Regardless of the size of your company, chances are you’ve heard of data warehouses, but perhaps are unsure exactly what they are and how your organization can benefit from them. Successful companies all have one thing in common - they make the best decisions based on the data at hand, which usually lead to good business results. A data warehouse is a business intelligence tool designed to manage huge volumes of data from multiple sources. Here’s what you need to know about data warehouses and the advantages they offer for your business.
Data warehouses definedA data warehouse is a centralized store of all data generated by the departments of a large organization. It is specially designed for data analysis, generating reports, and for other ad-hoc queries. A data warehouse extracts the huge streams of data from a company’s operational and external databases and turns them into meaningful data, so business decisions can be made based on this information.
Differences between data warehouses and databasesThe purpose of a database is to record and store current data from users. A database is suitable for the traditional type of data storage method. For instance, a bank ATM uses a database to record their customers’ money transactions in real-time. A data warehouse, on the other hand, is a type of database but specifically designed for data analysis. It is used to store and summarize large volumes of historical data.
Benefits of data warehousesA goal common to all businesses is to make better business decisions than their competitors. Once a data warehouse is implemented into your business intelligence plans, your company can benefit from it in many ways.
- Better decision-making - Corporate decision makers will no longer have to make important business decisions based on limited data and hunches. Data warehouses store credible facts and statistics, and decision makers will be able to retrieve that information from the data warehouse based on their personal needs. In addition to making strategic decisions, a data warehouse can also assist in marketing segmentation, inventory management, financial management, and sales.
- Quick and easy access to data - Speed is an important factor that sets you above your competitors. Business users can quickly access data from multiple sources from a data warehouse, meaning that precious time won’t be wasted on retrieving data from multiple sources. This allows you to make quick and accurate decisions, with little or no support from your IT department.
- Data quality and consistency - Since data warehouses gather information from different sources and convert it into a single and widely used format, departments will produce results that are in line and consistent with each other. When data is standardized, you can have confidence in its accuracy, and accurate data is what makes for strong business decisions.
