In today’s world, Data is everything. Have you ever wondered what the teams at your company are doing? To watch out for and assess the performance of a company periodically, we need data. But what if there is not enough proper data to analyze? This is when Data Warehousing acts as a lifeline for organizations.
Before delving deeper into Data Warehousing, first let’s understand what is a Data Warehouse, what are its components, and what characteristics it possesses. Similar to a warehouse which is used for storing raw materials and goods, a Data Warehouse is nothing but a centralized location where all your enterprise data like your desperate database system and file system get stored for further analysis.
Data Warehousing is the process of collecting and managing data from multiple sources and storing it in a single, centralized repository. It is used to store large amounts of historical data, which can then be used for business analysis and decision-making. It allows companies to have a unified view of their data which can help them understand current trends and make better decisions.
The company's workflow is maintained by several teams, including HR, Development, Testing, Designing, Marketing, and Sales. If anything goes wrong such as a poorly performing marketing campaign or a slow sales month, then how can a company identify where they are lagging? To resolve this issue, it may be necessary to have a better understanding of each stage of the process by identifying steps that need to be modified and by figuring out which ones are working well.
Data Warehousing facilitates the gathering, analyzing, tracking, and evaluating of data from business processes. As opposed to Database, which is intended to record data, Data Warehousing is intended to analyze data. One can access data from different sources in a single place called a Data Warehouse which saves time in retrieving data. Identifying the places where they are falling behind, helps them to predict future trends in advance.
By collecting data from multiple sources such as customer surveys, web analytics, point-of-sale transactions, and social media, Data Warehousing works around various sectors. The whole data Warehousing process can be divided into three different stages. The following processes make up the normal workflow of a data warehouse.
At this stage, data which is in its raw form is collected from the source system and stored in a layer called a staging layer. And this process is done by the ETL method which involves extraction, transformation, and loading of the data. There are various tools to enable ETL for a Data Warehouse but it is done by following the steps listed below.
Extracting data from various source systems such as relational databases, transaction systems, and flat files.
Transforming the data into a consistent format that can be stored in the data warehouse. This may involve cleansing the data, combining data from various sources, and aggregating data.
Data loading involves the process of packing up all the data and moving it to a specific Data Warehouse.
Data that has been transformed to a warehouse format is put through steps like consolidation and summarizing to make it simpler and more organized to utilize. More data is uploaded to the warehouse over time when sources are updated.
The final step is to analyze the kind of data we want which has come from the disparate systems in their raw form. Transformations can be done at this state to shape the data in a form in which businesses can draw some useful insights from it.
Along with ETL tools, metadata, and access tools, still other components comprise a typical Data Warehouse. These parts are all designed to work rapidly so you may examine data as it goes and receive results quickly.
The structure of the Data Warehouse is built on a database that is used to help manage warehouse operations and ensure efficient workflow. Warehouse Database is specifically designed to store and track data that can be used for future analysis. Some of them include Cloud-based, Typical, and Analytics Database.
ETL tools remain the core elements of the Data Warehouse. They aid in extracting data from multiple sources and transforming and loading it into the Data Warehouse. Other functions like filling and distributing data from the central repository to Business Intelligence apps are also possible.
Metadata describes a set of data and can include information such as the name of the data set, its size, its format when it was developed, who developed it, and any other relevant information. It helps to ensure that data is used correctly and is accessible to people who need it.
Using access tools, users can interact with the data in your data warehouse. Access tools include data mining, Online Analytical Processing, query, and reporting tools, and application development tools. Companies that employ data warehouses typically can't deal with databases without the aid of tools unless they also have access to database administrators.
The BI interface or BI database architecture can be accessed by end users through the reporting layer in the data warehouse. The data warehouse's reporting layer serves as a dashboard for data visualization, generates reports, and extracts any necessary data.
It is one of the essential elements of a data warehouse. The warehouse bus, which has a data mart, depicts the data flow in a data warehousing bus system. It is a level that facilitates data transmission and is also used to separate data created for a certain group.
Data warehousing can be used for many things, including reporting, analytics, and decision-making. Although there are many different types of data warehouses, each type has distinctive characteristics and uses. Here are a few of the most common forms of data warehouses.
Enterprise Data Warehouse is designed to support the entire organization and is typically used for strategic decision-making. It is usually centralized and allows data from multiple sources to be accessed and analyzed. It is often used for reporting, analysis, and integration with other systems. No matter where the data comes from or which team or department will use it, an enterprise data warehouse is used to store and report all of a company's data.
An Operational Data Warehouse helps to support specific business operations, usually on a daily or weekly basis. It connects to numerous data sources and collects information at one location. In most cases, a real-time operational data store stores and processes data. It is used for transaction processing and the integration of data from multiple sources.
Data Mart is a specialized type of Data Warehouse that concentrates on one topic or area of business. It is used to store and analyze data related to a specific business sector. Users can access data and discover insights more quickly when using a data mart since they don't have to spend time manually combining data from several sources or searching inside a more complicated data warehouse.
