Oracle Tips

The Data Warehouse Development Life Cycle

Data Warehouse Project Tracking
For a data warehouse project, the savvy manager must be able to track the project from many angles while ensuring that the lower-level management produces complete project reporting information.

Let’s start with the obvious. The project manager will need to identify the major tasks that comprise the project implementation and assign time durations, resources, and completion criteria (quality checks) to each major task. For example, consider the task duration table shown in Table 2.4.

TASK ID               TASK_NAME               Duration         Dependencies    Skills Required
101                     Extract Program          79 hours        98, 100             C++ Proficient
102                     Load Program             28 hours        101, 95             VB Proficient
103                     Report Menu Program   19 hours        37                    HTML
104                     Report Program           49 hours        98,                   101 C++ Proficient

Table 2.4 A task duration table.

Here, you can see how this collection of tasks, resources, times, and dependencies can be collected and graphically displayed. As mentioned earlier, there are two major ways to display project information: PERT and CPM.
