| <Text>Introduction</Text> |
| <Text>Scientific methodology in the database field can</Text> |
| <Text>provide a deep understanding of DBMS query</Text> |
| <Text>optimizers, for better engineered designs.</Text> |
| <Text>Few DBMS-centric labs are available for scientific</Text> |
| <Text>investigation; prior labs have focused on networks</Text> |
| <Text>and smartphones.</Text> |

| <Text>Demonstration</Text> |
| <Text>Step 1: Choose a labshelf, add a user, and create a notebook,</Text> |
| <Text>a paper, and a study in the paper on the Observer GUI.</Text> |
| <Text>Step 2: Load an experiment specification into the notebook.</Text> |
| <Text>Step 3: Schedule an experiment run on a particular DBMS.</Text> |
| <Text>Step 4: Monitor the run status via Observer, a web app, and a</Text> |
| <Text>mobile app, and wait for the experiment to be done.</Text> |
| <Text>Step 5: Add the completed experiment run to the study and</Text> |
| <Text>conduct a timing protocol analysis for the study.</Text> |
| <Text>Step 6: Produce LaTeX/PDF documents containing the analysis</Text> |
| <Text>results.</Text> |
