Fundamentals On Database Management Systems

Data objects can model relational data or advanced data types such as graphics, movies, and audio. Smalltalk, C++, Java, and others are objects used in object-oriented data. The object-relational is a combination of relational and object-oriented databases. Traditional and advanced data types can be used to construct database management systems. These systems can connect to a company’s website and update records as needed. Database Approach The main purpose of a database is data storage that can be stored and retrieved when needed. A popular common language called structured query language (SQL) is used to store and retrieve data in relational database. This language enables the systems to run a report or modify data or remove the data from the database. A database management system (DBMS) controls all aspects of a database, this is not limited to the creation, maintenance, and use of database. The DBMS ensures proper applications are able to access the database. An important purpose of a DBMS is to maintain the data definitions (data dictionary) for all the data elements in the database. It also enforces data integrity and security measures. Data Models Data models provide a contextual framework and graphical representation that aid in the definition of data elements. In a relational database, the data model lays the foundation for the database and identifies important entities,

A database administration framework (DBMS) is a PC programming application that connects with the client, different applications, and the database itself to catch and dissect information. A universally useful DBMS is intended to permit the definition, creation, questioning, upgrade, and organization of databases.

Databases today are essential to every business. Whenever you visit a major Web site – Google, Yahoo!, Amazon.com, or thousands of smaller sites that provide information – there is a database behind the scenes serving up the information you request (Hector, Ullman, & Widom 2008). Database systems are becoming as common in the workplace as the essential one that it can easily be searched, categorized and recalled in different means that can be easily read and understood by the end user.

This must be in your own words and not copied and pasted from the original source. Include the purpose of the database and the subject matter it covers. This may be four or five sentences; and

Database, it is a place use to store lots of data. It can be seen as a filing cabinet. And database management system (DBMS) is software that specificity designs for managing the data in database such as create, update or delete them. General is including security, retrieval and backup features. User also allows using the data to create a report or share data with multi-user.

Database systems provide efficient access to large volumes of data and are vital to the operation of many organizations.

A database is part of a larger system known as an information system, it helps with the collection, storage and retrieval of data. The database structure needs to be defined and its fields labeled properly for it to be an asset to the user.

As you recall, data is a collection of facts (numbers, text, even audio and video files) that is processed into usable information. Much like a spreadsheet, a database is a collection of such facts that you can then slice and dice in various ways to extract information or make decisions. However, the advantage and primary use of a database over a spreadsheet is its ability to handle a large volume of data and yet allow for quick access to the information that is desired.

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.

Relational database contains data records that do not have a preset of relationships, permitting the user to define his or her relationship when accessing the data. Since users have much control over the data being accessed, relational databases can perform a variety of tasks. Such as defining the database; querying the database; adding, editing, and deleting data from the database; modifying the structure of the database; securing data from public access; communicating within the network; and exporting and importing data (Murthy, 2008).

There is a thing called a database management system also known as DBMS, which are supposed to use software that is specifically designed to interact with other software applications as well as the user and the database to help analyze and capture data as it comes in. There is a general-purpose database management system, which actually allows databases to be created, updated, defined as well as query and be

Databases are normally used by businesses and schools to store their data. These databases are kept secure, and users can only access the information stored on the database they have been granted access to. Now data is added to, accessed, or remove from a database using languages such as SQL (Structured Query Language), MYSQL (My Sequel), etc.

1. What are data, information and knowledge? Provide an example of transformation of data to knowledge using as an example the Accounts Receivable (AC) in the accounting department or personnel data in the HR department.

Databases allow us to easily store and retrieve data in a purely digital format. The strength of this is that large amounts of data can be stored and retrieved with minimal effort on the part of the user. Opposed to manually flipping through files, one can quickly pull up the requested data through a computer program. Many systems that were conventionally paper and file based have been converted to a digital format which are now stored in one or more databases.
