Abstract
This thesis presents new techniques for data management of run-time data objects
in component-based embedded real-time systems. These techniques enable
data to be modeled, analyzed and structured to improve data management
during development, maintenance and execution.
The evolution of real-time embedded systems has resulted in an increased
system complexity beyond what was thought possible just a few years ago.
Over the years, new techniques and tools have been developed to manage software
and communication complexity. However, as this thesis show, current
techniques and tools for data management are not sufficient. Today, development
of real-time embedded systems focuses on the function aspects of the
system, in most cases disregarding data management.
The lack of proper design-time data management often results in ineffective
documentation routines and poor overall system knowledge. Contemporary
techniques to manage run-time data do not satisfy demands on flexibility,
maintainability and extensibility. Based on an industrial case-study that identifies
a number of problems within current data management techniques, both
during design-time and run-time, it is clear that data management needs to be
incorporated as an integral part of the development of the entire system architecture.
As a remedy to the identified problems, we propose a design-time data entity
approach, where the importance of data in the system is elevated to be
included in the entire design phase with proper documentation, properties, dependencies
and analysis methods to increase the overall system knowledge.
Furthermore, to efficiently manage data during run-time, we introduce database
proxies to enable the fusion between two existing techniques; Component
Based Software Engineering (CBSE) and Real-Time Database Management
Systems (RTDBMS). A database proxy allows components to be decoupled
from the underlying data management strategy without violating the component
encapsulation and communication interface.
