Determine the minimal set of functional dependencies for the following data.
This table is part of the OHSU database of extracurricular activities and tracks the DMICE band's concerts for charities. The DMICE band performs many concerts each year (they're in high demand!). For each concert, a faculty, staff, or student member of the department volunteers to direct the organization of the concert, and a different member of the department volunteers to be the featured performer (thus lessening the burden of practicing time and effort on the other members of the band). Concerts are held both in Portland and its suburbs, and concerts may be given names.There is never more than one concert a day." Sometimes the concert names are used more than once, but always for concerts held in the same city/suburb (i.e. the "Beaverton Bash" held in Beaverton in 2012 and the "Beaverton Bash" held in Beaverton in 2013). Each concert benefits a charity, and the concert director coordinates with a contact person from that charity. Charities may be benefitted more than once, and the contact person for a charity may vary with each benefit, but there will be only one for each performance.
