Béla Halassy

At the Marx Károly University of Economics (MKKE), he was taught the basics of informatics by Imre Kiss and Győző Kovács. In the summer of 1970, he was admitted to the Organizational Education Department of the Computer Training Center (Számok), which later became a department. He became the head of this (1973), and then of the department of the same name (1976). – Later, in 1982, he resigned from his managerial position at the successor institution, the Computer Application Company (Számalk), and headed a research group.

In 1972, he held the first database course in Hungary, which was followed by many others, including several international ones. He gave many lectures in English, a few in German, both at home and abroad. His lectures attracted many people. In his courses at IBM, he was introduced as "the father of databases, whose profession is halassybéla".

His first database article was published in the journal Finance and Accounting in 1972 - after the sixth rewrite. He is the author of several professional books. His works on databases were standard works for many years.

In 1972, he created his first two database designs (ARTISJUS and FSZDV), which were followed by about 30-35 additional data models and database designs in almost all areas of practical life - from companies, through museums and hospitals to the armed forces.

In 1975, he received a six-month fellowship to the data administration department of Chase Manhattan Bank in the USA. Later, he was an active member of the ANSI-SPARC (American National Standards Institute, Standards Planning And Requirements Committee) data modeling committee.

He designed several software, e.g. the SZIAM (Synthetic Data Modeler) data modeling tool, the SYDES (Systems Designer System) system design tool, the MIDAS generalized museum data management system. From 1990, he created his own programs. He was also responsible for data modeling methods in all of his later jobs.

In 2001, he started his own business, which he liquidated upon his voluntary retirement in 2006. In 2001, he created a prototype of a new approach to a generalized healthcare database system for an American company.

In 1982, the National Institute of Statistics and Statistics awarded him the Kalmár Prize for his achievements in the field of database theory and the development of a specific database management language.
