The acronym CRUD represents an interface speciication and an algorithm for the management of memory shared by concurrent processes. The memory cells form a directed acyclic graph. This graph is only modiied by adding a new node with a list of reachable children, and by removing unreachable nodes. If memory is not full, the algorithm ensures waitfree redistribution of free nodes. It uses atomic ...

This work introduces the CRUDI Framework for management and decision support in Information Systems investments, based in the proposed CRUDI Matrix. The CRUDI Matrix is an abstraction idealized from the CRUD Matrix which was extended by an extra dimension: the Importance dimension. The CRUDI example application presented in this paper generates relevant information regarding issues such as the ...

This paper reports the results obtained with a group of 24 14-year-old students when presented with a set of algebra tasks by the Leeds Modelling System, LMS. These same students were given a comporoble paper-and-pencil test crud detailed interviews some four months later. The latter studies uncovered several kinds of student misunderstandings that LMS had not detected. Some students had profou...

The art of Information Engineering (IE) continuously evolves and, by today's standards, is considered an integral function in most any organization. Strategic planning teams weave methodologies, which are integrated to process information, the goal being to sort, store, and retrieve useful data. The following article will describe three techniques that can utilize existing information engineeri...

This case comprises several primitive tasks that can be solved straight away with most transformation tools. The aim is to cover the most important kinds of primitive operations on models, i.e. create, read, update and delete (CRUD). To this end, tasks such as a constant transformation, a model-to-text transformation, a very basic migration transformation or diverse simple queries or in-place o...
