Part 1: Project Management

The following questions all describe specific problematic project management situations, and ask you how you'd deal with them.

1. Estimations and Timelines

You have recently joined a software team and have been asked to provide project management guidance. The team consists of four developers, and is quite well "gelled". To date, the team has been following a Kanban & Release Train style approach to completing tasks. They are reasonably productive, and project stakeholders are generally happy with the team's output.

1. Voting

Each voter can vote in zero or more referenda. Each referendum has one or more questions, and each question is a yes/no vote. Write the simplest normalized schema to describe this in generic SQL statements or as an entity-relationship diagram. Point out where the indexes would be if you want to quickly know the results of a given referendum question, but you never expect to query a single voter's voting record.

2. Cursors

Explain the difference between explicit and implicit cursors in PL/SQL. Give an example in which an explicit cursor can be used to solve a problem that cannot be solved (or cannot be solved easily) using implicit cursors.

What operational difficulty or complexity, if any, is added as you go from (a) to (b) to (c)?
