Data Cleaning Is Important for Big Data Accuracy.

Data cleaning has been an integral part of data management and data analysis throughout history. This trend continues to grow rapidly. Data cleansing or data cleaning in Big Data is difficult because of the growing volume and velocity of data across multiple applications.

Because real-life data is often messy, it can prove costly. This is why data quality management is so important for businesses. Data cleansing is also known as data appending or data scrubbing. It involves correcting or removing incorrect data. Data cleansing is an important step. Bad data can cause poor business decisions. Bad Big Data has caused huge financial losses for some businesses.

What are the Different Types of Big Data?

Because big data comes from many sources, and can take many formats, it can be quite diverse. The data structure is important as it will determine how data will be stored, processed, analyzed, and retrieved. This is crucial for making raw data useful.

There are three types big data:

• Structured data
• Unstructured data
• Semi-structured data

Let’s take a closer glance at each of these big data types.

Structured Data

Structured data refers to data that has been stored within databases. These data can be stored and processed in a predetermined way. These data are the easiest type of big information because they don’t require any preparation. You can get structured data from either machines or humans. For example, customers signing up for new accounts will be given their name, address and age. You can think of structured data as the rows and columns you’d see in an Excel spreadsheet. Structured data only represents 20% of all available big data.

Unstructured Data

Structured data is, as its name suggests, the opposite of structured data. It is completely unorganized and doesn’t have a defined format. If it isn’t contextualized, unstructured data could be described as data without meaning. Twitter tweets, for instance, are just words. It doesn’t have any meaning or sentiment (before analysis). This holds true for an image you share or a call you make. These examples of unstructured data need to be placed in a real-world context for them to make sense. Because it uses complex algorithms such as those used in machine learning, AI, and natural language processing, unstructured data is more labor-intensive. Around 80% of global big-data is unstructured.

Semi-Structured Data

Semi-structured information refers to unstructured data with some organizational properties. This makes it more straightforward to process than unstructured information. Semi-structured data can have metadata attached, which is data that describes or gives details about another piece. It may also attach a timestamp to your smartphone and log your device ID. Even though the data is not structured, these additional details provide context for the image. Similar to the previous, if you email someone, even though it isn’t structured data, there are still “clues” such as the IP address or email address that it came from.

Annapolis, the capital of Maryland, is also the county seat and only incorporated municipality in Anne Arundel County. Annapolis is located on the Chesapeake Bay, at the mouth the Severn River, approximately 25 miles (40km) south of Baltimore, and 30 miles (50km) east of Washington, D. C. Annapolis is part of the Baltimore-Washington Metropolitan Area. Its population was 40,812, an increase in 6.3% from 2010.

History

The Confederation Congress was formerly called the Second Continental Congress. It served as temporary national capital from 1783-1784. General George Washington, who was then commander of the Continental Army, appeared before the newly constructed Maryland State House. The Congress ratified the Treaty of Paris of 1783 a month later. This ended the American Revolutionary War and gave the United States its independence. This was the location of the 1786 Annapolis Convention. It called on the states to send representatives to the Constitutional Convention in Philadelphia the next year. The Annapolis Peace Conference was held in 2007, more than 220 years after its original date.

Climate

Annapolis is located in the humid subtropical climate zone. It experiences hot, humid summers and cool winters. There is also plenty of precipitation all year. The area’s low elevation and close proximity to Chesapeake Bay make it more temperate in spring and summertime, and less cold than other locations farther inland like Washington, D. C.

Demographics

There were 40,812 residents as of the 2020 census. 49.4% of the population were non-Hispanic white, 21.7% African American and 0.7% Native American. 2.5% Asian, 14.5% other races and 8.1% came from more than one race. 22.9% of the population was Hispanic/Latino of any race.

Transportation

Annapolis is not served by any major highways. Interstate 595/U. is just outside the city boundaries. S. Route 50/U. S. Route 50/U. Interstate 97 connects with I-595/US 50/US 301 a few minutes west of Annapolis. This provides the best link to Baltimore. Maryland Route 2 passes outside of the city limits. It is the best link to Southern Maryland and also provides an alternative route to Baltimore.
