| Abstract: |
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. |
