EspressReport ES provides several ad hoc reporting and query features that allow users to create a wide range of queries and reports through a zero-client browser interface. Unlike some other tools, ERES provides a simple query interface that is geared towards business users, not high-level analysts. With these tools users can create queries, build reports and charts from any data source, and publish the results without any training.
The data view interface shields users from database complexity, by allowing administrators to pre-define tables, joins, fields, and even filters creating in effect a local schema. End-users can then select (typically aliased) fields, and perform ordering, sorting, filtering, and aggregation without any knowledge of the underlying database structures.
