Information About Data Cleaning

1. Variables in the Source Data

Removing outliers is part of data cleaning, data scrubbing, and data cleansing from NW Database ServicesData discovery is the process of identifying variables that are important in the source data. Then, you will need to determine what pre-processing steps need to be taken to make the data transform.

2. Plan the Data Transformation

You must determine the structure of the source data in order to map it to the landing system. We will convert the JSON data into a tabular format with rows and columns in our example. This step will allow you to decide whether fields should be renamed or dropped.

3. Perform the Data Transformation

Data transformation can be performed using a variety of tools and programming languages. Microsoft Excel, for example, is still a popular tool in data analytics. It has many functions and features that allow you to transform data within Excel. Python and SQL are two popular programming languages when it comes to data transformation. We’ll be using SQL in our example.

4. Analyzing the Data Transformation

After data transformation is complete, you should evaluate the results to ensure that they are accurate. You can use tools to verify that duplicates have been deleted or records have been counted.

3. A Sql Example of How to Transform Data

After we have reviewed the four-step process for transforming data, let’s now apply it to real data. Let’s transform JSON data into tabular using SQL. Over the past 40 years, SQL databases have been the most essential tools for data management. Understanding SQL is therefore crucial in data analytics.

Improved Data Quality

Data transformation pipeline removes duplicates, null value, and outliers. Also, we make sure that the data structure matches the destination system to ensure it can be accessed and queried in the same way. Data transformation does not only include cleaning and restructuring but also includes aggregating and feature-engineering. Data transformation can improve data quality and make modeling data easier.

Better Data Accessibility

Data analytics is difficult because data can’t be stored anywhere else. Data silos are a common problem in organizations. One database could contain customer data, while product event logs and sales data might be stored in another. Data transformation allows you to store all records in one location, in the same format.

Simpler Data Governance

Data can come from many sources, and can be stored in multiple places. This makes managing data difficult. To help organizations track which data is sensitive and regulate them, data transformation can be used. Good metadata makes it easier to manage data.

About Tennessee

Tennessee Information

Find Out About Tennessee

TennesseeTennessee is a landlocked country in the Southeastern United States. Tennessee is the 36th largest by area and 15th most populous state among the 50.


The Watauga Agreement, a 1772 frontier agreement generally considered to be the first constitution west of the Appalachian Mountains, is the root of Tennessee. Its name comes from Tanasi, a Cherokee settlement in the eastern portion of the state that existed prior to the arrival of European Americans.

Major Cities & Towns

Tennessee is divided into 95 counties. Each county has its own county seat. There are 340 municipalities total in Tennessee. Ten metropolitan areas are designated by the Office of Management and Budget in Tennessee. Four of these extend into neighboring states.


Although Tennessee is not close enough to the coast to be directly affected by a hurricane, it is still susceptible to remnants of tropical storms. These weaken over land and can cause heavy rainfall. Each year, the state experiences 50 days of severe thunderstorms. These can cause large hailstones and dangerous winds. All parts of the state are susceptible to tornadoes, but West Tennessee and Middle Tennessee are the most at risk. On average, the state experiences 15 tornadoes per year. These can be deadly and the state is the leader in fatalities from tornadoes. Winter storms like those of 2021 and 1993 are not uncommon, but ice storms are quite common. Fog is a problem in certain areas, particularly East Tennessee.


Tennessee’s population was 6,910,840 according to the 2020 United States Census. This is an 8.90% increase over the 2010 census. The state experienced a natural increase in population of 143,253 between 2010 and 2019. This includes 744,274 deaths and 601,021 births, as well as an increase due to net migration of 338.428 people into the state. The net result of immigration from the U.S. was a net gain of 79,086, while the net effect of migration within the country was a net gain of 259,342. Tennessee’s population center is located in Murfreesboro, Rutherford County.


Tennessee’s gross state product was $418.3 million as of 2021. The state’s per-capita personal income was $30,000. Median household income was $54,833. The poverty line was 13.6% of the population. The state had a total employment rate of 2,724,545 in 2019 and 139,760 employers. Like most of its Southern neighbours, Tennessee is a right to work state. As in many other U.S. states, unionization has been historically low and continues to decline.
