Summary
Ubiquitous information access in eHealth is hindered by diverse systems. This study proposes a service-oriented architecture using relaxed ACID properties to achieve data consistency and sustainable interoperability across heterogeneous databases.
Area of Science:
- Health Informatics
- Database Systems
- Distributed Computing
Background:
- Ubiquitous information access in eHealth is challenged by heterogeneous systems.
- Traditional databases often lack the flexibility for diverse eHealth environments.
- Ensuring data consistency across disparate systems is crucial for sustainable eHealth.
Purpose of the Study:
- To design a distributed eHealth database architecture for heterogeneous systems.
- To demonstrate how to achieve sustainability in distributed eHealth databases.
- To address the challenge of interoperability in eHealth information systems.
Main Methods:
- Review of traditional central and homogeneous distributed database architectures.
- Proposal of an architectural framework for heterogeneous eHealth databases.
- Application of relaxed ACID properties within a service-oriented architecture.
Main Results:
- A viable architectural framework for distributed eHealth databases is presented.
- Relaxed ACID properties enable data consistency in heterogeneous environments.
- Service-oriented architecture facilitates sustainable interoperability.
Conclusions:
- A service-oriented architecture with relaxed ACID properties can ensure data consistency.
- This approach overcomes limitations of traditional databases in eHealth.
- Sustainable interoperability is achievable in distributed eHealth systems.

01:20Integrated Healthcare System
An integrated healthcare system (IHS) is a set of organizations that provides for or arranges to provide coordinated and continuous service to a defined population. The IHS takes responsibility for that particular population's health status and outcome, both clinically and fiscally. An integrated healthcare system is a well-organized, well-coordinated, and collaborative network. The integrated delivery system is a network that connects different healthcare providers to deliver organized,...
01:26Design Example: Sustainability in Concrete Building
As the construction industry moves towards more eco-friendly practices, concrete's adaptability and its ability to incorporate sustainable features make it a key material in the drive towards greener building solutions.
There are multiple approaches to achieve sustainability in a commercial concrete building. For instance, construct a concrete parking area under the building, utilizing pervious concrete paver blocks in open areas to facilitate rainwater collection through an underground cistern.

01:25Distribution Reliability and Automation
Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...
01:21Distributed Loads: Problem Solving
Beams are structural elements commonly employed in engineering applications requiring different load-carrying capacities. The first step in analyzing a beam under a distributed load is to simplify the problem by dividing the load into smaller regions, which allows one to consider each region separately and calculate the magnitude of the equivalent resultant load acting on each portion of the beam. The magnitude of the equivalent resultant load for each region can be determined by calculating...
01:18Composite Masonry Walls
Composite masonry walls combine multiple wythes of the same or different masonry materials to create a unified structure. These walls feature wythes that are bonded together either through mortar-filled collar joints, grouted spaces, or more commonly, with rigid metal ties and reinforcements, with the use of masonry header units being rare. Metal ties are preferred because they effectively minimize water penetration, as these walls primarily absorb moisture and then release it into the...
01:29Issues And Trends In Healthcare Delivery System
The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
