I also agree that virtual table is good approach to us.
The first trial is to make this work closer to 'information schema', even
through the details are different to the standard specification of 'information
schema'.
In this sense, I'd like to suggest as follows:
* All names of databases and tables should be lower cases.
* database name 'SYSTEM' to 'information_schema'
* SYSTEM.DATABASE_ should be 'information_schema.databases'
I'll also leave more comments soon.

> Project: Tajo
> Issue Type: Improvement
> Reporter: Jihun Kang

> Priority: Trivial
> Fix For: 0.9.1

>
> I would like to propose queryable interfaces for catalog information. And
> these information may contain tables, columns, any other information on tajo
> catalog.
> Currently, TajoCli offers some meta commands for retrieving table list,
> however queryable virtual tables can provide a handy way to tajo users.
