Question: Who developed the first language compiler and when?
Answer: Rear Admiral Dr. Grace Murray Hopper, in 1949. The compiler, written in assembly language, converted symbolic mathematical code into machine code.
By 1949 programs contained mnemonics that were transformed into binary code instructions executable by the computer. Admiral Hopper and her team extended this improvement on binary code with the development of her first compiler, the A-O. The A-O series of compilers translated symbolic mathematical code into machine code, and allowed the specification of call numbers assigned to the collected programming routines stored on magnetic tape. One could then simply specify the call numbers of the desired routines and the computer would “find them on the tape, bring them over and do the additions. This was the first compiler,” she declared.

Every second of every day, consumers are initiating electronic payment transactions — getting cash at ATMs, using debit and credit cards to make purchases in stores and on the Internet, banking by phone and PC, paying bills online. Over 90 billion times a year, ACI software is used to process these transactions, powering the world's online payment systems.
With millions of transactions to process every day, ACI needed technology that could meet peak performance requirements and sustain maximum throughput. ACI considered a number of databases during the design phase of the project. Only the ISAM architecture of c-tree could consistently sustain the required performance levels. This performance, truly the hallmark of c-tree, continued to grow as the hardware horsepower of the project was put in place and optimized.
