Abstract

Principles of the present invention provide a method of entering a default field value in a second data entry field based on a user'"'"'s current entry in a first data entry field. The method establishes a relational index table, the relational index table including at least one record having at least three fields. The fields include: a parent field containing a prior entry in the first data entry field; a child field containing an associated prior entry in the second data entry field; and a frequency field including a count of the number of times the prior entry in the first data entry field was associated with the prior entry in the second data entry field. The method further includes: receiving the user'"'"'s current entry in the first data entry field; and looking up the user'"'"'s current entry in the first data entry field in the parent field of the relational index table and returning the associated prior entry in the child field as the default field value.

Claims

a parent field containing a prior entry in the first data entry field,

a child field containing an associated prior entry in the second data entry field, and

a frequency field including a count of the number of times the prior entry in the first data entry field was associated with the associated prior entry in the second data entry field;

receiving the user'"'"'s current entry in the first data entry field; and

matching the user'"'"'s current entry in the first data entry field to the prior entry in the parent field of the relational index table and returning the associated prior entry in the child field having the greatest count from the frequency field as the default field value; and

automatically entering the default field value into the second data entry field.

2. The method of claim 1, further including:

receiving a keystroke from the user; and

further wherein matching includes looking up the user'"'"'s current entry in the first data entry field in the parent field of the relational index table and returning the associated prior entry in the child field having a first character matching the keystroke received from the user as the default field value.

3. The method of claim 1, wherein the parent field, the child field, and the frequency field am contained in one relational index table.

4. A system for entering a default field value in a second data entry field based on a user'"'"'s current entry in a first data entry field, the first and second data entry fields being separately displayed on a screen, the system comprising:

a memory; and

a microprocessor coupled to the memory and programmed to;

establish a relational index table, the relational index table including at least two records, the records having at least three fields, the fields including;

a parent field containing a prior entry in the first data entry field;

a child field containing an associated prior entry in the second data entry field; and

a frequency field including a count of the number of times the prior entry in the first data entry field was associated with the associated prior entry in the second data entry field;

receive the user'"'"'s current entry in the first data entry field;

match the user'"'"'s current entry in the first data entry field to the prior entry in the parent field of the relational index table and return the associated prior entry in the child field having the greatest count from the frequency field as the default field value; and

automatically enter the default field value into the second data entry field.

5. The system of claim 4, wherein the microprocessor is further programmed to:

receive a keystroke from the user; and

match the user'"'"'s current entry in the first data entry field to the prior entry in the parent field of the relational index table and return the associated prior entry in the child field having a first character matching the keystroke received from the user as the default field value.

6. The method of claim 4, wherein the parent field, the child field, and the frequency field am contained in one relational index table.

7. An article of manufacture comprising instructions for entering a default field value in a second data entry field based on a user'"'"'s current entry in a first data entry field, the first and second data entry fields being separately displayed on a screen, the instructions being capable of causing a processor to:

establish a relational index table, the relational index table including at least two records, the records having at least three fields, the fields including;

a parent field containing a prior entry in the first data entry field;

a child field containing an associated prior entry in the second data entry field; and

a frequency field including a count of the number of times the prior entry in the first data entry field was associated with the associated prior entry in the second data entry field;

receive the user'"'"'s current entry in the first data entry field;

match the user'"'"'s current entry in the first data entry field to the prior entry in the parent field of the relational index table and return the associated prior entry in the child field having the greatest count from the frequency field as the default field value; and

automatically enter the default field value into the second data entry field.

8. The article of manufacture of claim 7, wherein the instructions are further capable of causing a processor to:

receive a keystroke from the user; and

match the user'"'"'s current entry in the first data entry field to the prior entry in the parent field of the relational index table and return the associated prior entry in the child field having a first character matching the keystroke received from the user as the default field value.

9. The method of claim 7, wherein the parent field, the child field, and the frequency field are contained in one relational index table.

10. A method of entering a default field value in a data entry field based on prior entries in the data entry field, comprising:

establishing a frequency index table, the frequency index table including two or more records having at least two fields, the fields including;

a parent field containing a prior entry in the data entry field; and

a frequency field including a count of the number of times the prior entry in the data entry field has been entered through prior entries;

prior to receiving current input in the data entry field from the user, triggering the return of the prior entry in the parent field of one of the records having the greatest count in the frequency field, this returned prior entry being the default field value; and

automatically entering the default field value into the data entry field.

11. The method of claim 10, further including:

receiving a keystroke from the user; and

further wherein returning the prior entry in the parent field includes returning the prior entry in the parent field having a first character matching the keystroke received from the user as the default field value.

12. The method of claim 11, wherein returning the entry in the parent field includes:

finding a record group from the two or more records, the record group having prior entries in the parent field having a first character matching the keystroke received from the user; and

returning the prior entry in the parent field of the record within the record group having the greatest count in the frequency field as the default field value.

13. A system for entering a default field value in a data entry field based on prior entries in the data entry field comprising:
