The application form (See Fig 4) contains all the data necessary for processing and in the event of disputes arising, marking off time and date may become an important issue. The type of data on the application form and the following legal transactions were ideal for computerisation and it was eventually decided to proceed with building a data base. Although the Department did not have a computer, the Central Government Computing Centre had sufficient space on a Vax 780 and terminals were installed in the Department and connected by land line to the central computer about one kilometre away. The Department decided to proceed with building a data base and staff were trained and much enthusiasm prevailed. Due to inexperience with data base management systems, no structuring of the data was attempted and it was decided to simply take up all the data and work out any reporting functions at a later date. The data take up began in 1983 for a system known as MTIS (Mining Tenement Information System) with all data based on the tenement number. Temporary staff were engaged and the data were taken direct from the source documents, the hand written registers where the information was recorded most of the time, and certainly in the last 20 years, under pressure of continuous high level mining activity and the original entries were never checked. By mid - 1984, there were obvious signs of trouble. The error rate of data entry was very high and added to the errors in the original data, the whole validation process became unworkable. It proved conclusively the need for data to be checked and validated before entry. All data entry ceased and a working group investigated the problems and finally concluded that the original plan to take up so much data was too ambitious and recommended that a severely reduced system should proceed. At the same time, a project manager, missing from the first exercise was appointed to co-ordinate all the activities and to design and establish a new system. During 1984, an IBM 4341 computer was installed in the Department and some data had been transferred to it from the VAX 780. 91
