Query: TOPCAT's TAP Client   TAP, the Table Access Protocol, is a Virtual Observatory (VO) protocol for
executing queries in remote relational databases using ADQL, an SQL-like query
language. It is one of the most powerful components of the VO, but also one of
the most complex to use, with an extensive stack of associated standards.
  We present here recent improvements to the client and GUI for interacting
with TAP services from the TOPCAT table analysis tool. As well as managing
query submission and result retrieval, the GUI attempts to provide the user
with as much help as possible in locating services, understanding service
metadata and capabilities, and constructing correct and useful ADQL queries.
The implementation and design are, unlike previous versions, both usable and
performant even for the largest TAP services.
