There are three primary types of big data: structured, unstructured, and semi-structured.
1. Structured Data: This type of data is organized in a specific format that allows for easy filtering and sorting, such as rows and columns in spreadsheets or databases. Examples include customer records, financial transactions, personnel information systems and more.
2. Unstructured Data: This type of data lacks design or pre-defined structure; it’s usually natural language text like documents, emails, images or audio files. Examples include social media content (videos/posts), customer feedback surveys/reviews and call centre recordings.
3. Semi-Structured Data: This type of data falls between structured and unstructured; it has components that are organized but not necessarily following any specific predefined structure – such as XML documents or JSON objects typically used in web applications . Examples include sensor readings from the internet of things (IoT) devices or log files from server logs generated by services like Google Maps or YouTube .
1. Structured Data: This type of data is organized according to pre-defined models such as databases, flat files, and spreadsheets. Structured data makes it easier to process and analyze the data since they have an established format.
2. Unstructured Data: This type of data is not organized according to a specific model or schema and cannot be easily integrated into traditional databases or programming languages. Examples include web logs, social media posts, images, videos, emails and text documents among others.
3. Semi-Structured Data: Also known as ‘meshed’ or ‘hybrid’ data structure, semi-structured data contains elements of both structured and unstructured forms of big data; meaning that there may be some organization present but it is not as rigid as with structured formats like tables/databases or XML documents. Examples include JSON (JavaScript Object Notation), CSV (Comma Separated Values) files etc..
4. Multimedia Data: Multimedia Big Data refers to digital audio/video recordings containing vast amounts information which require powerful systems for real time analysis in order to extract valuable insights from them (e.g.: facial recognition).
Big data can generally be divided into three types: Structured data, Unstructured data, and Semi-Structured data.
Structured Data refers to information that is organized in a specific way, typically using rows and columns (e.g., tables). It’s easy for computers to process this type of data because it follows fixed formats and pre-defined schemas. Examples of structured data include customer transaction records from e-commerce sites as well as health records from hospitals.
Unstructured Data refers to information that does not have any predefined structure or organization. This includes all the text, images and videos we produce on our smartphones or the web every day. Unstructured data cannot be easily processed by traditional computing systems because there are no set rules governing how it should be organized. Text analytics tools, natural language processing algorithms and AI trained models are needed to make sense of unstructured big data sets.
Semi-Structured Data lies between structured and unstructured bigdata; it has some kind of inherent structure but not a fully defined one like relational databases follow. Examples include JSON files generated by social media sites, XML documents produced by content management systems (CMS), log files containing server access information connected with web applications etc.. Log files usually contain time stamps along with other details of users’ actions so they have some organizational logic built into them which makes semi-structuring possible without having too much expertise in the domain knowledge required for creating relational database schemas from scratch.
Big data can be divided into three different types based on the amount of size, velocity and variety.
1. Structured Data: This type of data is organized in a structured way, usually in rows and columns with field names that define each column’s content. This data is easier to analyze since it follows specific guidelines making it easier to query. Examples include credit card records and customer databases stored in relational databases like MySQL or Oracle.
2. Semi-structured Data: Semi-structured data does not follow a specified format but contains tags or other markers to separate fields within the data structure. Examples include JSON, XML files, log files from various sources such as web servers and email services which are highly unstructured yet contain useful information for analysis tasks like customer behavior evaluation or network security threats assessment.
3 Unstructured Data: Unstructured data does not possess any pre-defined format that allows machines to easily parse through the content for analysis purposes; instead, it requires specialized tools for interpretation such as text processing or natural language processing algorithms along with knowledge engineering techniques when applicable (especially when dealing with medical & legal documents). Examples include audio recordings, images & videos captured by cameras/sensors, emails containing multimedia attachments etc…
