What Is Data Warehousing?


What Is Data Warehousing?

Data warehouses collect information from multiple sources to provide a single source of truth for analytics processing. They are subject-oriented, integrated, and time-variant.

The process of funneling data into a data warehouse is known as ETL. This includes identifying which data is needed and establishing a process for collecting it.

Business Intelligence

Business intelligence (BI) technologies transform raw data into actionable insights that enable companies to maximize operational efficiency, strategic profitability and increase revenue. The BI suite includes reporting tools that help stakeholders view the business performance, analyze the results of various business processes and track the progress in real time.

The BI tools include dashboards, reports and data visualizations to provide users with a better understanding of data that they can then take actions on. Ultimately, the goal of a business intelligence tool is to enable relatively non-technical end users to make decisions with the help of information.

Business Intelligence is used in many different sectors including banking, retail and healthcare where it can be helpful for analyzing customer patterns or tracking market trends. It is also useful for managing the flow of goods and services in an organization. Business Intelligence and Data Warehousing are interdependent systems that work together to provide quality insights and analysis.

Data Integration

As your business grows and new systems are implemented, integrating data becomes increasingly important. For example, loan officers must review account records, credit histories and property values before approving mortgages, while financial traders monitor incoming streams of market data from internal and external sources. Plant managers depend on a mix of sensors and data from their own operations to monitor the health of pipelines and other equipment.

These diverse data sets need to be consolidated into a usable format for analytics applications. This is what data integration is all about, and it involves a number of steps such as ETL mapping, ELT processing and data cleansing. The unified view created by these processes makes it possible for data analysts to elevate your business intelligence.

Data Warehousing Software

The warehouse allows business users to analyze data across multiple sources and time periods in a single place. This can reveal patterns of information that help business departments make more informed decisions about their operations and products.

A 3NF-designed database often requires a lot of joins to retrieve data, which can slow down query and report responses. A warehouse can provide a new design to reduce these performance challenges.

When selecting a warehouse software, consider its ability to connect with other software your business uses for analysis and reporting. Some solutions require custom integrations that can add cost and complexity to a project. Others support common API connections that simplify the process.

Look for a solution that supports ELT (extract, transform, and load) in the warehouse itself. This eliminates a separate tool for data transformation and simplifies the integration process. Also, check the warehouse’s data latency options. Some offer access to real-time data while others are designed for stability, allowing you to perform ETL at off-hours to minimize impact on data analysis and reporting.

Data Warehouse Architecture

Data warehouse architecture is a process of integrating diverse information into a central database. This includes transforming and loading data, and it aims to make the data easier to access and understand. It also makes sure that data has a consistent format. This includes naming conventions, measurement of variables, and encoding structures. It also ensures that old data doesn’t get erased when new information is added.

A modern business intelligence platform will streamline these workflows so that everyone, from analysts and engineers to BI users, can do their jobs more effectively. It will provide users with the ability to create queries via drag and drop, build stunning data visualizations, and easily generate reports without having to rely on complex programming languages or lengthy SQL processes.

A data warehouse consists of three layers: the top layer, middle tier and bottom tier. The bottom tier is a relational database server that stores the data. The middle tier is an OLAP server that provides users with an abstract view of the data. The top tier is an application layer that contains front-end tools for querying and reporting. It also has metadata repositories that store information about the data. This information includes both business metadata that augments the data with context and technical metadata that describes how to access the data based on its location.
