Sql Training Online Simpledb Download

Disclaimer. I have never taught online. With only 1-week of prep, we were asked to switch to online teaching. I am quickly learning how to do so from trying to figure out how best to deliver content, to how to assess student understanding and work around the many challenges of an online environment. I assume other faculty will be in a similar situation as COVID-19 continues to spread and more countries take precautionary measures such as closing university campuses. Here are the steps I am taking and I hope this blog helps others who are in a similar position and need to teach a Database Systems course. I will also provide the lessons I learn as I go through this.

Pre-online status. We have covered the relational model, relational algebra, SQL, database design, normalization and FDs, and have started the database architecture unit. We had just finished access methods. My lecture style encourages lots of student participation with different in-class exercises. My class has 25 students. Labs (SimpleDB labs) and problem sets can be done in pairs.

My current plan is as follows: (i) Replace the group project with students individually writing 2-3 research paper critiques and responding to at least one other student critique online. (ii) Replacing the midterms with the sub-topic questions that are spread out through out the entire semester. (iii) Keeping the remaining lab and problem set as is. Ultimately, assessment should be in line with your learning objectives and the form of assessment can change as long as you achieve your objectives.

While some tools enable online proctoring, it is difficult to administer midterms online. Finally, it is worth noting that students may be stressed, or worried about family that they may not be able to travel to due to travel restrictions or quarantines, or even sick or in isolation. By distributing the weight of the midterms across many questions for each lesson I hope to not disadvantage students who are dealing with a particularly difficult situation.

This section contains problem sets, labs, and a description of the final project. Some assignments require access to online development tools and environments that may not be freely available to OCW users. The assignments are included here as examples of the work MIT students were expected to complete.

Amazon CloudFront, a cloud-based content distribution network (CDN), is a new offering from Amazon Web Services at the time of this writing. It enables you to place your online content at the edges of the network, meaning that content is delivered from a location close to the user requesting it. In other words, a site visitor from Los Angeles can grab the same content from an Amazon server in Los Angeles that a visitor from New York is getting from a server in New York. You place the content in S3 and it gets moved to the edge points of the Amazon network for rapid delivery to content consumers.
