课程概述

This is the second course in the Data Warehousing for Business Intelligence specialization. Ideally, the courses should be taken in sequence. In this course, you will learn exciting concepts and skills for designing data warehouses and creating data integration workflows. These are fundamental skills for data warehouse developers and administrators. You will have hands-on experience for data warehouse design and use open source products for manipulating pivot tables and creating data integration workflows. In the data integration assignment, you can use either Oracle, MySQL, or PostgreSQL databases. You will also gain conceptual background about maturity models, architectures, multidimensional models, and management practices, providing an organizational perspective about data warehouse development. If you are currently a business or information technology professional and want to become a data warehouse designer or administrator, this course will give you the knowledge and skills to do that. By the end of the course, you will have the design experience, software background, and organizational context that prepares you to succeed with data warehouse development projects. In this course, you will create data warehouse designs and data integration workflows that satisfy the business intelligence needs of organizations. When you’re done with this course, you’ll be able to: * Evaluate an organization for data warehouse maturity and business architecture alignment; * Create a data warehouse design and reflect on alternative design methodologies and design goals; * Create data integration workflows using prominent open source software; * Reflect on the role of change data, refresh constraints, refresh frequency trade-offs, and data quality goals in data integration process design; and * Perform operations on pivot tables to satisfy typical business analysis requests using prominent open source software...

I liked the quality of lectures. Exceptional meterials to undrstand classic ETL/ELT process in a nutshell. I used this course to get basic knowledge on this thing before an interview.

Great course. It mimics real life case. However, the time required to complete assignments is much more than stated. The assignments are great though, I learned a lot from those.

This course has plenty room for improvement. On one hand, it provides a good understanding of the different data warehousing architectures and design principles, an essential foundation to anyone interested in the field. The material on data integration is also excellent, along with the associated assignment. On the other hand, the peer-graded assignment on data warehousing design is very demanding and isn't clearly described from the lectures and practice problems what the students ought to do to get a perfect grade. Installing the software and getting it to work is also a skill on its own, but it truly is something that a professional will encounter in their work!

Pros: Information is perfect for anyone looking at Business Intelligence as a career field, or already in the career field itself. I found the first week to challenge my on-the-job knowledge of a fuller set of concepts and general terminology.

Cons: The wording on the quiz questions, in some cases, seems much different than the PPT slides and the instructor's language. UPDATE: The wording is a significant challenge, even when advancing into the more complex topics. I have had many differences of opinions on the solutions based on wording in the requirements.

Really short lessons, and usually half of lesson is spent on introduction and talking about what will be in the lesson. Nevertheless, course is focused on theory, rather than the practice. I think it should be more detailed and with more practical assignments.

Well organized lectures but the documentation is full of errors. This in combination with the lack of response on the a lack of responsiveness on the forums might make this class frustrating for some.

This course needs a cleanup of loose ends on some of the assignments. Some assignment requirements are very ambiguous and in some cases the solutions are not matching the requirements of what was due.

Real world data warehouse integrations are more complex than just inner joining the tables to drop those rows not found in the original tables. i wish more complex scenarios are covered.

Assignments are very good, in fact excellent, but the material could be a bit more descriptive. And the practice exercise of assignment 5 had lots of discrepancy with the actual

I think there is still missing purpose on some explanations, for example, in the last assignment there was requested something we never learned during the course.

Some good parts on data integration but the key sections on DW design and in particular the assignment are really poorly written.

Needs serious updates. A lot of good information, but assignments are thrown together, and instructions are often not clear.

It's a good course but it could improve the explanations provided in giving more detail and examples. Give deeper examples!!

An introductory course, gives the very basics on the subject. Lacks in material and (available) references.

This course was full of issues related to the installation and use of Pentaho Pivot 4J and Data Integration. The professor's presence is resolving these issues was practically nonexistent. Coursera needs to do a much better job at insuring that their professors are offering a quality course and living up to the expectations of the students. In the case of this course and the professor, they failed miserably. In addition, it is practically impossible to get support from Coursera when an issue exists and in most cases when contact is made, the assistance is minimal. It is a shame as the platform is nicely designed and the course topics are very interesting. If you are considering taking this course, be forewarned that the majority of the support of problems/issues come from the community, not the Professor or Coursera. In addition, you are required to grade the assignments of your fellow students. This is not done by the professor.

Not enough implication from the instructors in the course. Students are left alone with the material, without any answers to there questions on the course.

Peer review process subject to personal interpretation and leading to frustration for the students.

That's quite unfortunate as this provides a bad experience whereas the course might have been good without that.

The course is very informative, but you have to work with a very slow website for an assignment and you need to install applications which are a lot of hassle and will cost you a lot of time. I still cannot get an application to work to finish the last assignment. Too bad for all the effort I put in so far and very frustrating.

The course lectures were too sparse leading up to the final, very important assignment of learning to how to create an ETL package. More time and energy should have been spent on the technical aspects of the Pentaho Spoon program, rather than doing overviews of application pros and cons.

I think this course is not apropiated for work specialization, is only as light additional knowledge of several concepts without go into details.

I don't recomend it. I have left before finish trial week, because it doesn't reach my expectations.

In module 5 the assignment was not able to pass without looking for further assistance in the web. The knowledge of handling Pentaho integration tool was not good enough explained to pass the assignment. Some steps were really tricky.

Awful. Just awful. There are dozens of students trying to install Pentaho and failing. Only reason I managed is that I have prior experience with the software. There are no TAs, no help, nothing. The Quiz is a scam designed to force you to shell out even more money of the so-called-optional textbook, and the assignments are extremely vague and orders of magnitude beyond the laughable 30 minutes the instructor suggested they should take. My submissions for week 3 total over 30 pages -- and I work a full time job... Avoid this class, do not reward terrible courses with your cash.

No instructor engagement in the course, see the history of posts by the professor. Last in June 2019. The course materials aren't sufficient to complete or understand the material beginning in Module 3. Figuring out how to download the software for the course is very confusing and the documentation is outdated. I would recommend pulling the course from the platform until the instructor(s) become active. I will be removing my monthly payment and don't intend to enroll in future Coursera courses anytime soon.
