Data Science Model Deployments and Cloud Computing on GCP - In-Memory Databases

The video tutorial introduces in-memory databases, which store data in RAM instead of on disk, making data access faster but less permanent. It highlights that data does not persist through sessions and explains that in-memory databases often use key-value pairs rather than collections. An example is provided, and the video concludes with a mention of Redis, an in-memory database to be discussed in a future video.

What is a key advantage of using in-memory databases over traditional disk-based databases?

• They provide more storage capacity.

• They are more secure.

• They offer faster data access.

• They are cheaper to maintain.

What is a key characteristic of in-memory databases in terms of data storage?

• They use relational tables.

• They rely on document-based storage.

• They use key-value pairs.

• They store data in collections.

How do in-memory databases typically handle multiple entries?

• By using document-based collections.

• By using relational tables.

• By spreading them across multiple databases.

• By storing them in a single database.

What is an example of a key-value pair in an in-memory database?

• Age: 30

• Address: 123 Main St

• Phone number: 555-1234

• First name: Scott

Which in-memory database will be discussed in the next video?

• MongoDB

• Cassandra

• MySQL

• Redis
