If your business depends upon the completeness, accuracy, security, and integrity of your data, then opt for a reliable client-server database engine such as Microsoft SQL Server or Oracle.
Do not be misled by false claims of client-server reliability when the database is built using a desktop "shared-file" database architecture, such as that offered by Microsoft Access. Microsoft Access is suitable for very small workgroups only. On a busy network it is highly susceptible to database corruption.
We know Access well and use it often but never for anything mission-critical; it does well as quick query tool on relatively small datasets, and because it supports "heterogeneous joins" it is good for working with data kept in more than one database, e.g. creating a query that connects data in Oracle to an Excel spreadsheet.
