Conceptual database design is the highest level of abstraction in the database design process. At this stage, designers focus on understanding the problem domain and defining the overall structure of the database without getting into technical implementation details. The primary goal is to cr...
As a follow-up from yesterday'spost about not lying, I wanted to discuss a bit some thoughts on abstraction levels. At first, it would appear that high-level methods lie a lot. When you ask a SqlConnection object to Open, it actually does a bunch of work: look at the connection stri...
An empirical study on end users’ update performance for different abstraction levels - Chan, K () Citation Context ...sible and, as the interfacessinevitably differ anyway, comparative analysis of extensions using their ownsimplementation is not possible as the difference in the interface would ...
It is nearly impossible to consider all the different ways that program execution in different threads could overlap with each other, and how different types of overlap can lead to different final states. Instead, database systems provide a beautiful abstraction to the application developer—a “...
adding an abstraction can help invert dependency directions so that we establish the correct dependency flows between boundaries of different software concerns. In part 2 of this post, we will delve into breaking down testing into categories and determining which strategies should be applied to each....
The manual creation of new Internet- and IT-based applications is currently a limiting factor in enabling new and innovative services to be quickly available. We advocate that semi-automated service creation techniques are feasible, whereas fully automat
In 2011, Google invented LevelDB as their answer to the IndexedDB spec designed by Nikunj Mehta. Like IndexedDB, it's quite a low-level abstraction that provides only the bare bones of what you'd need to qualify as a database – key-value storage, iteration, batch operations, and littl...

Services are a logical abstraction for managing workloads. Services can be used to divide work executing in a database cluster into mutually disjoint classes. Each service can represent a logical business function, e.g., a workload, with common attributes, service level thresholds, and priorities...
