| 20 | 6 | Amber Herold | Future: |
| 21 | 5 | 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. |
| 22 | All the tables in project still need to be converted to Sinedon format. |
||
| 23 | 2 | Amber Herold | |
| 24 | h2. 1 Add new columns to UserData |
||
| 25 | |||
| 26 | Add: |
||
| 27 | |||
| 28 | * username |
||
| 29 | * fullname |
||
| 30 | * firstname |
||
| 31 | * lastname |
||
| 32 | * password |
||
| 33 | |||
| 34 | |||
| 35 | Leave the existing columns as is. Use of "name" and "full name" (with a space) will be phased out. |
||
| 36 | 1 | Amber Herold | |
| 37 | 3 | Amber Herold | h2. 2 Copy data to the UserData table |
| 38 | |||
| 39 | From users, copy username, firstname, lastname to UserData. |
||
| 40 | From login, copy password to UserData. |
||
| 41 | From userdetails, copy email to UserData. |
||
| 42 | |||
| 43 | h2. 3 Create projectowner table |
||
| 44 | |||
| 45 | 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. |
||
| 46 | We will phase out use of the pis table. |
||
| 47 | |||
| 48 | h3. 4 Modify userdetails table |
||
| 49 | |||
| 50 | Remove the email column from the userdetails table. |
