Daylight Worksheet - Database Loading ...SHOW HINTS

Loading a database means storing data, usually from an existing TDT file, into an already-created database. Several options are available which control merging of TDTs, standardization, and handling of indirect data.

• Loading a database with sthorman -
  1. Launch sthorman and select the databases menu. Select the database you just created and load it with the file test.tdt.

  2. After the load is complete, list the database to a file and compare this saved TDT file with the input file, using tdtcount -VERBOSE TRUE on each file. In this way verify that the data has been stored. Are there any differences in the files? If so, examine them and try to explain why.

• Loading a database with thorload -
  1. thorload requires that all parameters are specified on the command line. Here is an example:

     thorload test < test.tdt


  2. Again list the database, this time with thorlist, and again compare with the input file using tdtcount.
