Normalization is a technique mostly applied when the organization of tables in the database is necessary. One of its main objectives is to eliminate redundancy in the tables and ensure correctness of the anomalies in the insertion, updating and deleting of data from the tables. The process also ensures that the data dependency shared throughout a database makes sense and is logical. Once the process of normalization occurs, then it becomes very easy to update and delete records without necessarily worrying that any data might be lost (Kanade, Gopal, & Kanade, 2014). The process improves the design of the database ...

An entity relationship model/diagram commonly referred to as ERD is a data model method that represents system entities and relationships between the entities.

It’s a principle that provides the basic and the essential part in the mathematics of sorting and even counting. This principle was introduced by Johann Peter Gustav Lejeune Dirichlet in 1834. He called it the shelf principle or drawer principle. However, many people appreciate his insight and call it the Dirichlet drawer principle. The name pigeonhole was introduced in 1940 by Raphael Robinson. In the literal sense, pigeonholes refer to shelves or holes used to place pigeons. Thus, the principle roughly states that if one has a given number of boxes and a given number of items to ...

Cryptography can be simple described as “a technique of encoding and decoding messages, so that they cannot be understood by anybody except the sender and the intended recipient” (Godbole & Kahate, 2003). Symmetric and asymmetric encryptions are the two major technologies used by contemporary organizations to secure their data; hence offering particular advantages when compared. In symmetric key cryptography, encryption and decryption are executed using a similar key whereas two different keys are used for the mentioned purposes in asymmetric key cryptography. The encryption/decryption speed in symmetric key cryptography is considerably faster than that in asymmetric key cryptography. In comparison, ...

Compare and contrast symmetric and asymmetric encryption

Comparison Both the symmetric and the asymmetric encryption are means of securing communication between parties, especially in an enterprise. They function through encryption of plaintext and decryption of ciphertext to promote data integrity, confidentiality, and authentication (Sasi, Dixon, and Wilson, 2014).

Contrast

The symmetric encryption uses the same key for both encryption and decryption operations. On the contrary, asymmetric encryption (public-key encryption) uses a pair of keys, one for the public and the other one for private use. The communication between parties only takes place when data encrypted with the public key corresponds to the owner of a specific private ...

The appearance of Kabuki is attributed to Izumo Okuni a servant of the temple, which, according to the available documentary evidence, headed a predominantly female troupe that in 1603 staged presentation and light scenes (dance, comic sketches), choosing the parched bed of the Kamogawa River in Kyoto as their stage. Gradually, this company has gained national recognition and the plays by Okuni (and subsequently the entire genre) came to be defined by the term "Kabuki". Its basic meaning (literally – the technique of singing and dancing) was supplemented with a hint of "extraordinary" and "shocking" nature of the action. Kabuki ...

In Daniel Levitin’s TED Talk, “How to Stay Calm When You Know You’ll Be Stressed”, Levitin, a neuroscientist, gives sound recommendations on how to override the brain’s fight-or-flight mechanism, which regulates the brain’s secretion of cortisol and adrenaline into the bloodstream during times of distress. First, during his story, he recounts an episode where he lost the keys to his house, and rather than freeze outside, he lofted a brick through the window. As a neuroscientist, he realized (later) that the hippocampal structure of his brain remembers things spatially, due to our hunter/gatherer origins. Thus, ...

One of the most interesting facts that I learned from the academy was how patrolling worked. Before the academy, I was under the assumption that police officers randomly drove around neighbors to look for suspects and other criminal before. However, now I see that there is a define set of protocols that the officers are following when it comes to patrolling neighborhoods. For instance, there is a proactive and reactive approach when it comes to patrolling neighborhoods. Proactive is when the police officers are patrolling the neighborhood themselves to see if they can find any laws being broken or ...
