1 Define your goals

The first step in any data warehousing project is to clearly define your goals and expectations. What are the business problems you want to solve? What are the key performance indicators you want to measure? Who are the stakeholders and users of the data warehouse? How will the data warehouse align with your existing data sources, systems, and processes? By answering these questions, you can establish the scope, requirements, and objectives of your project.

For any project , I'd define goals and try to answer questions like: * what is the business problem that we are trying to solve? * What does your resources look like? Is it enough or there's a need of upgradation? * Who are stackholders involved? Are they onboard with your plan and vision of DW project?

2 Choose your architecture

The next step is to choose the architecture and design of your data warehouse. There are different types of data warehouse architectures, such as the star schema, the snowflake schema, the data vault, and the lambda architecture. Each one has its own advantages and disadvantages, depending on the complexity, volume, and variety of your data. You also need to decide whether you want to build your data warehouse on-premise, in the cloud, or in a hybrid model. You should consider factors such as scalability, security, cost, and performance when making these choices.

3 Select your tools

Another crucial step is to select the tools and technologies you will use to build, manage, and access your data warehouse. You will need tools for data integration, data quality, data modeling, data storage, data processing, data analysis, and data visualization. There are many options available in the market, from open-source to commercial, from traditional to modern, from relational to non-relational. You should evaluate the features, functionality, compatibility, and usability of each tool before making a decision.

4 Plan your implementation

Once you have your goals, architecture, and tools in place, you need to plan your implementation strategy and timeline. You should follow a structured and iterative approach, such as the agile or waterfall methodology, to manage your project phases, tasks, resources, and deliverables. You should also define your testing, validation, and deployment procedures, as well as your change management and governance policies. You should communicate your plan to your team and stakeholders, and monitor your progress and performance regularly.

5 Train your users

The final step in your data warehousing project is to train your users on how to use and benefit from your data warehouse. You should provide them with adequate documentation, tutorials, and support to help them understand the data warehouse structure, schema, and queries. You should also teach them how to use the tools and applications that connect to your data warehouse, such as dashboards, reports, and analytics. You should encourage feedback and suggestions from your users to improve your data warehouse quality and usability.

You're about to embark on a new data warehousing project. What do you need to know? Now you have a basic overview of the steps and considerations involved in creating a data warehouse. By following these guidelines, you can increase your chances of delivering a successful and valuable data warehouse for your organization.

I think for a DWH project optimized & scalable architecture and source-to-target mapping play an important role in implementation. Along with it data sources, data profiling to provide clean data techniques to keep DWH accessible & functional, data security are also important in DWH project.
