Relational Database : A Database

Databases are the heart of the company. This is where all crucial company information is stored and can be accessed. Some databases are stored on site others in remote locations or using clouds. The information within a database can be manipulated in any way that the company needs it to be. Databases help to quickly search and retrieve information, it saves from data redundancy.

Be sure to provide a detailed explanation of relational databases along with their associated business advantages.

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.

General a database has a lot of tables and some tables are related to each other so relationship is use to make the connection between two or more tables. It is a method to avoid excessive data and to ensure the data integrity. There have three types of relationships:

Entities: Entities are objects that are located in a data base. Entities allow you to store data objects in the systems data base. These are set out in a table form in the data base. Primary keys, foreign keys, referential integrity and data redundancy are all part of entities.

The tables in relational databases organize data in rows and columns, simplifying data access and manipulation. It is easier for manager to understand the relational model than put all data in one table. Besides, a relational database allows tables to be linked. And the linkage reduces data redundancy and allows data to be organized more logically. In a word, relational database is easier to control, more flexible, and more intuitive than approaches.

A one-to-many database relationship is where each row in a table can be related to many other rows in another table. With being able to do this you can use frequently used data from one data and reference it many

Take inventory for example, Linton (n.d.) stated that “by using a database, you can replace manual methods of inventory control and reduce the time, cost and effort of inventory management” (para. 1). So basically, databases streamline the processes. When time is saved, productivity is increased. You can also look at this project to see how businesses utilize databases for their employee information. The forms that were created for this project show just how simplified inputting information has become. Almost everything is now in one database, and it can be shared across tables. It is the same concept for customer information.

Figure 11 shows the relationship of a database using DBMS, connecting the user with the information from the database. A database consists of many data from customers to orders, services, employees, and so on. The user can be a customer or employee. Employees use DBMS to find customer’s information, service types, and service provider information. Later in the process, the DBMS will then extract data from the database to answer the users’ questions.

I am utilizing the Relational Database in my proposal. According to Murthy, data in a relational database, is mainly represented in tables and is considered to be an assortment of relations. A relational database is similar to a spreadsheet, in that a relational database organizes data in tables. The table is then made up of rows and columns. A row is also known as a record or tuple, and a column is also known as called a field or attribute. Using a relational database allows me to efficiently store huge amount of data, and effectively retrieve selected data. Tables in the relational database are distinguished by a primary key, which confirms that “no

A database as documented according to "Dictionary.com" (2014), is a “systematized collection of data that can be accessed immediately and manipulated by a data-processing system for a specific purpose.” These collections of data are used to make searching for a needed product or service easy for a user. Each of these databases is comprised of a number of entities and attributes that are connected relationally to optimize the search for the best possible results. One such database is used by Booking.com. This is a database used for searching hotel rooms throughout the world. This database gives the user the

A quality database design makes the flow of data seamless. The database schema is the foundation of the relational database. The schema defines the tables, fields, relationships, views, indexes, and other elements. Envisioning the primary business function should facilitate creating the schema and how that information should flow throughout all areas of the firm. ("Strayer, iCampus," n.d., p. 1).

The main feature of a relation database would be the primary key. It is a unique identifier set to each and every record which moves across different tables in relationships. A good example of a primary key is a Social Security number. The primary keys job is to make each record unique and lets data to be kept in more than one table. Each table within a relational database will have to have a field for the primary key.

Firstly a relational database contains a set of tables which basically are linked collectively by the relationships between the tables. Also it is also known as reason such as a database is called relational database.

“A database is a structured collection of records or data that is stored in a computer system. In order for a database to be truly functional, it must not only store large amounts of record, but also be able to access those records fast and efficiently. In addition, new information and changes should also be easy to input.” (tech-faq.com) To be useful over a long term the database should be able to store all the records necessary for the business to function as well as be able to get all of this information back in case of a system failure or a crash. If all the information is loss a business could go bankrupt so the database is a fail
