STORE: EMBEDDED PERSISTENT STORAGE FOR CLOJURE PROGRAMMING LANGUAGE Konrad Grzanek1 1IT Institute, Academy of Management, Lodz, Poland [email protected] Abstract Functional programming is the most popular declarative style of programming. Its lack of state leads to an increase of programmers' productivity and software robustness. Clojure is a very effective Lisp dialect, but it misses a solid embedded database implementation. A store is a proposed embedded database engine for Clojure that helps to deal with the problem of the inevitable state by mostly functional, minimalistic interface, abandoning SQL and tight integration with Clojure as a sole query and data-processing language. Key words: Functional programming, Lisp, Clojure, embedded database 1 Introduction Functional programming languages and functional programming style in general have been gaining a growing attention in the recent years. Lisp created by John McCarthy and specified in [8] is the oldest functional pro- gramming language. Some of its flavors (dialects, as some say [9]) are still in use today. Common Lisp was the first ANSI standardized Lisp dialect [13] and Common Lisp Object System (CLOS) was probably the first ANSI stan- dardized object oriented programming language [14]. Apart from its outstand- ing features as a Common Lisp subset. Various Lisps were used in artificial intelligence [11] and to some extent the language comes from AI labs and its ecosystem. Common Lisp was used as the language of choice by some AI tutors, like Peter Norvig (in [10]). But the whole family of languages address general problems in computer science, not only these in AI. John Backus argues [3] that the functional style is a real liberation from the traditional imperative languages and their problems. -

A Variability-Aware Module System
A Variability-Aware Module System Christian Kästner, Klaus Ostermann, and Sebastian Erdweg Philipps University Marburg, Germany Module systems enable a divide and conquer strategy to software develop- ment. To implement compile-time variability in software product lines, mod- ules can be composed in different combinations. However, this way variability dictates a dominant decomposition. Instead, we introduce a variability-aware module system that supports compile-time variability inside a module and its interface. This way, each module can be considered a product line that can be type checked in isolation. Variability can crosscut multiple modules. The module system breaks with the antimodular tradition of a global variabil- ity model in product-line development and provides a path toward software ecosystems and product lines of product lines developed in an open fashion. We discuss the design and implementation of such a module system on a core calculus and provide an implementation for C, which we use to type check the open source product line Busybox with 811 compile-time options. 1 Introduction A module system allows developers to decompose a large system into manageable sub- systems, which can be developed and checked in isolation [13]. A module hides informa- tion about internal implementations and exports only a well-defined and often machine- enforced interface. This enables an open-world development style, in which software can be composed from modular self-contained parts. The need for compile-time variability, for example in software product lines [6, 17, 10], challenges existing module systems. To tailor a software system, stakeholders may want to select from compile-time configuration options (or features) and derive a specific configuration (or variant, or product) of the system. -

Portability Techniques for Embedded Systems Data Management
Portability Techniques for Embedded Systems Data Management McObject LLC st 33309 1 Way South Suite A-208 Federal Way, WA 98003 Phone: 425-888-8505 E-mail: [email protected] www.mcobject.com Copyright 2020, McObject LLC Whether an embedded systems database is developed for a specific application or as a commercial product, portability matters. Most embedded data management code is still “homegrown,” and when external forces drive an operating system or hardware change, data management code portability saves significant development time. This is especially important since increasingly, hardware’s lifespan is shorter than firmware’s. For database vendors, compatibility with the dozens of hardware designs, operating systems and compilers used in embedded systems provides a major marketing advantage. For real-time embedded systems, database code portability means more than the ability to compile and execute on different platforms: portability strategies also tie into performance. Software developed for a specific OS, hardware platform and compiler often performs poorly when moved to a new environment, and optimizations to remedy this are very time-consuming. Truly portable embedded systems data management code carries its optimization with it, requiring the absolute minimum adaptation to deliver the best performance in new environments. Using Standard C Writing portable code traditionally begins with a commitment to use only ANSI C. But this is easier said than done. Even code written with the purest ANSI C intentions frequently makes assumptions about the target hardware and operating environment. In addition, programmers often tend to use available compiler extensions. Many of the extensions – prototypes, stronger type- checking, etc, – enhance portability, but others may add to platform dependencies. -
RDM Embedded Database Dataflow Paper
BUSINESS WHITE PAPER RDMe dataFlow with Raima Databases A Raima Inc. Business White Paper Published: February, 2010 Author: Paul Johnson Director of Marketing Copyright: Raima Inc. Abstract Today, the need for real-time data throughout the many levels of an organization is growing rapidly. The more current a company’s business intelligence information often determines how successful a business is run. Traditionally, embedded applications have been closed systems. The movement of any data collected on these devices to the company’s enterprise business systems is performed via off line batch processing at periodic intervals. This paper outlines three separate business cases applicable within three key industry market segments: Industrial Automation; Telecommunication; and Aerospace and Defense; where Raima technologies facilitate high speed data management and seamless real-time data flow between embedded devices and corporate enterprise databases. Additionally, this paper will outline (currently available upon request) a demonstration that highlights the use of the RDM embedded databases and dataFlow technologies on real-time embedded computers (devices), desktop and servers platforms. The demonstration relies on Raima technology partners’ technology from Microsoft®, Wind River®, and Green Hills® Software.

BIM AND SENSOR BASED DATA MANAGEMENT SYSTEM FOR CONSTRUCTION SAFETY MONITORING ABSTRACT Purpose: This research investigates the integration of real-time monitoring of thermal conditions within confined work environments through wireless sensor network (WSN) technology when integrated with Building Information Modelling (BIM). A prototype system entitled Confined Space Monitoring System or CoSMoS (which provides an opportunity to incorporate sensor data for improved visualization through new add-ins to BIM software) was then developed. Design/ methodology/ approach: An empirical study was undertaken to compare and contrast between the performance (over a time series) of various database models to find a back-end database storage configuration that best suits the needs of CoSMoS. Findings: Fusing BIM data with information streams derived from wireless sensors challenges traditional approaches to data management. These challenges encountered in the prototype system are reported upon and include issues such as hardware/ software selection and optimisation. Consequently, various database models are explored and tested to find a database storage that best suits the specific needs of this BIM-wireless sensor technology integration. Originality/ value: This work represents the first tranche of research that seeks to deliver a fully integrated and advanced digital built environment solution for automating the management of health and safety issues on construction sites. 1 KEYWORDS Building information modelling, digital built environment, health and safety management, sensor data, data management INTRODUCTION According to U.S. Bureau of Labor Statistics (BLS), a total of 796 fatal injuries were recorded in the U.S. construction industry in 2013 from which 14% of fatalities were due to the exposure to hazardous environment and 2% were caused by fire and explosions (BLS, 2013).
