Discovery of Data
Discovery is the action of learning about information to form ideas about its potential applications. It’s the equivalent of checking the fridge for food before preparing dinner. During this phase, you may find problems like missing or incomplete values and underlying trends and patterns in the data. This is a crucial stage since it will shape the rest of the process.
Structuring of Data
Due to its incompleteness or improper format for the intended use, raw data is often useless before being processed. In data structuring, raw data is transformed into information that may be used more effectively. Your data will take on a specific shape based on the analytical framework you employ.
Cleaning of Data
Errors in the data can skew your analysis and reduce the quality of your results. Thus, it’s essential to clean your data before using it. Some examples of cleaning operations are the elimination of duplicates, the elimination of outliers, and the standardization of inputs. The purpose of data cleaning is to eliminate or reduce the number of mistakes that could affect the outcome of an analysis.
Enrichment of Data
Once you have a firm grasp of your data and have cleaned it up so that it can be used effectively, you will need to check to see if it contains all you need to complete your current endeavor. If that isn’t the case, you can select to “enrich” your data by adding in values from external sources. This is why it’s crucial to learn about the numerous use cases of data.
Validation of Data
If you want to make sure your data is reliable, you need to validate it. Validation is the process of checking whether or not your information is free of errors and, therefore, appropriate for analysis. Programming is often required for the many automated processes used in validation.
Publication of Data
Your data is ready for publication after verification has been completed. Sharing it internally for review is a necessary step in this process. Whether you choose to distribute the data in the form of a paper report or an electronic file will be determined by the specifics of the data you have collected and your company’s needs.
