Why data preparation is an important task

By Olga Papadimitriou – Sales Administrator

Data cleansing, transformation, and restructuring are all steps in the process of data preparation for analysis, business intelligence, and visualization. Putting data in context in the age of big data is frequently a time-consuming effort for data engineers or users, but it is crucial. Through this process, mistakes and bias brought on by bad data quality are removed and data are transformed into insights. A crucial phase in the data management process is data preparation, which can assist guarantee that data is correct, consistent, and prepared for modelling.

Data preparation tasks such as merging multiple data sources, splitting datasets, and transforming data can be complicated as it can involve a variety of tasks, like data cleaning (removing inaccurate or missing data), data transformation (changing data from one format to another), and data restructuring (aggregating data or creating new features). Although data preparation might be time-consuming, it is necessary for the development of precise predictive models.

The importance of data preparation

Preparing data takes up much of the time that data scientists have. Many data scientists feel that data preparation is the least enjoyable aspect of their work because of the amount of time they must spend on tedious activities, but reliable insights can only come from well-prepared data. Here are some of the main justifications for the significance of data preparation:

  • Delivers accurate analytics application findings
  • Encourages wiser decision-making
  • Decreases the cost of data management and analytics
  • Prevents redundant work
  • Increases the ROI of BI and analytics projects

Each business and engineer may have a different method for preparing data. However, the data preparation procedure consists of six basic steps:

1)      Data gathering

2)      Data profiling and discovery

3)      Data cleansing

4)      Data structuring

5)      Data enrichment and transformation

6)      Verifying and publishing data

Data preparation tips for businesses

When preparing data for diverse business use cases, keep in mind these six suggestions:

  1. Get ready for preparation. Make a schedule for who will finish which preparation tasks, on what schedule, and for what business objectives.
  2. Don't pretend that the data is flawless. Make sure you let stakeholders know if there are any data restrictions so you can adjust expectations as soon as feasible.
  3. While tools can be helpful, humans are still crucial. The inclusion of a human (with the necessary abilities) guarantees data quality, more accurate results, and gives the data context.
  4. To comprehend the distribution of your data, use hypothesis testing. You can perform several tests to gain a deeper understanding of the data and better prepare it for use.
  5. Set data priorities based on your use case. To prioritize data sources for a particular model, human judgment is necessary. The data preparation procedure can be streamlined by selecting which data sources will be used first.
  6. Consider data storage carefully. The pain of data preparation can be greatly reduced by standardizing data formats when data is being processed.
