IndexedDB is an object database that is simpler than databases that support SQL queries. However, it is more powerful, efficient, and robust than the key/value storage offered by the Web Storage API.

In the IndexedDB API, a database is just a collection of object stores that have been given names.
A database in the IndexedDB API is simply a collection of object stores with names.
In the IndexedDB API, a database consists of named object stores.
The IndexedDB API defines a database as a collection of named object stores.

A key path is a value that specifies how the database should extract an object's key from the object itself.
A key path is a value that tells the database how to obtain an object's key from the object itself.
A key path is a value that defines how the database should retrieve an object's key from the object.
A key path is a value that indicates to the database how to extract an object's key from the object.

With IndexedDB, queries and updates to the database are grouped within a transaction to ensure that they either all succeed or all fail together, thereby preventing the database from being left in an undefined, partially updated state.
IndexedDB ensures the atomicity of queries and updates to the database by grouping them within a transaction. This means that all updates must either succeed or fail together, and the database will never be left in an undefined, partially updated state..
IndexedDB provides atomicity guarantees by grouping queries and updates to the database within a transaction. This ensures that all updates either succeed or fail together, preventing the database from being left in an undefined, partially updated state..
In IndexedDB, queries and updates to the database are grouped within a transaction to ensure atomicity. This means that all updates must either succeed or fail together, and the database will never be left in an undefined, partially updated state.

One of the useful aspects of the IndexedDB API is that it makes it easy to manage transactions.

Another advantage of the IndexedDB API is that it allows you to create indexes on object stores, which enables you to search for objects based on the values of their properties other than the primary key.
This can be useful if you need to retrieve objects from an object store using criteria other than the primary key value.
For example, you might want to search for all objects with a certain property value, or all objects within a certain range of values for a given property. By defining indexes on an object store, you can perform these types of searches efficiently.

The get() method of an object store can be used to retrieve an object.
The put() method of an object store can be used to store a new object.
Both the get() and put() methods allow you to access and modify the data stored in an object store.

To search for objects within a range of key values, you can use the openCursor() method of an object store along with an IDBRange object.
This allows you to retrieve all objects within a specified range of key values.

A Blob is an oblique reference or handle to a piece of data. The name is derived from SQL databases and means "Binary Large Object."

A Blob object represents an immutable, raw data file-like object. Blobs are used to represent data that isn't always in a JavaScript-native format.
Blobs are opaque; the only things you can do with them are determine their size in bytes, request their MIME type, and chop them up into smaller Blobs.

A Blob object represents an immutable, raw data file-like object. Blobs can be stored in memory or on disc by the web browser, and they can represent truly massive chunks of data (such as video files) that are too large to fit in main memory without first being divided into smaller pieces with slice ().

The File interface is based on the Blob interface, inheriting blob functionality and expanding it to support files on the user's system. Blobs can be stored in memory or on disc by the web browser, and they can represent truly massive chunks of data (such as video files) that are too large to fit in main memory without first being divided into smaller pieces with slice ().

Blobs are used to represent data that isn't always in a JavaScript-native format.
The structured clone algorithm supports blobs, which means you can obtain one from another window or thread using the message event.
