For each question, it offers steps to formulate an effective answer and provides examples of answers that highlight qualifications and lessons learned.
These are the slides from my talk at Data Day Texas 2016 (#ddtx16).
The world of data warehousing has changed! With the advent of Big Data, Streaming Data, IoT, and The Cloud, what is a modern data management professional to do? It may seem to be a very different world with different concepts, terms, and techniques. Or is it? Lots of people still talk about having a data warehouse or several data marts across their organization. But what does that really mean today in 2016? How about the Corporate Information Factory (CIF), the Data Vault, an Operational Data Store (ODS), or just star schemas? Where do they fit now (or do they)? And now we have the Extended Data Warehouse (XDW) as well. How do all these things help us bring value and data-based decisions to our organizations? Where do Big Data and the Cloud fit? Is there a coherent architecture we can define? This talk will endeavor to cut through the hype and the buzzword bingo to help you figure out what part of this is helpful. I will discuss what I have seen in the real world (working and not working!) and a bit of where I think we are going and need to go in 2016 and beyond.
AWS re:Invent 2016: Best Practices for Data Warehousing with Amazon Redshift ...Amazon Web Services
Â
Analyzing big data quickly and efficiently requires a data warehouse optimized to handle and scale for large datasets. Amazon Redshift is a fast, petabyte-scale data warehouse that makes it simple and cost-effective to analyze all of your data for a fraction of the cost of traditional data warehouses. In this session, we take an in-depth look at data warehousing with Amazon Redshift for big data analytics. We cover best practices to take advantage of Amazon Redshift's columnar technology and parallel processing capabilities to deliver high throughput and query performance. We also discuss how to design optimal schemas, load data efficiently, and use work load management.
The seminar is about Data warehousing, in here we are gonna discuss about what is data warehousing, comparison b/w database and data warehouse, different data warehouse models.about Data mart, and disadvantages of data warehousing.
Data Warehouse Design and Best PracticesIvo Andreev
Â
A data warehouse is a database designed for query and analysis rather than for transaction processing. An appropriate design leads to scalable, balanced and flexible architecture that is capable to meet both present and long-term future needs. This session covers a comparison of the main data warehouse architectures together with best practices for the logical and physical design that support staging, load and querying.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
Â
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
Â
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

3. What have you learned from mistakes on the Data warehouse field?
a. Answer tips
Here you have to come up with something or you strain
credibility. Make it small, well intentioned mistake with a
positive lesson learned. An example would be working too
far ahead of colleagues on a project and thus throwing
coordination off.
Everyone makes mistakes, of course, but some companies
are more willing to learn from them than punish those
involved.
Youâve learned that when you do make mistakes, someone
is usually disappointed in the choice you made, but you have
to figure it out for yourself, they might help you decide what
âs right and what âss wrong, but youâll be the decider on
which you choose. Youâve learned that people do care about
you, and to not do it again if you donât want to.
b. Answer samples
Every one makes mistakes but only few people can realize
there mistakes and they donât want to repeat those mistakes
againâŚ.. I am the one in those few people, I donât want to
repeat the mistakes which had done by me in my job/work.

improvement. Have some good ones handy to mention.
⢠Employers look for applicants who are goal-oriented. Show
a desire for continuous learning by listing hobbies non-work
related. Regardless of what hobbies you choose to
showcase, remember that the goal is to prove self-
sufficiency, time management, and motivation.
b. Answer samples
⢠Every should learn from his mistake. I always try to consult
my mistakes with my kith and kin especially with elderly and
experienced person.

10. Interview questions and answers- Page 10
7. What is your greatest weakness?
Ways to answer:
a) First way: Turning your strong point into weak point.
For example: I am a perfectionist and therefore, I rarely
believe in anyone who can work as well as me. As a result, I
am afraid to delegate important tasks to others.
This approach has a weak side as that if you are not clever,
you will cause the employer to believe that you are cheating
him.
b) Second way: Solving your weakness absolutely.
A better approach is that you state one point which was once
your weakness, but you have done well to resolve it.
For example: I tended to be a perfectionist, therefore I didnât
like to delegate to others. But I have found out that in order
to develop the organization, everyone in the organization
must be experienced with many tasks and this is very good
for an efficient team work.
11. Interview questions and answers- Page 11
8. What do you know about this organization?
This question is one reason to do some research on the
organization before the interview. Find out where they have
been and where they are going. What are the current issues
and who are the major players?
Sample answers:
a. A good organization with perfect management. I heard that in
this organization i can gain knowledge and good atmosphere.
b. If its for a good renowned company then its better to go
through the company website and know whatâs the company
profile and whatâs their achievements/successes and branches
& other details.
c. According to me this is one of the best company. It has a
good Environment, We feel good working in companies, which
has good growth in the IT Industries. This Organization has all
the qualities like good growth, good Environment, maintaining a
best level in the IT Industries, etc.
