a.) Data administration
b.) Data dictionary
c.) Data normalization
d.) Data retrieval

Answers

Answer 1

Answer:

c.) Data normalization

Explanation:

Data normalization is the a process to organize tables in the database in such a way that data redundancy and anomalies (as a result of data manipulation) can be eliminated. So data normalization arranges the data in the form of tables, remove redundant data from the tables and eliminates duplicated data and also makes a large table into smaller tables. These small tables can then be associated to each other by making relationships between them. Data normalization also reduces the problems created by the data modification. These are often referred to as data anomalies e.g. insertion , deletion and update anomalies. Lets say a large table has redundant or repeated data. Without normalization the redundant data will take more space in the memory. Also it will not be easy to update data in such a table as it might result in data loss.3 basic types of database normalization forms are First normal form (1NF), Second normal form (2NF) and Third normal form (3NF). Others include Boyce-Codd Normal Form (BCNF) , Fourth Normal form etc.1NF states that columns of the tables which are also called attributes should have atomic values, 2NF form handles Partial Dependency and 3NF form handles Transitive Dependency.

Nadias Stage Fright Clark Benson Nadia sat at the piano, tapping her shoe to keep time with the rhythm of the song she had been practicing for a month. Her dog Lucky, her biggest fan, lay near her feet. At first, Nadia had to shoo him away and distract him with his favorite toy, a blue rubber ball. But now, Lucky had found the ideal spot on the floor; close enough to be near Nadia, but far enough away that he wouldnt disturb her playing.2Nadia had practically perfected this particular song, but she had to perform it at the school talent show and was relentless in her practicing. Before she started to play, she had a routine to prepare herself. First, she would stretch and wiggle her fingers to get them loose for playing. Then, she would take a few deep breaths to relax and clear her mind from the days activities. Finally, she would close her eyes and imagine herself playing the song; she envisioned her hands moving along the keys. After Nadia performed this routine, the song seemed to flow freely from her fingertips. Of course, she knew well enough that hours of practicing had resulted in her playing the song so well. Still, her routine allowed her to clear her mind and quiet the butterflies in her stomach.4Nadia knew those butterflies would be worse once she had to play the song in front of her entire school. When she decided to participate in the school talent show, she had chosen a more complicated piece of classical music. Nadia had been playing the piano since she was seven, and she truly wanted to challenge herself. When the big night finally arrived, Nadia prepared backstage. She watched her classmates display their own various talents. Then came the moment that both excited and terrified her; she was up next.6The audiences applause sounded like ocean waves and made her feel welcome. Still, she could feel those butterflies fluttering in her belly, and she felt her palms start to sweat. Nadia had already performed her routine backstage, but it seemed as if it hadnt worked this time! She sat down on the piano bench and looked at the black and white keys, which seemed unfamiliar now.7For a moment, she panicked and glanced at the audience in front of her. Nadia spotted her mother in the first row. Seeing her mother made her think of home and Lucky. This time, when she looked down at the piano keys, she imagined she was at home with Lucky beside her. In that moment, her nerves settled as she forgot about the audience eagerly awaiting her performance. Now that it was just her and Lucky, she struck the first note, and the other notes just fell in line with ease. When Nadia hit the last note, she turned to the audience and smiled. Just as she did, the audience erupted in applause.
