What is data sharing ?

Data sharing is the process of putting the same data resources available to several applications, users or organizations. It includes technologies, practices, legal frameworks and cultural elements that facilitate secure access to data for multiple entities without compromising data integrity. Data sharing improves efficiency within an organization and promotes collaboration with suppliers and partners. The awareness of risks and opportunities related to data sharing is an integral part of the process.

Why is data sharing important for companies ?

Organizations have shared data since the advent of the Internet. However, the progress of digital culture, technology and the adoption of the cloud has led to sharing data on an unprecedented scale. Here are three key factors that have contributed to the growth in data sharing:

  • Storage, processing, processing and data transfer technologies are increasingly available and affordable
  • A new state of mind in the industry processes data as a resource and an asset
  • Policies and regulations have changed and aim to reduce the risks linked to data sharing

Modern companies understand that data sharing is essential to improve relationships with the community and create new commercial opportunities. We present below some of these advantages.

Better value for customers

The combination of information from different data sources has the potential to increase both the value and performance of the services. This approach promotes better research and better product development. For example, WB Games, the Warner Bros video games division. use data sharing to contribute to the creative process of developing its games. She captures, ingests, analyzes and acts on ideas to help her developers become more opportunistic and flexible in their narration.

Data oriented decision -making

By sharing the information transparently, the teams break the data silos and contribute to the improvement of the analyzes. Decisional IT is improving and the parties concerned make long -term influential decisions. For example, Ge Renewable Energy has more than 49,000 wind turbines installed and producing wind electricity worldwide. GE turbines are equipped with sensors and connected to advanced networks that collect data on temperature, wind speed, electricity and other factors related to turbine performance. The GE data analytical system facilitates decision -making for the maintenance and productivity of turbines.

Positive social impact

Public authorities and organizations can share more data in a secure, legal and respectful manner. This creates new collaboration possibilities that benefit the whole community. For example, data sharing efforts in the health sector contribute positively to medical research, which leads to events such as considerable progress in the field of genomic research.

What are the risks linked to data sharing ?

Data disclosure includes risks in terms of regulation, competition, finance and security. We emphasize some critical threats below.

Disclosure of confidentiality

Each organization has the legal and ethical obligation to protect the confidentiality of customer data that it has. They must take appropriate measures to share data without compromising privacy. Privacy preservation technologies such as encryption and censorship allow you to share data safely.

Different data interpretation

The lack of communication between producers and data consumers can cause analytical interpretation errors. Analysts can issue incorrect assumptions when they explain reports and results. For example, a reduction in customer orders during a given month can be awarded to a drop in the marketing budget, while the real reason could be a delay in the availability of the product.

Low data quality

Data consumers may have limited control over the quality and availability of data. They may have to deal with missing or double data, validity questions, a lack of data documentation and other similar problems. Hidden prejudices towards a particular genre, a race, religion or ethnic group can also be present in the dataset.

What are the data sharing technologies ?

There are many technologies that reduce friction between producers and consumers, reduce risks and improve data sharing value. We give some examples below.

Data storage

A data warehouse is a central benchmark to store data from several operational units. Data warehouse architecture consists of different levels. The upper level represents the front customer which displays the results via tools for creating reports, analysis and data exploration. The intermediate level includes the analysis engine used to access and analyze data. The lower level of the architecture represents the database server, the place where the data is loaded and stored. Superior and intermediate level applications can share common data games stored in the lower level.

Data warehouses are useful for sharing internal data. Workloads accessing shared data can be isolated from each other.


An API is a mechanism that allows two software components to communicate with each other using a set of definitions and protocols. The interface can be considered as a service contract between two applications. This contract defines the way in which the two parties communicate through queries and responses. Data sharing APIs support precise access controls and exactly specify what data consumers can request.

Federated learning

Federated learning is a machine learning technology (ML) which allows artificial intelligence systems to train on distributed data games. Data producers retain control while contributing to collaborative technological advances. For example, ML algorithms that detect cancer train on cancer tissue images from various medical institutions.

Blockchain technology ?

Blockchain technology is an advanced database mechanism that allows transparent sharing of information within a business network. A blockchain database stores data in blocks linked together in a chain. The data is chronologically consistent, as you cannot delete or modify the chain without the network consensus. Therefore, you can use blockchain technology to create an unalterable or unchanging register for monitoring orders, payments, accounts and other transactions. In addition, the system has integrated mechanisms which allow both to prevent unauthorized transactions inputs and to create consistency in the shared view of these transactions.

Data exchange platforms

Open data platforms allow different entities to record their datasets for public consumption purposes; You just need to prepare and submit the data. The platform provides the storage and access infrastructure. Anyone can access your data.

How can AWS support your data sharing process ?

When the data is shared on AWS, everyone can analyze it and create services from them using a wide range of calculation and analytics of data. These include Amazon Cloud Compute (Amazon EC2)), Amazon Athena, AWS Lambda, and Amazon Emr. The sharing of cloud data allows your users to spend more time on data analysis than their acquisition. We give some examples of technologies below.

  • Amazon Redshift is a data storage technology that allows instant, granular and fast access to data without having to copy or move them. Your users always see the most recent and consistent information, as they are updated in the data warehouse.
  • Amazon Managed Blockchain is a fully managed service that facilitates the creation and management of scalable blockchain networks and the registry technology distributed.
  • AWS Data Exchange allows you to easily find datasets accessible to the public thanks to the AWS services.
