| 1 | 1 | Amber Herold | h1. DB Migration Process |
|---|---|---|---|
| 2 | |||
| 3 | 3 | Amber Herold | The tables that will be affected are in the dbemdata database and the project database. |
| 4 | Migrate the user data from project to dbemdata because dbemdata is already in Sinedon format. |
||
| 5 | 4 | Amber Herold | Eventually, we would like to have 3 databases, appion, leginon and project. The user related tables in dbemdata would be moved to project. |
| 6 | All the tables in project still need to be converted to Sinedon format. |
||
| 7 | 1 | Amber Herold | |
| 8 | +dbemdata+ |
||
| 9 | |||
| 10 | * GroupData |
||
| 11 | * UserData |
||
| 12 | |||
| 13 | +project+ |
||
| 14 | |||
| 15 | * users |
||
| 16 | * login |
||
| 17 | * pis |
||
| 18 | * userdetails |
||
| 19 | * projectowner |
||

| 21 | h2. 1 Add new columns to UserData |
||
| 22 | |||
| 23 | Add: |
||
| 24 | |||
| 25 | * username |
||
| 26 | * fullname |
||
| 27 | * firstname |
||
| 28 | * lastname |
||
| 29 | * password |
||
| 30 | |||
| 31 | |||
| 32 | Leave the existing columns as is. Use of "name" and "full name" (with a space) will be phased out. |
||
| 33 | 1 | Amber Herold | |
| 34 | 3 | Amber Herold | h2. 2 Copy data to the UserData table |
| 35 | |||
| 36 | From users, copy username, firstname, lastname to UserData. |
||
| 37 | From login, copy password to UserData. |
||
| 38 | From userdetails, copy email to UserData. |
||
| 39 | |||
| 40 | h2. 3 Create projectowner table |
||
| 41 | |||
| 42 | Move the data from pis table to a new projectowner table in the project database. This table will refer to users in the UserData table. |
||
| 43 | We will phase out use of the pis table. |
||
| 44 | |||
| 45 | h3. 4 Modify userdetails table |
||
| 46 | |||
| 47 | Remove the email column from the userdetails table. |
