Recommended: The purpose of database management system
Data is a collection where the information has been stored in the system. It’s also is a raw material that generate by the information. Data can be forms in variety of types such as audio, images, listing, mind mapping, hierarchy, text documentation and any types that form data. It can be value either in a qualitative or quantitative depends through its information requirement. Computers will organise the data that consists of raw numbers to produce an information. Computers represents data through numbers either the data come in form of images, numbers, text, and also sound all this are will be seen by a computes as a number.
One of the characteristics of a data is globally used. Due to data are easily to use through world wide range. This is because, data is a simplest form that easily be understood by people once they know how to read the data and what are the data is about. For example, in a lecture process most lecturer will use point form to present their topic and the details of the point will be elaborate on that time due to their way. This way are easy to be accept because human mind are attracted by the simplest and compact form. Data is something that created to simplify the information to the simplest form that can be understand by the people by seeing the data. For example a table. A table that consist of name, address, telephone number and gender. All the details inside the table are called as data. Which means the data would be understand by seeing through the table.
Secondly is all data consists of object attributes which means, each data have their own personalization. It depends on their characteristics to make sure that users can understand the information that want to be deliver according to the data prese...

...e problem. This can be done by find any information that consider might help the lecturer to give an idea toward the good delivery process. This information that can help the lecturer is valuable because it is a way to solve the problem. But the result still remain unchanged, technical way has to be taken.
Information also known as a knowledge communication in a particular fact or information that concern in a crime. Other than that, knowledge can be gain through studying, researching and communication that can be as information if we able to clarify and differentiate the information based from all those thing through their perception.

Chapter one is an examination of different definitions of ‘information’ to support the concept of ‘informa...
There is no concrete definition of knowledge, but there is a definition that is widely agreed upon, or a standard definition. This definition may be widely accepted, but just like most things in philosophy, it is controversial and many disagree with it. The definition involves three conditions that must be met in order for one to truly say that they know something to be true. If one were to state: “The Seattle Mariners have never won a world series,” using the standard definition would look like this: first, the person believes the statement to be true. Second, the statement is in fact true. Third, the person is justified in believing the statement to be true. The three conditions are belief, truth, and justification. There are the “necessary and sufficient conditions” for knowledge. Necessary and sufficient conditions are linked to conditional statements, ‘if x, then y’ statements.
Tabular Collection Diagram shows the process of the system, so it helps identify risks or problems in a system early on. Tabular Collection Diagram put requirements to the test and enables you to see if more requirements are desirable. A brilliant method to discover problem’s in the earlier stages of development.
Knowledge according to Merriam- Webster’s dictionary is “acts, information, and skills acquired by a person through experience or education.” Rene Descartes saw knowledge being attained through deductive logic and would disagree with this definition. Charles Peirce’s pragmatic approach on the other hand is the reason we have that definition.
A database is a structured collection of data. Data refers to the characteristics of people, things, and events. Oracle stores each data item in its own field. For example, a person's first name, date of birth, and their postal code are each stored in separate fields. The name of a field usually reflects...
Knowledge is the key to more information that can really stand you out from the rest. This can cause problems for people who crave the unknown or want more than what is given for self-benefit. Books and the internet can only do so much for us to increase technology or even increase work ethics, but in the bad side knowledge can lead up to using the information for terror or etc. The amount of information in this world is a double-edged knife for having it's good and bad to oneself and society and an example of this happening is in Mary Shelley’s novel Frankenstein.
There is really a need for applications to handle very complex data and that is why the interest of people in building such systems is...
Communication is a process where information is shared by two or more persons and has relevance for at least one of the persons involved. Further, communication implies that individuals
Currently the world has a wealth of data, stored all over the planet (the Internet and Web are prime examples), but it is needed to be understand that data. It has been stated that the amount of data doubles approximately
According to Merriam-Webster Dictionary (n.d.) data is defined as factual information used for discussion, scientific research and analysis. Information is defined as having the capability of communicating knowledge that is being presented to increase or explain a problem or a solution to a particular matter (Merriam- Webster Dictionary, n.d.). According to Oxford English Dictionary (n.d.) knowledge is defined as having the ability to recollect information that is gained through personal experiences, experiences from others or education. Wisdom is defined as having the ability to make practical decisions from previous experiences or knowledge (Oxford English Dictionary, n.d.).
Information Retrieval is simply a field concerned with organizing information. In other terms, IR is emphasizing the range of different materials that need to be searched. Others researcher said that IR is the contrast between the strong structure and typing a database system with the lack of structure in the objects typically searched in IR. The actual process in information retrieval systems is it has to deal with incomplete or under specified information in the form of the queries issued by users. IR uses the techniques of storing and recovering and often disseminating recorded data especially through the use of a computerized system.
Big data will then be defined as large collections of complex data which can either be structured or unstructured. Big data is difficult to notate and process due to its size and raw nature. The nature of this data makes it important for analyses of information or business functions and it creates value. According to Manyika, Chui et al. (2011: 1), “Big data is not defined by its capacity in terms of terabytes but it’s assumed that as technology progresses, the size of datasets that are considered as big data will increase”.
The general concept of ‘information’ is used in a confused manner. By some it is seen as something we distil from data in order to make decisions, and to a point this could be a true observation. By others it is seen in terms of the understanding that we gain from messages or the knowledge that one person communicates to another and the meanings we create and exchange.
Variety: Organizations collects variety of data in several ways. Data which are collects by using internally or externally can be structured, semi-structured or unstructured. As a example social media sources, such as face book, blogs and tweets and data coming from sensors can be semi structured or unstructured. This variety of unstructured data creates problems for storage and analyzing data.[5]
The database application design can be improved in a number of ways as described below:
