What Is Data Leaning?

Data Leaning is a concept in analytics that involves using data to identify and solve problems. The concept focuses on data that is incomplete, irrelevant or duplicate.

Duplicate records

Duplicate records can be a big problem when you are using data to make important business decisions. If you don't catch them, you may end up with inaccurate reports, which will negatively impact your writing. This can cost your business time and money.

There are many different types of duplicates. 

  • The first and most common form of duplicate data is a complete carbon copy of another record. These duplicates are the easiest to spot. However, if your database contains thousands of duplicates, you might not see all of them.
  • You may also experience partial duplicates, which are different parts of the same record, so check 550 informative speech topics for your life and studies. For example, a partial duplicate could have the same phone number and name.
  • These can be created accidentally, or by human error. For instance, when a web scraper scrapes two different pages, they may enter the same information into the same fields.
  • Data warehouses spend a lot of time and resources fixing errors. Moreover, they can't accurately identify missing values.

Irrelevant observations

If you are building a data mining application, there is a good chance that you will have to deal with a lot of redundant information. It's also possible to receive information from a variety of sources, such as data from multiple clients or departments. There is a need to remove the chaff from the wheat to get the best bang for your buck. 

This is where an advanced machine-learning tool can come in handy. By enabling your machine to monitor the performance of your algorithms in real time, you can avoid wasted effort.

In terms of data cleaning, the number one rule of thumb is to always validate your data using a dedicated software tool. One of the most important parts of data cleansing is deduplication. Fortunately, there are several tools to help you out.

One of the most useful is the 'no name' or 'no brand' software. These tools are especially helpful if you are collecting data from a range of sources. They can be invaluable if you are in the market for a new business venture, as they will ensure that your data is not compromised by a third party.

Incomplete data

Incomplete data has many possible causes. Some of these include human error, data entry, and machine errors. A good missing data strategy can help you identify and rectify these mistakes before they cost you the customer. There are many ways to go about this, but you need to select the right techniques. Choosing a suitable imputation method is paramount to successful missing data recovery.

The imputation method entails the collection of several data sets. These are then analyzed using standard statistical techniques. The main goal of this process is to come up with a single analysis result. Depending on the complexities of the data set, multiple imputation methods may be required. This is a worthwhile exercise for many reasons. Among other things, it allows a comparison of two or more competing data sets and provides a robust way of testing the statistical significance of one or more data sets.

It also demonstrates the importance of a thorough analysis of a complete data set. An appropriate missing data strategy should be applied to all data sets to ensure that your business does not suffer from the pitfalls of poor data collection practices.

Addressing outliers

The presence of outliers in data can ruin the process of estimating statistics. In addition to introducing bias into the results, they can also reduce the statistical significance of the data. Therefore, it is important to address outliers properly.

Outliers can be caused by a variety of factors. They can come from measurement errors, participant response errors, or objective factors such as process disturbances.

An outlier is defined as a value that deviates beyond the range of the majority of other data points. These values are generally more than two standard deviations from the mean. For example, a taxi company that has a zero ride record during a pandemic lockdown is an outlier.

Several methods have been developed to address the negative impact of outliers. One of these is called Expectation Maximization. It works by replacing outliers with a more moderate value. While this may decrease the variance, it will not alter the mean of the data.

Other methods involve binning the values. This method eliminates outliers that have a strong association with each other. However, this may not be the best approach.

What Is ETLT? Merging the Best of ETL and ELT Into a Single ETLT Data Integration Strategy

Data integration solutions typically advocate that one approach – either ETL or ELT – is better than the other. In reality, both ETL (extract, transform, load) and ELT (extract, load, transform) serve indispensable roles in the data integration space:

  • ETL is valuable when it comes to data quality, data security, and data compliance. It can also save money on data warehousing costs. However, ETL is slow when ingesting unstructured data, and it can lack flexibility.
  • ELT is fast when ingesting large amounts of raw, unstructured data. It also brings flexibility to your data integration and data analytics strategies. However, ELT sacrifices data quality, security, and compliance in many cases.

Because ETL and ELT present different strengths and weaknesses, many organizations are using a hybrid “ETLT” approach to get the best of both worlds. In this guide, we’ll help you understand the “why, what, and how” of ETLT, so you can determine if it’s right for your use-case.
