Be accurate. As you enter each record, compare the on-screen data to your original documents to verify its accuracy.
Be consistent with grouping terms. Use the same set of terms for fields that might be used to group your data. Suppose you plan to group your household inventory by categories such as jewelry, furniture, appliances, and electronics. You must then enter "jewelry" -not "jewels"-in the Category field for your diamond ring.
Use consistent capitalization. Most database software is case sensitive. Be aware that if you enter "Microwave oven," case-sensitive database software will not find anything when you later search for "microwave oven."
Make sure your spelling is correct. If you misspell an item-such as "portable jakuzi"-when you add it to the database, you won't be able to find it if you later search for "portable Jacuzzi."
Use abbreviations consistently. To your database software, "TV" and "T.V." are completely different.
Be careful about symbols. The telephone number (906) 227-1000 is not the same as 906.227.1000.
