Master file was one of the first database programs available for the Amstrad micros, and still holds up quite well against the full CP/M offerings. Masterfile 128 is a revised and improved version of the original, and although only available direct from Campbell at present, it will soon be added to the 464/664 version available from Amsoft. This database is relational, which means you can call up details of a record on one file by referring to a related record on another The uses of this facility may not at first be obvious. Take an example, though If ycou were keeping an index of books on a Masterfile database you might have ten by Russell Hoban. Each book record would have to have the full author's name against its title, and you would therefore have the letters 'Russell Hoban' on your file 10 times. Multiply this by all the other authors whose books you like, and you should see you're wasting quite a bit of space. Master file, however, allows you to set up a parent file with all the authors' names on it and to use two-character references to link them to child records on a different file, which have details of all the book titles. You can still refer to the child file if you want to deal with your books by title. The program can sort a file and seareh through it using a system of selecting and de-selecting records. You can therefore create any subset you like by flagging only the records you want to keep on file. You can't save a sub-set, though You can keep totals of fields in a Master file file, but you can't perform any other calculations on numeric data. Against this, you can freely design your record screen and put in frames and divider s at will , by selecting from a aeries of menus. This isn' t quite as easy as designing a record on screen, but the finished record can look very effective. Overall, Masterfile is an effective database, but is perhaps not the easiest to get to grips with. Amstrad Action #6 | ★ AMSTRAD CPC ★ DOWNLOAD ★ |

Page créée en 070 millisecondes et consultée 1728 foisL'Amstrad CPC est une machine 8 bits à base d'un Z80 à 4MHz. Le premier de la gamme fut le CPC 464 en 1984, équipé d'un lecteur de cassettes intégré il se plaçait en concurrent du Commodore C64 beaucoup plus compliqué à utiliser et plus cher. Ce fut un réel succès et sorti cette même années le CPC 664 équipé d'un lecteur de disquettes trois pouces intégré. Sa vie fut de courte durée puisqu'en 1985 il fut remplacé par le CPC 6128 qui était plus compact, plus soigné et surtout qui avait 128Ko de RAM au lieu de 64Ko. |
