Step-by-step explanation:
Jamal is looking for software that will enable him to create text documents, prepare presentations, maintain a database, and develop numerical charts for his small business. The best option for Jamal would be integrated software suites that offer a range of applications to cover these needs.

Spreadsheet programs like Microsoft Excel are also mentioned; they are essential for analysing numerical data and developing charts.
