The Objective of Open Data

3 The framework of open data

3.1 The Principles of Overall Design

Openness is a necessary process for system interconnection and data interaction; that is an important prerequisite to improve the maintenance of the system. From many aspects, openness can be reflected from the design of system architecture, database systems, operating systems, network, etc. It is convenient to adopt modular framework for a third party supplying a cross platform development tool. Alsoit is a continuous process to improve API and services relying on the feedback of the public and government departments.

One important aspect of designing a framework is making sure the extensibility of the framework has been carefully considered. There isno dispute that data volumes are growing exponentially. Huge amounts of data are generated every hour of every day, and this data comes from an ever-increasing variety of sources. This requires system design to be considered from two aspects: one is high scalability of hardware; the other is component-based design of software.

Accessibility is the degree to which a product, device, service, or the environment is available to as many people as possible. Accessibility can be viewed as the "ability to access" and benefit from some system or entity. The design objectives of open data are to strengthen the accessibility, utilization and availability of data. In data publishing and permission management, it is effective to ensure that published data can meet the needs of users, and this requires it based on the maximum degree of data sharing. On the other hand, providing high-value data sets released, without involving privacy, confidentiality, safety issues, should be based on the needs of each government department and the public. In data presentation, the public can easily get what they need through open data portal.

There is no requirement that every dataset must be madeopen right now. Starting out by opening up just one dataset, or even one part of a large dataset, is fine – of course, the more datasets one can open up the better. Remember, moving as rapidly as possible is good because it means one can build momentum and learn from experience – innovation is as much about failure as success and not every dataset will be useful.

Maintainability involves a system of continuous improvement – learning from the past in order to improve the ability to maintain systems, or improve reliability of systems based on maintenance experience. In other words, the maintainability of the system expressed as the probability that a system will be retained in or restored to a specified condition within a given period or expressed as the actual operating costs of the system. The availability of the system can be reflected from two aspects: hardware and software. Hardware equipment should be convenient for installation and upgrade; it should also have sufficient spare parts. Software should provide flexible and user-friendly admin interface for operators.

Security provides "a form of protection where a separation is created between the assets and the threat." These separations are generically called "controls," and sometimes include changes to the asset or mitigrate the threat. Generally, it is useful to ensure absolute security through permissions setting, security certifications, anonymization technique and other means.

Advancement is responsible for maintaining the data in Advance Client/Server(C/S), and relations database. This responsibility involves processing all data and keeping the data in database current. The system will use object-oriented design; use the web access technology in user interface design and then fully guarantee the requirements of application systems design and development.
