Relationship Between Data And Information – Data, information and knowledge are often used interchangeably. However, these terms refer to different stages of value creation from data to decision making.
Data are raw alphanumeric values obtained using different acquisition methods. In its simplest form, data consists of raw alphanumeric values.
Relationship Between Data And Information
Information is created when data is processed, organized or structured to provide context and meaning. Information is essentially processed data.

Knowledge is what we know. Knowledge is unique to each individual and is the accumulation of past experience and insight that forms the lens through which we interpret information and give it meaning. For knowledge to lead to action, a person must have the authority and ability to make and implement a decision. Knowledge (and authority) is necessary to obtain actionable information that can make an impact.
The flow and characteristics of these terms are shown in Figure 1 and Table 1. Table 2 shows examples of water data data, information and knowledge.
The flow of data to information and knowledge is not unidirectional. The knowledge gained can reveal redundancies or gaps in the collected data. Therefore, it may be useful to change the data collected or how that data is transformed into information to better meet the needs of users. Relationship between data, information and knowledge. Candidates should understand that: Data consists of raw facts and figures, e.g. sensor readings information is data that has been processed by a computer system, knowledge is derived from information by applying rules from a specification to it
Raw facts and figures before processing. By themselves they have no meaning. e.g. sensor readings, test results, research facts Information Data that has been processed (arranged, sorted, formatted, calculated) by a computer system. It is put into a context that makes it meaningful. Knowledge is derived from information by applying rules to it in order to understand or interpret it. Knowledge is used in decision-making.

Example 1 Data: 1, 12, 1.4, 2, 12, 1.2, 3, 16, 1.1 Information: swimming times 100 m swimmer without age group Time (min.) 1 12 1.4 2 1, 2 3 16 1,1 Knowledge: the swimmer is not the 2nd fastest in the 12-year-old group. Data is processed to become information. Information is subject to rules and becomes knowledge
This set of numbers is the data that represents the student’s test results. (By themselves, they are meaningless because they have no context.) Information: The data has been processed and given context. Now that’s meaningful information. Jon Ward’s Scores Test 1 Test 2 Test 3 Raw Score 20 25 30 Max Score 50 100 Percent 100% 50% 30% Knowledge The teacher sees that Jon’s scores show a downward trend. The teacher uses the 40% pass rule to find that John passed tests 1 and 2 and failed test 3.
A list of numbers representing product codes and quantities sold this month. Information The data is grouped by branches, the paid out amounts are calculated and added up. The processed information is added to the Monthly Branch Sales Report (context) and formatted (currency format) for the manager.

After further processing of the additional data, the teacher decided that none of the boys deserved an end-of-year prize for good work. Question 2. Can you explain why she might make this decision?
Reasons for coding data and problems related to coding. Candidates should understand why data is encoded and the potential problems associated with this, especially when evaluating values. from the specification
Speeds up data entry because the codes are short and the user can click to select a code from a list. Reduces the chance of data entry errors as less input is required. Codes are shorter than raw data, saving disk space. Disadvantages Defines data by placing them into a small number of groups (categories). The value judgments required to fit the data into a certain group (category) may therefore be inconsistent in the selection of categories by data entry personnel.
Department heads evaluate each employee’s attendance over 345 days a year. The data entry form allows you to choose from only 4 categories: excellent, very good, good, unsatisfactory. Different managers may categorize equally attended employees into different categories because of their values. Employees with widely varying attendance may be assigned to the same category because there are not enough categories to make a precise determination. “Unsatisfactory” can mean I spend a day less than “good” or 200 days less, as the category can cover a wide spectrum of attendance.

Information management is a key part of good corporate governance. Its mission is to maximize the value of information while minimizing the cost and risk of its storage. Data management is a key subset of this model. It aims to control information at the data level, ensuring that accurate and high-quality data is maintained through the implementation of relevant systems and processes.
This article discusses the roles of information management and data management in an organization and how they are interrelated.

Information governance provides a strategic framework for organizations seeking to control corporate information. It recognizes the value and opportunities of data as the “new oil” and identifies the risks and costs associated with non-compliance with legal requirements and the consequences of a serious data breach.
Information governance is defined by the Information Governance Initiative (think tank and IG professional community) as follows:
“The activities and technologies that organizations use to maximize the value of their information while minimizing the associated risks and costs.”
In other words, information governance includes the systems (including policies, processes and technologies) by which information is managed and stored.
Pdf) Defining Terms: Data, Information And Knowledge
Organizations should view information as an asset and assess the value and cost of the data they hold. This means quantifying the financial benefits of data, as well as the costs (and subsequent cost savings) of risk management investments.
To benefit from information, companies must invest in technology and systems that can be used to gain a competitive advantage and deliver benefits directly to the bottom line. This includes implementing data analytics to improve or develop new services or products, or data sharing systems to improve, for example, the allocation of resources to the provision of health services in the public sector.
Reducing the risk and cost of information storage is one of the main goals of an information management program. Achieving this requires additional strategic investments, particularly in technology, systems and people.
Organizations incur significant costs for information required to conduct business (RIM) and/or by law. Legal requirements include:
Paper Example On Relationship Between Data, Information, And Knowledge
Well-managed organizations have an active defensible records disposition program that removes documents no longer required by law and regulates the ongoing removal of redundant, obsolete and irrelevant (ROT) documents from the business.
Reducing data storage costs can be counterproductive by encouraging data retention. Storing large amounts of data can be a significant financial burden, especially when you consider the following:
An effective information governance program can also help reduce the costs of a serious data breach, including:
Data management is a major subset of information management. Its purpose is to control data at the data level and ensure integrity through appropriate systems and processes.
What Is Information Systems? Definition, Uses, And Examples
“Data governance is a system of decision rights and accountability for information-related processes, implemented according to agreed models that determine who can take what actions with what information, when, under what circumstances and by what methods.
“Data Governance (DG) is a subdomain of Information Governance (IG) that involves the design and execution of data requirements planning and data quality assurance in conjunction with the organization’s strategic information needs. Data governance includes data modeling, data mapping, data auditing, data quality control, data quality management, data architecture, and data vocabularies. DG collaborates with Enterprise Information Management (EIM) on the functional components necessary for enterprise information organization and plans.
