Spreadsheets (Lotus, Excel,..)
Many companies today use Microsoft Excel, because the Excel for runners of the market disappeared.
The popularity of Excel is shown by the fact, that users can save and edit business data easily organized. Create reports and charts is no problem, in other words the user has relatively simple means to daily operations to follow.
The disadvantage of spreadsheets however is that some data in various spreadsheets double can occur with the result that different users on indefinite times common data can change.
Data integrity is at stake, certain data is no longer reliable. The only way out is: structure in the data. The use of database concepts is an obvious tool.
The use of databases in certain companies on encountering resistance because apparently abstract thinking in tables and relations is not a daily business.
