ...

Consider an application that requires an encryption and MAC algorithm be implemented on a processor with a small amount of non-volatile memory. The only cryptographic algorithm that the processor can compute is Triple-DES. But you have space for one 168-bit key. Describe how it is possible to both encrypt and MAC using only a single key. Justify your answer and state any assumptions you use. Using a small non-volatile memory will require the key to be externally generated so that they can be amassed on the non-volatile memory (Gilardi and Serpanos, 2006). Since the key size is 168bits, the keys will be ...
