I have a project to do in database programming in .NET. Can someone help me, please?opening the file and selecting the EDIT mode. However, in a multiuser system, security must be administer and audit trails. It is must be programe. Reports provide details and summaries in a more. This is to elaborate fashion than queries. Reports have page and column headers and can be sort into order by multiple fields; for example, city within county within state. Once a report description has been compose, it can be save for use again.
From time to time, it is necessary to add or delete fields, or change their lengths or possibly their names. This function is similar to creating the record structure in the first place, except that only modifications are made.
Browse an entire file or select records. Selected records are usually created as a temporary file that can be sorted into a different sequence and, after viewing, can be deleted or saved for later use.
The ease with which a query can be composed determines how often users ask their own questions versus relying on IT staff. For example, retrieving data from two files, such as customers and orders, or vendors and purchases, requires knowledge of how to link the files for the query. Most database programs have a JOIN function, which creates a new file with data from two existing files. Once a query has been composed, it can be saved for use again.
