Database Machine FREND

Database Machines and Knowledge Base Machines

“…However, the performance must be evaluated in not only database management itself but also in total processing. In order to show the communication overhead, processing time is analyzed using database machine FREND [HIKI85]. A host computer and FREND are connected to LAN through LAN-adapter.…”

“…In implementing these functions of customizations, database machine must preserve the characteristic of database machines [HIKI85] [STON81] [STON83] .…”

“…Commercial database machines have been supplied since the beginning of 1980s [SHEM84][ELEC84] [EPST80] [HIKI85] and it can be said that they are at the stage of practical usage. However, field experiences of database machines show various performance problems.…”

“…database machines[HIKI85] [EPST80] only support the primitives that correspond to instructions in group (1). While, database machine V-FREND supports all instructions listed above.…”
