1. New approaches to Materials Education - a course authored by Mike Ashby and David Cebon, Cambridge, UK, 2007 © MFA and DC 2007 Unit 12. Using CES in research: editing and creating databases

2. © MFA and DC 2007 Outline: CES Constructor Constructor lets you Edit a record Add a new record Add new fields to a record Create entirely new databases, on which the search engine operates Definitions A Database contains one or more Data-tables A Filter limits the records that can be accessed A Form formats the screen display and printout of a record Records in one table are related to those in another by Links

17. © MFA and DC 2007 Take-home exercises: editing a database 12.1 Edit data-error in Trial database  Open Trial database in CES – observe data error in Aluminum record (Density factor 1000 too small).  Open Trial database in Constructor. Double click on MaterialsUniverse to open  Locate Aluminum on tree  Correct Density to 2500 – 2900 kg/m 3

18. © MFA and DC 2007 Take-home exercises: adding a new record 12.2 Add a record for the amorphous alloy Vitraloy 1  Open Trial database in Constructor. Double click on MaterialsUniverse to open, as in Exercise 6.1  Right-click on MaterialsUniverse and select New Record  Name the record Vitraloy 1, select a color and insert the record into all filters  Insert data Name – Vitraloy 1 Image – copy from file Density 6100 – 6200 kg/m 3 Price 17 – 29 $/kg Young’s modulus100 – 105 GPa Yield strength 1740 – 1760 MPa  Insert links to ProcessUniverseDie casting ReferencesASM metals handbook  Close Constructor and open Trial database in Selector to check that record exists and contains the data

19. © MFA and DC 2007 Take-home exercises: adding a new field 12.3 Add a new field to materials records: Flexural strength  Open Trial database in Constructor. Double click on MaterialsUniverse to open, as in Exercise 6.1  From Database in File menu open Table properties / Attributes  Insert New attribute:Flexural strength TypeRange UnitsMPa (Apply / OK)  Insert Image (on disk) (must be BMP format, about 10 x 10 cm)  Insert the new field into the Form: Click on Database / MaterialUniverse / Forms Open Forms / Right click Edu Level 1 / Edit form Find Flexural strength in right hand box / Add to Form Move it through form with Move up / Move down  All records now have a new field Flexural strength MPa
