Data processing is an intermediary stage of work between data collection and
data analysis”- Explain the statement by enumerating the various operations
involved in it.
Answers
Answer:
Data processing occurs when data is collected and translated into usable information. Usually performed by a data scientist or team of data scientists, it is important for data processing to be done correctly as not to negatively affect the end product, or data output.
Data processing starts with data in its raw form and converts it into a more readable format (graphs, documents, etc.), giving it the form and context necessary to be interpreted by computers and utilized by employees throughout an organization.
Six stages of data processing
1. Data collection
Collecting data is the first step in data processing. Data is pulled from available sources, including data lakes and data warehouses. It is important that the data sources available are trustworthy and well-built so the data collected (and later used as information) is of the highest possible quality.
2. Data preparation
Once the data is collected, it then enters the data preparation stage. Data preparation, often referred to as “pre-processing” is the stage at which raw data is cleaned up and organized for the following stage of data processing. During preparation, raw data is diligently checked for any errors. The purpose of this step is to eliminate bad data (redundant, incomplete, or incorrect data) and begin to create high-quality data for the best business intelligence.
3. Data input
The clean data is then entered into its destination (perhaps a CRM like Salesforce or a data warehouse like Redshift), and translated into a language that it can understand. Data input is the first stage in which raw data begins to take the form of usable information.
4. Processing
During this stage, the data inputted to the computer in the previous stage is actually processed for interpretation. Processing is done using machine learning algorithms, though the process itself may vary slightly depending on the source of data being processed (data lakes, social networks, connected devices etc.) and its intended use (examining advertising patterns, medical diagnosis from connected devices, determining customer needs, etc.).
5. Data output/interpretation
The output/interpretation stage is the stage at which data is finally usable to non-data scientists. It is translated, readable, and often in the form of graphs, videos, images, plain text, etc.). Members of the company or institution can now begin to self-serve the data for their own data analytics projects.
6. Data storage
The final stage of data processing is storage. After all of the data is processed, it is then stored for future use. While some information may be put to use immediately, much of it will serve a purpose later on. Plus, properly stored data is a necessity for compliance with data protection legislation like GDPR. When data is properly stored, it can be quickly and easily accessed by members of the organization when needed.
Explanation:
Data is a collection of information, facts, findings, and figures of or about particular subjects.
EXPLANATION-
In the economy, data can be elaborated as the specific detailing on the piece of a topic of the organization, firm or any business entity. For example- A balance sheet of any firm is a fact of the financial statement but not the wholesome data but to the single specific terms. Data is distinguished between Primary and secondary data. Primary data is taken from the source point and is raw. Whereas, Secondary data is the molded form of data that has been used for a specific purpose. The data processing is the procedure between the accumulation of raw data and molding it into a specific manner that is ready to be used. Whereas the data collection and data analysis is the starting and end points of the process. The analysis is an end nature where the results of the two different data is put in effect to get to the final result that can help in decision making. Hence, all the 3 process are connecting dots to complete the cycle of the data and usage it into the desired manner.
