SSAS: Supercharge your business intelligence
SSAS (SQL Server Analysis Services) is a powerful business intelligence tool from Microsoft that allows organisations to analyse vast amounts of data and gain valuable insights. It enables the creation of multidimensional cubes, tabular models, and data mining structures, providing a robust platform for data analysis, reporting, and forecasting. Hiring a skilled SSAS freelancer can unlock the potential hidden within your data, empowering you to make data-driven decisions and achieve your business objectives.
What to look for in an SSAS freelancer
Finding the right SSAS freelancer requires careful consideration of their skills and experience. Look for candidates with a strong understanding of data warehousing concepts, dimensional modelling, and ETL (extract, transform, load) processes. Proficiency in MDX (Multidimensional Expressions) and DAX (Data Analysis Expressions) is crucial for querying and manipulating data within SSAS. Experience with various SSAS versions, including multidimensional and tabular models, is also essential.
Main expertise areas to inquire about
When interviewing potential SSAS freelancers, delve into their expertise in these key areas:
- Data modelling: Assess their ability to design and implement effective dimensional and tabular models.
- MDX and DAX: Evaluate their proficiency in writing complex queries and calculations.
- ETL processes: Determine their experience with data integration and transformation using tools like SSIS (SQL Server Integration Services).
- Performance tuning: Inquire about their ability to optimise SSAS solutions for speed and efficiency.
- Data visualisation: Explore their experience with reporting tools like Power BI and Excel, which often integrate with SSAS.
Relevant interview questions
Here are some questions to help you assess the skills of potential SSAS freelancers:
- Describe your experience with different SSAS versions (multidimensional, tabular).
- Explain your approach to designing a dimensional model for a specific business scenario.
- Provide an example of a complex MDX or DAX query you have written.
- How do you approach performance tuning in SSAS?
- What are your preferred data visualisation tools to use with SSAS?
Tips for shortlisting candidates
- Shortlisting should focus on candidates who demonstrate a clear understanding of your business needs and possess the technical skills to address them.
- Review their portfolios for relevant projects and check for client testimonials.
- A strong understanding of data warehousing principles and experience with similar projects to yours are key indicators of a good fit.
Potential red flags to watch out for
Be wary of candidates who lack a deep understanding of data modelling or struggle to articulate their approach to problem-solving. A lack of experience with relevant tools and technologies, or an inability to provide concrete examples of their work, should also raise concerns.
Typical complementary skills
SSAS expertise often goes hand-in-hand with other skills, such as:
- SQL Server database administration
