Nima uchun ma'lumotlar bazalarini o'rganish kerak?

• Ma'lumotlar hamma joyda mavjud va bizning hayotimiz uchun juda muhimdir
• Ma'lumotlar to'g'ri, xavfsiz, samarali tarzda yozilishi, saqlanishi, kiritilishi va boshqarilishi kerak
• At the “low end”: scramble to web-scale (a mess!)
• At the “high end”: scientific applications
• Database management systems (DBMSs) are indispensable software for achieving such goals
• The principles and practices of DBMSs are now an integral part of computer science curricula
• They encompass OS, languages, theory, AI, multimedia, and logic, among others

• As such, the study of database systems can prove to be richly rewarding in more ways than one!
