Description

What is data preparation?

  • Data cleansing
  • Conversion of raw data before actual processing & analysis
  • Formatting data
  • Correction of information
  • Combination of data sets
  • Standardization of data formats
  • Elimination of outliers

Data preparation is often a longer-term task that can be very time-consuming and monotonous. Nevertheless, it is a very important step and prerequisite to establish a context between the data. Only if data are well prepared and allow correlations can insights be gained from them. With bad data or data that has not been prepared, one often cannot do anything or gets wrong information or impressions. That’s why data preparation is so important.

Why data preparation?

76 percent of Data Scientists think data preparation is the worst part of their job – but they also know that efficient, accurate business decisions can only be made based on clean data. Data preparation is therefore inevitable and elementary for every company.

Aim of the data cleansing

The goal of data cleansing is to find erroneous, duplicate, inconsistent, incorrectly formatted, or inaccurate and irrelevant data in a database and correct it.

Data preparation offers many advantages:

  • Efficient analyses
  • Reduced number of errors and inaccuracies during data processing
  • Generation of high quality data
  • Facilitates business decisions
  • It makes all processed data more easily accessible for users

Possible steps of data preparation:

1. collection of the data
First, the required data must be identified. These can come from an existing data catalog or be added ad hoc.

2. identification and evaluation of the data
Next, the data must be understood to understand and determine what actions are needed to make the data useful for a particular context.

3. cleaning and checking the data
Now incorrect data can be removed and gaps can be closed. This includes sub-steps such as:

  • Removing irrelevant data
  • Remove outliers
  • Adding missing values
  • Fitting the data to a standardized form

Often, these steps are followed by a re-check to ensure that the data preparation process has not caused any errors. Thus, it can be ensured here that the data quality is secured and complies with the specifications before further progress is made.

4. transformation and enrichment of the data
Transforming data is about updating the format or values entered to achieve a previously defined result, or making the data more understandable to a wider audience. Data enrichment involves adding data and connecting it with other related information to provide deeper insights.

5. storage of the data
After preparation, the data can be saved or imported into a third-party application. Now nothing stands in the way of efficient processing and analysis.

A domain is the address of a website.

A workflow is a work process. That is, a sequence of related steps performed one at a time. For your website, store or landing page, it can be a workflow like this:

  1. Visitor comes to your page
  2. Visitor signs up for your newsletter (by the way: now he is no longer a visitor, but an email subscriber)
  3. Subscriber receives a welcome email
  4. Subscriber will receive an email in the next 3 days with tips and prompts to buy your product
  5. etc.

The goal of a funnel is to turn a prospect into a valuable customer by going through multiple touchpoints to ultimately perform a specific action, such as completing an order.

Visually presented, Facebook ads, for example, attract many interested parties into the funnel. It can happen that interested parties jump off during the buying process, ie they jump out of the funnel again. However, the interested parties who have completed an order become customers and, figuratively, come out of the funnel at the bottom.

A landing page is a single page. Usually a website consists of several pages – a home page, contact page, about me or other pages. These are accessible via some kind of menu – usually a menu at the top that you can just click on.

A landing page, on the other hand, is a single page, usually without a menu and possibly deviating from the standard style. Because a landing page can be used to direct the entire focus to a webinar or to a product that you want to sell or to an event or, or, or.

So on a landing page, you want to direct the visitor to something, with their full 100% focus – without them getting distracted or being able to go elsewhere.
