Hotspot Question
You are developing an app that allows users to query historical company financial data.
You are reviewing email messages from the various stakeholders for a project.
The message from the security officer is shown in the Security Officer Email exhibit below.
TO: Database developer
From: Security Officer
Subject: SQL object requirements
We need to simplify the security settings for the SQL objects. Having a assign permissions at every object in SQL is tedious and leads to a problem. Documentation is also more difficult when we have to assign permissions at multiple levels. We need to assign the required permissions at one object, even though that object may be obtaining from other objects.
The message from the sales manager is shown in the Sales Manager Email exhibit below.
TO: Database developer
From: Sales Manager
Subject: Needed SQL objects
When creating objects for our use, they need to be flexible. We will be changing the base infrastructure frequently. We need components in SQL that will provide backward compatibility to our front end applications as the environments change so that do not need to modify the front end applications. We need objects that can provide a filtered set of the data. The data may be coming from multiple tables and we need an object that can provide access to all of the data through a single object reference. This is an example of the types of data we need to be able to have queries against without having to change the front end applications.
The message from the web developer is shown in the Web Developer Email exhibit below.
TO: Database developer
From: Web Developer
Subject: SQL Object component
Whatever you will be configuring to provide access to data in SQL, it needs to connect using the items referenced in this interface. We have been using this for a long time, and we cannot change this from end easily. Whatever objects are going to be used in SQL they must work using object types this interface references.
You need to create one or more objects that meet the needs of the security officer, the sales manager and the web developer.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
