Related: What Is a Data Scientist? Data manipulation is important to ensure companies can access the information they need to make business decisions. This process makes it easy for them to tailor data to meet their specific needs or focuses.
The way they manipulate data may change over time along with business changes. This flexibility offered by data manipulation is important for companies to continue growing and learning from their analytics. Another reason manipulating data is important is because it can help companies boost their efficiency because they can easily identify and eliminate redundancies.
Companies may manipulate data to transform it into useful insights that they can use for stakeholder presentations, project or financial decisions and trend or success measurements. Here are four reasons companies may choose to implement this:. Companies may manipulate their data because it can provide them with well-organized databases. Categorization can allow companies to group data with similar data, which may make it easier to search for information.
For example, a company may choose to manipulate its data in an alphabetical organization. Then, if they need to access specific data, they know exactly where to find what they need.
Depending on preference, businesses might categorize data in a variety of different ways. Another reason companies might manipulate their data is because it can provide them with insightful access to data and information about their projects. This can allow them to archive project data and access it later if they want to use it as a reference while working on a new project or setting business goals.
Businesses may also reference their previous data when examining finances and whether profits are increasing. Companies that choose to manipulate their data can do more with their data and personalize it to meet their specific business needs. This is because they can tailor data to work within databases and provide specific insights. For example, if a business were interested in learning more about its website traffic and specifically wanted to know how many visitors visited over two pages, they might manipulate their website traffic data to provide those results.
Then they can use this data to help make informed website decisions. Companies that choose to manipulate their data might also avoid unnecessary data. Isha Upadhyay 10 Dec Introduction Regardless of the industry, knowledge affects the way organizations work. What is Data Manipulation? Data Manipulation Examples Data Manipulation is the modification of information to make it easier to read or more structured. Purpose of Data Manipulation For business operations and optimization, data manipulation is a key feature.
As such, data manipulation provides an organization with many advantages, including: Consistent data: It can be structured, read, and better understood by providing data in a consistent format. You may not have a unified view when taking data from various sources, but with data manipulation and commands, you can make sure that the data is structured and stored consistently.
Project data: it is paramount for organizations to be able to use historical data to project the future and to provide more in-depth analysis, especially when it comes to finances. Manipulation of data makes it possible for this purpose. Overall, being able to convert, update, delete, and incorporate data into a database means you can do more with the data. It becomes pointless by providing data that remains static.
But you will have straightforward insights to make better business decisions when you know how to use data to your advantage. Delete or neglect redundant data: data that is unusable is always present and can interfere with what matters.
A Contrasted with language programming It looks very stilted when you first look at Data Manipulation Language. Steps Involved in Data Manipulation When you want to get started with data manipulation, here are the steps you should take into consideration: Only if you have data to do so is data manipulation feasible.
You need a database, therefore, which is generated from data sources. This knowledge requires reorganization and restructuring. Manipulation of data helps you to cleanse your information.
You know what findings interfere or are redundant, what metrics have a low or significant impact. Being able to identify and isolate those elements quickly is made possible through DML. It is also important to note that we see data manipulation in action daily. If you are receiving emails, getting targeted adds on the websites you browse, or if you are receiving calls from telemarketers, it is because of data manipulation. Your online behavior is also turned into data, and thanks to quality data manipulation, relevant information can be extracted.
Once you share your email address at a particular site and agree to their terms and conditions, you are likely to consent to behavior monitoring that is used to generate relevant data. In other words, data manipulation is pretty much how the world functions nowadays, and it's the reason why your online experience is vastly different than the one you had 20 years ago.
Now that we covered data manipulation, we should also talk about data modification. Although these two terms sound similar, they are not interchangeable. Generally speaking, data manipulation is the act of processing raw data with the use of logic or calculation to get a different and more refined data. Data modification, on the other hand, means that you are changing the existing data values or data itself.
That would be an example of different ways how we can read the given value using logic. Now, how do we use data modification with data manipulation to aid business decisions? Well, if data manipulation is used to process multiple data sources, data modification can be used for calculating financial goals, for example. Now that we covered how things work in theory, let's see what you can do with this in practice. As Microsoft Excel is one of the commonly used tools for data manipulation, we can go over some of the tips that work on this tool.
This for example happens to a lot of historians. It is a well-known fact that historians around the world have been for hundreds of years trying to come up with the ideal theory of history which would help us predict the future of humanity and understand its past. Probably the guiltiest of fact fitting are some Marxist philosophers of the twentieth century who had a quite simple view of history as a repetitive process which led them to say quite fascinating things.
Check the facts. That is actually important in a lot of cases. If a scientific fact is actually a scientific fact then it probably comes up in more than one publication.
Apply the rule of big numbers — if something like that would actually be true — would you be the first one to discover it? This applies to scientific studies too. A shocking new discovery? Why has it not been done before — time to go over all the previous points and check the research. These three are points do not cover everything concerning data manipulation and statistic misuse but they do provide the most important tools to be able to detect them in a field of which one has at least a basic comprehension.
Part two: LaCour and scientifically based data manipulation. There are unique situations when data is not just manipulated, but manipulated professionally. Fact are pushed in different ways by a person who knows what he is doing — an easy example to see this in work is any political debate.
It a case that happened in the years and has rocked the scientific world. It was a large scale poll with ten thousands of respondents. All previous results in similar works had shown that people hardly change their political and social views. He wanted to conduct similar experiments. This was his first hint.
He did not come out with it because it is easy to gain the reputation of someone who does no work of his own and just tries to ruin others work. A lot of people — scientists, researchers who Broockman talked to told him not to publish such materials. LaCour lost his just obtained position in Princeton and his reputation — it will now be really hard for him to return into the world of science.
