Ta-da! All the information's here (7)
I believe the answer is:
dataset
'ta-da all' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'information's here' is the wordplay.
'information' becomes 'data' (data are bits of information).
'here' becomes 'set' (I can't justify this - if you can you should believe this answer much more).
'data'+'set'='DATASET'
'the' acts as a link.
Can you help me to learn more?
(Another definition for dataset that I've seen is " file".)
