Apache Metamodel

Apache Metamodel provides a common interface for discovery, exploration of metadata and querying of different types of data sources. Uniform connector and query API for CSV & data formats, relational databases, noSQL databases.

With MetaModel you use a type-safe SQL-like API for querying any datastore:

DataContext dataContext = DataContextFactory.create[TypeOfDatastore](...);
DataSet dataSet = dataContext.query()
    .from("libraries")
    .select("name")
    .where("language").eq("Java")
    .and("enhances_data_access").eq(true)
    .execute();

The MetaModel query API allows you to use the power of SQL, even on data formats such as CSV files, Excel spreadsheets, NoSQL databases and more.
