Besides singing Madonna has the ability to play several musical instruments. She learned to play drum and guitar from her then-boyfriend Dan Gilroy in the late 1970s before joining the Breakfast Club line-up as the drummer. This helped her to form the band Emmy, where she performed as the guitarist and lead vocalist. Madonna later played guitar on her demo recordings. On the liner notes of Pre-Madonna, Stephen Bray wrote: "I've always thought she passed up a brilliant career as a rhythm guitarist." After her career breakthrough, Madonna focused mainly in singing but was also credited for playing cowbell on Madonna (1983) and synthesizer on Like a Prayer (1989). In 1999, Madonna had studied for three months to play the violin for the role as a violin teacher in the film Music of the Heart, before eventually leaving the project. After two decades, Madonna decided to perform with guitar again during the promotion of Music (2000). She took further lessons from guitarist Monte Pittman to improve her guitar skill. Since then Madonna has played guitar on every tour, as well as her studio albums. At the 2002 Orville H. Gibson Guitar Awards, she received nomination for Les Paul Horizon Award, which honors the most promising up-and-coming guitarist.

On May 20, 1971, his brother, Meinhard, died in a car accident. Meinhard had been drinking and was killed instantly. Schwarzenegger did not attend his funeral. Meinhard was due to marry Erika Knapp, and the couple had a three-year-old son, Patrick. Schwarzenegger would pay for Patrick's education and help him to emigrate to the United States. Gustav died the following year from a stroke. In Pumping Iron, Schwarzenegger claimed that he did not attend his father's funeral because he was training for a bodybuilding contest. Later, he and the film's producer said this story was taken from another bodybuilder for the purpose of showing the extremes that some would go to for their sport and to make Schwarzenegger's image more cold and machine-like in order to fan controversy for the film. Barbara Baker, his first serious girlfriend, has said he informed her of his father's death without emotion and that he never spoke of his brother. Over time, he has given at least three versions of why he was absent from his father's funeral.
What is Meinhard's son named?
Patrick

Sometimes it is desired to bring a database back to a previous state (for many reasons, e.g., cases when the database is found corrupted due to a software error, or if it has been updated with erroneous data). To achieve this a backup operation is done occasionally or continuously, where each desired database state (i.e., the values of its data and their embedding in database's data structures) is kept within dedicated backup files (many techniques exist to do this effectively). When this state is needed, i.e., when it is decided by a database administrator to bring the database back to this state (e.g., by specifying this state by a desired point in time when the database was in this state), these files are utilized to restore that state.
Name a reason to take a database backward in time?
