Dynamic hashing schemes
1988
ACM Computing Surveys
Preserved Fulltext
A new type of dynamic file access called dynamic hushing has recently emerged. It promises the flexibility of handling dynamic tiles while preserving the fast access times expected from hashing. ...
Such a fast, dynamic file access scheme is needed to support modern database systems. This paper surveys dynamic hashing schemes and examines their critical design issues. ...

Domain specific modeling (DSM) has become popular in the software development field during these last years. ...
In doing so, it proposes three rules to compose DSMLs by composing there metamodels: reference rule, specialization rule and fusion rule. ...
In addition, this extending mechanism limits a DSL to only extend one other. Regarding the dynamic semantics of the DSL, it can be implemented using other languages such as Xtend [64] . ...
