3 functionalities of a database?

- specialized language to query (retrieve data) - specialized modeling strategies to optimize retrieval for different use cases - more fine-tune control over the transformation of the data into useful data structures or reports

Data warehouses are generally designed to be HOT. What does HOT mean?

Hot means they can return queries very fast even though they have vast amounts of data

What would you call a relational datastore designed for analytic workloads, which is generally column-oriented data-store

a Data warehouse

How often is data from a data warehouse accessed?

infrequently accessed meaning they aren’t intended for real-time reporting but maybe once or twice a day or once a week to generate business and user reports.

Cloud storage

Persistent Disk How is data stored? How is data accessed? Does it have a write volume?

- Data is split into evenly split blocks - Directly accessed by the Operation System - Supports only a single write volume

Filestore - What is stored with a file? - Can multiple people access it? - Can different people simultaneously read and write the file?

Low latency - time to first byte typically tens of milliseconds)

What are the available storage classes? What are each minimum storage duration?

- Standard Storage (0 day min) – when you are frequently using files. The least cost-effective - Nearline Storage (30 day min) – when you will only access a file once per month, cheaper than standard. - Coldline Storage (90 day min) – higher access cost than nearline store but lower at-rest cost Archive Storage (365 day min) – very slow retrieval, very cost-effective, rarely or never intended to be accessed

What storage class would you use when you are frequently using files or general use. How cost-effective is this?
