What you would learn in Designing a Data Warehouse course?
Data warehouses are essentially a source of data that can make better-informed decisions. The data is pushed into a warehouse through transactional systems, relational databases, and other sources, usually at a regular interval. Data engineers, business analysts, data scientists, and decision-makers have access to the data using business intelligence (BI) tools, SQL clients, and other analytics tools.
Analytics and data have become vital for businesses to stay ahead of the competition. Business users depend on dashboards, reports, and analytics tools that help them extract information out of their information, track business performance and assist in the decision-making process. Data warehouses are the basis for these dashboards, reports as well as for analytics software by efficiently storing data to reduce data inputs and the outputs (I/O) in data. They also provide query results in a short time to thousands and hundreds of users simultaneously.
A data warehouse is made for data analytics that involves reading vast volumes of data to discover patterns and relationships within the data. A database is utilized to record and store information, like recording the details of transactions.
This course explains the design of dimensions tables—the physical and logical layout of the data warehouse.
The physical design process is the design of the database by using SQL statements. In designing physical, you convert the data collected during the design phase of logical thinking into an outline of the physical structure of the database. Physical design decisions are determined mainly by query performance and aspects of maintaining the database.
An approach to logical designing involves organizing data into a sequence of logical connections, referred to as attributes and entities. An entity represents a block of data. For relational databases, the term "entity" typically corresponds to tables. An attribute is a part of an entity that can help determine the uniqueness of an entity.
The dimension table can be described as the schema of a star in the data warehouse—dimension tables store dimensions or attributes, which define the objects within the table of facts. In data warehouses, it is defined as an information source regarding a specific event.
