Methods to persist CSV data using PowerShell on Linux?

问题

From Linux, might there be a "native" or built-in convenient "database" facility from withing Powershell itself?

While this works fine for importing data:

nicholas@mordor:~/csv$ 
nicholas@mordor:~/csv$ ll BCCDC_COVID19_Dashboard_Lab_Information.csv 
-rw-rw-r-- 1 nicholas nicholas 89153 Nov 22 05:16 BCCDC_COVID19_Dashboard_Lab_Information.csv
nicholas@mordor:~/csv$ 
nicholas@mordor:~/csv$ pwsh
PowerShell 7.1.0

Type 'help' to get help.

PS /home/nicholas/csv> 
PS /home/nicholas/csv> $labs=import-Csv labs.csv
PS /home/nicholas/csv> 

this was just so surprisingly simple and gives such at least human readable results:

..
Date        : 2020-11-19
Region      : Vancouver Coastal
New_Tests   : 2923
Total_Tests : 337615
Positivity  : 5.12
Turn_Around : 28.5

Date        : 2020-11-19
Region      : Vancouver Island
New_Tests   : 1682
Total_Tests : 118623
Positivity  : 1.4
Turn_Around : 12.7


PS /home/nicholas/csv> 

perhaps there's a utility even "lighter" than SQLite.

Using Linux, aside from persisting to a mainstream RDBMS such as:

• MySQL
• Postgres
• SQLite

how else might data such as this be persisted?

I'm more interested in retrieving such data.
