Methods, program products, and systems for rendering data using multi-tiered caches are described. A system can render a first section of data and store the rendered first section of data in a first tier cache. The system can determine that a data field, when rendered, straddles the rendering of the first section of data and a rendering of a second section of data. The system can generate a rendering of the data field and store the rendering of the data field in a second tier cache. When rendering the second section of data, the system can use the rendered data field stored in the second tier cache instead of regenerating the rendering of the data field.

Multi-tiered caches in data rendering

Methods, program products, and systems for displaying data in formatted views using reference files are described. In some implementations, a database application program can generate a result set using one or more queries. The result set can contain actual data from a database and metadata. The metadata can contain references to data records in the database, the references can include identifiers that can identify the data records. When a user saves a database report file, the user can save at least a part of the result set using the identifiers instead of the queries and layouts. Thus, the result set can be saved as a reference file. When the database application program opens the saved reference file, the database application program can reproduce the result set using the stored references without running all of the queries.
