Normalization Process Within A Database

Step 2. Data Analysis: The data will be analyzed to determine database modeling. Step 3. Database normalization: Fields and

Well-organized file names and folder structures make it easier to find and keep track of data files. A system needs to be practical and used consistently. Without organization, you cannot report data effectively.

Identify the different types of entities, attributes, keys and relationships you will want to consider when designing the database.

* Write clearly and concisely about relational database management systems using proper writing mechanics and technical style conventions.

There are three stages to normalization, 1st NF, 2nd NF, and 3rd NF. In the 1st NF stage must ensure that the table has no multivalued attributes. If there are the table should be broken down into separate tables so that there are no multivalued attributes. The 2nd NF stage requires that we break the tables down even more to ensure that all attributes and functional dependency entirely to the primary key and has met all requirements of the 1st NF. Then, and only then will it be considered to have met 2nd NF requirements. To transform the database to 3rd NF you must identify the primary key in the 2nd NF table. Then we must identify functional dependencies in the relationship to ensure there are no transitive dependencies. These types of dependencies can cause insertion, deletion, and update

My thoughts on normalization is that it requires multi-steps to enter the data into tabular format to ensure they are well-organized in a way that is consistent and lacks redundancy as well as prevent unintended or unambiguous results. As stated by Demba (2013) that normalization in relational database design often involves the process of organizing data and dividing the database into two or more tables with defined relationships in order to minimize

This step includes the task of describing a subset of data for each type of user based on his/her privileges and requirements. This is done to ensure that no additional information is given to the user. Views provide a level of abstraction to the database.

Normalization for entity-relationship modelling works as it does for other modelling systems, with some alterations. [13] The difference when using the entity-relationship data model is [14]:

First our team will talk about how Microsoft Access was used to create these tables by Huffman Trucking Database. Then how we used the tables with made up information to be tested on. Then on how we used forms in the maintenance database system. While the creation of relationships and normalization is explained in the process of using queries to search the database (University of Phoenix, 2007).

Normalization gives the equal importance to all the variables in terms of variability. As we selected the correlation matrix in the step 2 in the PCA component analysis, so the data is first normalized. The dataset is normalized by subtracting the

A well-designed database should be able to provide accurate information on-demand, especially if your data is subjected to frequent changes or updates. For this reason, carefully organizing data as structured content in your database is a critical process. One way to do this is through data normalization.

Operational systems are optimized for preservation of data integrity and speed of recording of business transactions through use of database normalization and an entity-relationship model. Operational system designers generally follow the Codd rules of database normalization in order to ensure data integrity. Relational databases are efficient at managing the relationships between these tables. The databases have very fast insert/update performance because only a small amount of data in those tables is affected each time a transaction is processed. Finally, in order to improve performance, older data are usually periodically purged from operational systems.

Data management is vital to any business as this is a key tool to an organisations business improvement, as you can refer back to data, and compare them against benchmarks. Analysing data can provide evidence for possible future structure such as identify trends, as well as indicate where improvements can be made. However there are strict procedures to be followed when collecting and storing data.

Normalizing is a technique used to help clients see life’s experiences as normal or common. When the therapist uses this technique, the client feels that if others can handle the situation maybe the client can as well. I reviewed the interview, but did not see any type of normalizing used. I think that if the situation were different, normalizing would be a tool I could use productively.

Normalization refers to the focus, concentration and independence of the child, by his own choice. It means the child has acquired the internal freedom to initiate work, be independent, and adhere (by choice) to the rules of the environment.
