CsvJdbc is a read-only JDBC driver that uses Comma Separated Value (CSV) files or DBF files as database tables. It is ideal for writing data import programs or analyzing log files. The driver enables you to access a directory or a ZIP file containing CSV or DBF files as if it were a database containing tables. As there is no real database management system behind the scenes, not all JDBC functionality is available.
Immutables allows you to embrace immutablity to tackle complexity and concurrency challenges.

You can think of it as Guava's Immutable Collections but for regular objects. It includes support for JSON marshaling, MongoDB repositories, and JAX-RS.
