Data Platform Architecture

Understanding and interpreting data is just the beginning of a long journey, as the information goes from its raw format to fancy analytical boards. A data pipeline is a set of technologies that form a specific environment where data is obtained, stored, processed, and queried. Data scientists and data engineers are part of the data platform.

We will go from the big picture to the details. Data engineering is a part of data science and involves many fields of knowledge. Data science is all about getting data for analysis to produce useful insights.

The data can be used to provide value for machine learning, data stream analysis, business intelligence, or any other type of analytic data. The role of a data engineer is as versatile as the project requires them to be. It will correlate with the complexity of the data platform.

The Data Science Hierarchy of Needs shows that the more advanced technologies like machine learning and artificial intelligence are involved, the more complex and resource-laden the data platforms become. Let's quickly outline some general architectural principles to give you an idea of what a data platform can be. There are three main functions.

Provide tools for data access. Data scientists can use warehouse types like data-lakes to pull data from storage, so such tools are not required. Data engineers are responsible for setting up tools to view data, generate reports, and create visuals if an organization requires business intelligence for analysts and other non-technical users.

Database Architectures

Database architects work closely with software designers, design analysts and others to create databases that may be used by hundreds, if not thousands, of people.

Launch of the Skills for Jobs Database

The Skills for Jobs Database was released at a launch event in Paris. The JP Morgan Chase Foundation supported the development of the Skills for Jobs Database. It is a new tool that can be used to gainsight into what skills are needed in the labour markets and where skill shortages are emerging.

The JP Morgan Chase Foundation supported the development of the Skills for Jobs Database. It is a new tool that can be used to gainsight into what skills are needed in the labour markets and where skill shortages are emerging. The launch of the new database is accompanied by a new website that makes it easier for all audiences to access the database.

The website allows the user to navigate the labour market information available at the occupational level to understand what skills are needed to move from occupations in surplus to others for which there is strong labour market demand. The European Commision, the European Centre for the Development of Vocational Training and the European General for Employment, Social Affairs and Inclusion brought Skills Panorama to you. The European Commision is responsible for steering the Skills panorama in line with EU policy objectives while Cedefop is responsible for the technical development of the site.

BLS: A Survey of Employment and Wage Data for Various Sectors

Workers are classified into occupational categories based on their skills, education, training, and credentials. There are two examples of occupations. Many occupations are found in a large number of industries, but some are found in just one or two industries.
