Enterprise Data Warehouse: why business needs a centralized EDW and how it improves efficiency

Digitalization was supposed to make business life easier, but in practice it created new chaos:

• sales data
• advertising
• about customers accumulate in dozens of systems
• disparate files

There is more and more information, and less and less time to process it.

An Enterprise Data Warehouse (EDW) helps regain control: it collects, cleans, and organizes data from different sources - CRM, 1C, Excel, websites, and advertising.

The warehouse performs several important functions: -

Collecting information from different systems. EDW makes it possible to combine data from CRM, 1C, EXCEL, and other important sources. -

Reliable, centralized data storage.

Information is stored in one place, protected, and always available. - Bringing order to the database.

The warehouse removes duplicate documents, corrects errors, and keeps information clean and consistent. - Automated reporting.

This warehouse function saves a great deal of time. - Decision support.

With complete and up-to-date information, company leadership can act quickly and effectively. -

Convenient management of data access.

The warehouse automatically grants users rights to view, edit, and perform other actions with documents. EDWmakes it possible to filter, group, and analyze information.

This is crucial for business owners and project managers striving to make informed decisions.

Understand building an EDW data warehouseeasier with examples.

Imagine a supermarket chain in which each location has its own sales system, accounting and customer database.

Tens or even hundreds of thousands of transactions happen every day.

Before the emergence of data warehouse for businessit used to take painfully long to collect and consolidate transaction data.

Thanks to the development and implementation of a data warehousetransaction data accumulates and is securely stored in a centralized warehouse.

Integrating data from websites, CRM, and ad campaigns into a single platform makes it possible to track the customer journey from a banner click to the target action. Benefits of EDW implementationare obvious even in the short term.

According to some consulting firms, including Oracle and SAP, implementing an EDW can reduce reporting costs by 10-30% while increasing conversion by 10-20%.

Let's look at this scenario using a showroom with an online store and retail sales.

Before the enterprise warehouse was integrated, online and offline sales were tracked separately, there was no unified advertising strategy and no audience segmentation.

Thanks to EDW implementation, in just a few months you can: -

Unify sales, customer and ad campaign statistics in a centralized database.

This makes it possible to see which ads drive sales and drop ineffective ones, reducing costs. -

The showroom sends promotions to specific segments, taking customer requests and interests into account. - As a result, sales increase and conversion rises. -

One of the key Data Warehouse benefitsDataWarehouseis to create a single source of truth.What exactly does this give the business: -

Situations where marketers see one set of sales statistics and the finance team sees a completely different one are eliminated.

When different departments of a company work with the same information (statistics, reports), it eliminates inconsistent actions and their consequences. -

A centralized database reduces the time needed to prepare reports. Processes that previously took many hours or days are fully automated.

A company executive can get detailed statistics on revenue, top-selling products, and low conversion at any time. - Data visualization in business through EDW helps IT departments.

The latter are freed from manually collecting data and editing reporting documents thanks to a single source of information.
