Ana Costagliola learned more than a year ago that her employer planned to move its Boston operations — including her job as a computer database assistant — to New York.

Determined to stay in the Boston area, the 47-year-old mother of two entered Boston University’s graduate certificate program in database management to hone and expand her skills — and it paid off. A few weeks ago, she landed a better, higher-paying job as database analyst with the Boston Symphony Orchestra.

“It really opened doors,” Costagliola said of program at BU’s Metropolitan College. “It gave me a little extra edge to advance my career.”

Costagliola is among the many people taking advanced, post-college courses to build skills sought by Massachusetts’ fastest growing industries and open doors to new jobs and careers. As Costagliola’s experience shows, many of the high-demand fields are in technology, but health care, biopharamaceuticals, and other industries also have demand for workers with special skills.
