Database Normalization Is Important For The Future. Company Performance Information

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

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

A relational database is a database that consists of a collection of tables with columns showing entities, and rows showing data. This type of database uses a primary key and foreign key. The foreign key in another table will point to the primary key of a table, and this is how tables can relate to each other. This permits for one-to-one, one-to-many, and many-to-many relationship between the data. An advantage of relational databases includes the ease of adding or modifying new tables and entities without needing to change the structure of the database already in place. Relational database have many features, including indexing, setting data type, and setting validation tests, all these help to ensure data integrity.

The purpose of normalization is to create a stable set of relations is representative of the operations of an enterprise. By doing this we are able to reduce redundancy to save space and avoid inconsistencies in data. It also ensures that the design is free of certain updates, insertions, and deletion anomalies (Ricardo, 2012). With normalization as with most anything else there are advantages and disadvantages. The advantages of normalization are: ACID, which stands for atomicity, consistency, isolation, and durability. Atomicity means the transaction is a single unit. Either the entire set of actions is carried out or is not.

Hence, this session has enhanced my understanding about normalization and how essential to create a data that is well organized with the relationships clearly defined and established between the tables (based on the business rules) in order to eliminate data redundancy and inconsistency.

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]:

It is a design method that used to avoid data redundancy and eliminate uncoordinated relationship. Normalisation has six stages to help with separate data which are UNF, 1NF, 2NF, 3NF, BCNF, 4NF and 5NF.

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).

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.

One of the main functions of any business is to be able to use data to leverage a strategic competitive advantage. The use of relational databases is a necessity for contemporary organizations; however, data warehousing has become a strategic priority due to the enormous amounts of data that must be analyzed along with the varying sources from which data comes. Company gathers data by using Web analytics and operational systems, we must design a solution overview that incorporates data warehousing. The executive team needs to be clear about what data warehousing can provide the company.

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.

There are several important steps to consider when designing a database, as a well-designed database should be deployed and not only support the accuracy and integrity of business information but also avoid redundant data and assist with has enterprise level reporting tasked. If we analyze the

Normalizing the database will ultimately result in minimizing data redundancy and optimizing the data structures by containing smaller, more flexible tables. Once the tables are normalized and data integrity has been maximized, referential integrity will be addressed by establishing relationships between data elements and their appropriate groupings. Upgrading to SQL Server is a more viable alternative should Kudler Fine Foods' require a larger database capable of

An enterprise data model presents an abstraction of a more complicated real-world event or object. Generally, a data is graphical simple representation, of an interconnected real organization’s data structures. The main function of the data model is to help in understanding the complexities of a particular organization. A data model within a database environment brings out the data structures, their transformations, constraints, relations, and characteristics, thus providing a blueprint of

In every long term strategic planning, many companies considered data collection and analysis as a fundamental activity. Big companies that strive to achieve a sustainable advantage over their competition made use of information management system to help them analyze their data. These activities have evolved to what is now known as business intelligence of BI.
