As we all know Data is new Oil So in the upcoming era we all know that every business directly or in-directly depends on Data in multiple ways. But the data available at 1st stage is raw data or not so useful data. To make data meaningful we have to filter out the data in desired form according to usable form. So today’s topic of DIKW (Data Information Knowledge Wisdom) is based on the same concept. The DIKW Model describes how the data can be processed and transformed into desired information. DIKW is bifurcated into 2 differents groups: Contextual concept Understanding Perspective Contextual concepts involve gathering of data parts (data), the connection of raw data parts (information), formation of whole meaningful contents (knowledge) and conceptualizing and joining those whole meaningful contents (wisdom). From the the understanding perspective, the DIKW Pyramid can also be seen as a process starting with researching & absorbing, doing, interacting, and reflecting. DIKW seen in terms of time as well, in which the data, information, and knowledge levels can be seen as the past while the final step - wisdom - represents the future. Step 1 First step in this DIKW model is Data. Collection of data is that the primary requirement for reaching a meaningful end in the top . Any kind of measurements like logging, tracking, records etc are all considered as data. Raw data is collected both useful and not so useful. These are completely data and don't provide any meaningful result. Therefore the info doesn't answer any questions nor draw any conclusion. To understand how the Data is transformed into usable results using the DIKW Pyramid model, we will discuss each of the subsequent steps of the DIKW hierarchy (i.e. - information, knowledge, and wisdom) using sample scenarios. Step 2 Information can be termed as the data that has been given a meaning. Here, the word meaning represents processed / understandable data that may or may not be a useful piece of content from the organization perspective. In an information processing system, a relational database creates information from the data stored within it.The information hierarchy stage of DIKW Pyramid reveals the relationships in the data, and then the analysis is administered to seek out the solution to Who, What, When and Where questions. Step 3 Knowledge is the third level of the DIKW Model. Knowledge means the appropriate collection of information that can make it useful. Knowledge stage of the DIKW hierarchy is a deterministic process. When someone "memorizes" information due to its usefulness, then it can be said that they have accumulated knowledge.Every piece of knowledge itself has useful meanings, but it can't generate further knowledge on its own. In the information management system, most of the applications you use, such as modelling, simulation etc, exercise some sort of stored knowledge. The knowledge step tries to seek out the solution to the "How" question. Specific measures are acknowledged , and therefore the information derived within the previous step is employed to answer this question. Step 4 The Wisdom is that the fourth and therefore the last step of the DIKW Hierarchy. It is a process to urge the ultimate result by calculating through extrapolation of data . It considers the output from all the previous levels of DIKW Model and processes them through special sorts of human programming (such because the moral, ethical codes, etc.). Wisdom can be thought of as the process by which you can make a decision between the right and wrong, good and bad, or any improvement decisions. Alternatively, we can say that in the wisdom stage, the knowledge found in the previous stage is applied and implemented in practical life. Wisdom is the topmost level in the DIKW pyramid and answers the questions related to “Why”? Limitations of ITIL DIKW Model: The DIKW Model also has its own limits. DIKW Hierarchy is sort of linear and follows a logical sequence of steps to feature more aiming to data in every breakthrough . But the reality is different than that. The Knowledge stage, for instance , is practically quite just a next stage of data . Some other limitations of DIKW Pyramid is that it’s a hierarchical process and misses several important aspects of knowledge. In today's world, where we use various ways to capture and process more and more unstructured data, sometimes forces us to bypass a few steps of DIKW. Though the previous statement is sort of true, however, the result still stays an equivalent , like what we do with the info warehouse and reworking data through big data analytics into decisions and actions (Wisdom).
