Description
Technical Field
The invention relates to an asset management system, in particular to a system for realizing data sharing service based on a multi-view data directory, and further relates to a method for realizing data sharing based on the multi-view data directory.
Background
Data assets refer to data resources that are physically or electronically recorded, owned or controlled by an individual or business, and that can bring future economic benefits to the business. Leaving high quality data, it is difficult for an enterprise to still operate efficiently. Today, enterprises rely on their data assets to make more informed and effective decisions. Market leaders are taking advantage of data assets to gain competitive advantages through rich client data, innovative use of information, and efficient operations. Enterprises provide better products and services, reduce cost and control risks through data assets. With the increasing demand and the increasing dependence of enterprises on data, people can clearly evaluate the business value of data assets.
In recent years, a power grid company develops the pilot construction of a data resource management platform, preliminarily realizes the centralized control of aspects such as main data management, metadata management, data quality management, data standard management and the like, has the management capability on data assets, improves the cross-system business cooperation level and the data quality management level, and lays a foundation for 'data management enterprises'.
Moreover, with the further development of the related working technologies, some power grid companies propose new industrial development layouts, and the data supply side is required to be reformed and upgraded from the aspect of visitation, so that the three-full coverage of the whole company, the whole field and the whole service of the data assets and the two-full upgrade of the real-time and fusion of the data processing are realized, the open sharing of the data is further realized, the development needs of the service are supported by means of more real-time and efficient, and the multi-channel change of the data value is realized.
Facing new challenges, but most companies currently have some shortcuts in data asset management: for example, the data management work lacks overall planning, and the system mechanism is to be perfected; the data standard is missing or is not executed in place, all systems are difficult to collaborate and fuse for application, and the data island phenomenon still exists; the data supply capacity is insufficient, the data acquisition difficulty is high, the threshold is high, and the requirement of service development cannot be quickly met; the data value conversion capability is insufficient, and diversified data value realization ways are lacked; the overall awareness of data security is insufficient, and the data security guarantee capability is weak. These problems severely restrict and impact the healthy and orderly development of corporate data asset management.
The metadata is data describing data, mainly information describing data attributes, and generally may include technical metadata, business metadata, management metadata, and the like, and although some enterprises have implemented metadata management, data dictionaries, and business glossaries, only technical metadata that can be collected automatically is basically collected, and business metadata and management metadata are basically collected manually at present. As data growth rates far exceed the number of data managers, enterprise users are faced with more and larger data sources, in addition to all data about customers, products, sales, employees, and suppliers, such as from social media, the internet of things, and other types of behavioral data, such as website click streams. This in fact represents a bottleneck in the availability of metadata management personnel in the current data asset management approach. Further, because of the imprecision of definitions, incomplete information, and stale metadata or inability to find the desired information, more metadata is required to understand the data assets stored in the data warehouse. In addition, these systems and applications are generally developed by IT personnel at present, and due to the difference between the thinking and technical language of IT personnel and business personnel, the business users are more complicated and difficult to acquire data.
Although the metadata cannot completely solve all the problems faced by the current data asset management, the metadata can be used as a basis for constructing a data asset directory, which is equivalent to the background of the data asset directory and is responsible for collecting metadata of a plurality of business systems. However, most of the current power grid enterprises have not realized the application of managing enterprise data assets by constructing a data asset directory.
