RE: List of schemas and tables via JDBC?

There's a pretty good explanation here https://www.simple-talk.com/sql/t-sql-programming/exploring-your-database-schema-with-sql/ though it focuses on SQL Server.

E F Codd's fifth rule (rule no. 4) says that to be a relational database a system must have a catalog of its parts that can be queried using the same language used for querying ordinary tables. This "schema" was standardized in SQL-98, I think, with a standard meta-schema name "INFORMATION_SCHEMA" and tables within that schema "TABLES", "TABLE-CONSTRAINTS", "VIEWS", "TRIGGERS", and so on. See here for a good list http://dev.mysql.com/doc/refman/5.0/en/information-schema.html. Before that all the databases supported the systables, sysviews, sysconstraints, etc. de facto naming convention.

So, the JDBC standard doesn't need to provide any methods for querying for a list of schemas as SQL itself already has defined them.

Subject: List of schemas and tables via JDBC?

I haven't even started looking, but would anybody happen to know where I
need to look, for how one gets a list of databases/schemas/tables
available at any given JDBC URL?

And are the relevant methods already exposed in JDBCR4?

(I'm beginning to think that by the time I'm done with extensions to
JDBCR4, it will be more like JDBCR4000.)
