What is Blob and Which type of data stored in blob.

Storing and retrieving large amounts of unstructured data, such as text or binary data. It is part of the Azure Storage service, which also includes services like Azure Table Storage, Azure Queue Storage, and Azure File Storage.

I would say refer to MS docs for complete details and try it out ceating one.

A Blob (Binary Large Object) is a collection of binary data stored as a single entity in a database or within a file system. Blobs are typically used to store large amounts of unstructured data, such as images, videos, audio files, documents (e.g., PDFs, Word documents,Images), and other multimedia formats.

I asked ChatGPT What is Blob and Which type of data stored in blob and the response from it was:

In computing, the term "blob" stands for Binary Large Object. It refers to a data type used to store binary data, typically large files or objects, in a database or storage system. Blobs are designed to hold various types of data, such as images, videos, audio files, documents, or any other binary data that cannot be directly interpreted as text.

Blobs are commonly used in database management systems to efficiently store and retrieve large amounts of binary data. They provide a way to store unstructured data in a structured database environment. Blobs are often represented as a collection of binary data bytes, without any specific format or structure imposed by the database system.

By using blobs, applications can store and manage files or binary data within a database, making it easier to organize and retrieve the data when needed. For example, a web application might use a blob to store user-uploaded images or a document management system may use blobs to store files and attachments.

In summary, blobs are a type of data storage mechanism used for handling binary data, allowing for the efficient storage and retrieval of large files or objects within a database or storage system.

see, you can think of blob as any large single block of data such as a picture or sound file in binary format etc. I know you are confused with azure blob storage.

As the name suggests, azure blob storage is nothing but a space to store large unstructured data like files or any other binary data, which we call as blob and the path of that storage file you can store in a database like in a normal varchar column.

In the context of computer science and databases, a Blob (Binary Large Object) is a data type used to store large binary data, such as images, audio or video files, documents (e.g., PDFs), or any other type of binary data. It is typically used when you need to store and retrieve unstructured data that cannot be easily represented in traditional relational database fields.

Blobs are designed to handle data that is too large to be stored in standard database fields, such as strings or integers. They are useful for situations where you want to associate binary data with a record in a database. For example, in a file-sharing application, you might store the actual files (images, documents, etc.) in a Blob field associated with each user's record.

The size of Blobs can vary depending on the database management system being used. Some databases may support Blobs with sizes in the megabytes or gigabytes range. There are also variations of Blob data types, such as "Text Blob" or "Image Blob," that provide specialized features or optimizations for certain data types.

When you need to work with binary data in a database, such as storing multimedia content or other large files, using Blobs is a common and efficient approach. However, it's essential to consider the storage requirements, retrieval performance, and overall design implications when using Blob data types in your database schema.
