Building Efficient Query Engines in a High-Level Language

Christoph Koch, Ioannis Klonatos, Tiark Rompf, Hassan Chafi

In this paper we advocate that it is time for a radical rethinking of database systems design. Developers should be able to leverage high-level programming languages without having to pay a price in efficiency. To realize our vision of abstraction without ...

ScalaDyno: Making Name Resolution and Type Checking Fault-tolerant

Martin Odersky, Vlad Ureche, Cédric Bastin

The ScalaDyno compiler plugin allows fast prototyping with the Scala programming language, in a way that combines the benefits of both statically and dynamically typed languages. Static name resolution and type checking prevent partially-correct code from ...

Incremental Query Evaluation in a Ring of Databases

Christoph Koch

This article approaches the incremental view maintenance problem from an algebraic perspective. The algebraic structure of a ring of databases is constructed and extended to form a powerful aggregate query calculus. The query calculus inherits the key prop ...

Embedded Domain-Specific Languages using Libraries and Dynamic Metaprogramming

Gilles Dubochet

Domain-specific programming is bound to play a central role in improving the productivity of writing software. This is because modern, intricate, general-purpose abstractions are rarely applicable directly to everyday programming. However, such abstraction ...

JReq: Database Queries in Imperative Languages

Willy Zwaenepoel, Emmanuel Cecchet, Christopher Ming-Yee Iu

Instead of writing SQL queries directly, programmers often prefer writing all their code in a general purpose programming language like Java and having their programs be automatically rewritten to use database queries. Traditional tools such as object-rela ...
