A database management system for performing a graph query based on one or more graph views of a relational-graph database is disclosed. The database management system is configured to determine a plurality of graph views from the relational-graph database based on one or more previous graph queries of the relational-graph database to obtain a plurality of candidate graph views of the relational-graph database. Moreover, the database management system is configured to store a subset of the plurality of candidate graph views of the relational-graph database and perform a graph query of the relational-graph database based on the subset of the plurality of candidate graph views of the relational-graph database. By virtue of the selected subset of the plurality of candidate graph views from the relational-graph database, the database management system can increase the processing speed of graph queries.

Aspects of this disclosure relate to selective removal of material of a layer, such as a carbon-containing layer. The layer can be over a patterned structure of two different materials. Treating the layer to cause the removal agent to be catalytically activated by a first area of the patterned structure to remove material of the organic material over the first area at a greater rate than over a second area of the patterned structure having a different composition from the first area.
