FAQ

The key components of a data warehousing solution include:

- Data Sources: Various sources of operational data, including databases, CRM systems, ERP systems, social media platforms, IoT devices, and external data sets such as market research reports and industry benchmarks
- Data Extraction, Transformation, and Loading (ETL) tools: Software that extracts data from source systems, transforms it into a consistent format, and loads it into the data warehouse
- Database (or Relational Layer on top of a Data Lake): A central repository where transformed data is stored, organized, and managed as relational data
- Data marts: Subsets of the data warehouse tailored to specific business lines or functions
- Analytics & reporting tools: Applications that access the data warehouse for reporting, analysis, and BI
- Data governance and quality management: Processes and policies to ensure data accuracy, consistency, and security.

Our data warehouse consulting services emphasize the importance of each component in creating a robust data warehouse strategy.

A data lake stores vast amounts of raw, unstructured data in its native format.

A data warehouse, on the other hand, holds structured data that has been processed and structured for specific purposes.

A data lakehouse combines the two, offering a way to manage both raw and processed data, supporting diverse analytics and ML in a single, scalable architecture, and allowing businesses to leverage broad data capabilities, from real-time analytics to deep learning, within one platform.

Integrated Planning & Discovery: This phase of data warehouse consulting services establishes a solid groundwork for the project's success. This is achieved by ensuring the alignment of stakeholder expectations and goals with an in-depth examination of the organization’s current tech landscape. Key activities done by data warehouse consultants include identifying business needs, cataloging data sources and connectors, evaluating existing reports and machine learning models, projecting budgetary needs and team structure, assessing the quality of data, and analyzing metrics. This phase culminates in conceptualizing a data warehouse strategy and ETL framework to propose solutions with different tech stacks and develop a prototype.

Development & Testing: Based on the chosen tech stack and defined needs, this phase focuses on constructing a resilient data warehouse. Key tasks involve setting up the database structures and schemas, integrating various data sources, creating ETL processes, conducting data profiling, importing past data records, enforcing data integrity measures, fine-tuning automation processes, and conducting rigorous testing to ensure reliability and performance.

Ongoing Support: This phase involves establishing a dedicated team to provide support services for the data warehouse, encompassing the resolution of issues in compliance with SLA conditions, minimizing expenses related to storage and processing, executing minor improvements, overseeing system operations, and troubleshooting.

To ensure data security and privacy within a warehouse, our data warehouse consulting services include implementing several measures:

- Strict access controls to limit data access to authorized personnel
- Data encryption, both at rest and in transit, to protect against unauthorized access
- Regular security audits to identify and mitigate vulnerabilities
- Adherence to data protection regulations and standards
- Employment of monitoring tools to detect and respond to security threats in real time, ensuring your data remains secure and private

The time to implement a data warehouse solution varies significantly based on the complexity of the data, the technology chosen, the scale of the project, and the specific requirements of the business. Typically, a basic implementation can take a few months, while more complex projects might take a year or more.
Leveraging deep expertise, our data warehouse consulting team ensures rapid project delivery. We streamline every phase, from planning to testing, to exceed expectations efficiently.

Our data warehouse consulting team provides extensive post-implementation maintenance and support, including system monitoring, troubleshooting, updates, user support and training, data quality checks, and adjustments based on feedback and analytics. This ensures your data warehouse remains efficient, secure, and responsive to your business needs

In determining the costs, our data warehouse consulting approach considers several critical factors, including the project's scale, complexity, data integration scope, technology selections, customizations, and security protocols. Our expertise and the project timeline further refine these estimates. The discovery stage offers a more accurate assessment of potential costs. Our data warehouse consultants perform this phase to ensure that clients receive a clear understanding of their investment.
