One of the biggest benefits of using a relational database system like Ms Access relates to the ease with which data can be accessed and modified. Typically this is achieved with the help of queries which can glean relevant information from a huge data repository. In other words queries can give you a truncated view of the entire database, with only the relevant records getting showcased. Queries can also be used to perform a variety of actions such as updating data or deleting records when needed. In Ms Access you can create queries in the design view or even write your own queries in SQL. Once queries are created, they can be saved for quick access. In Ms Access several handy queries are present that can help you quickly access and manage your data. Let’s look at some of them.
Append Query for housekeeping tasks
If you are running a line of business application on an Ms Access database, very soon your database would start to fill up. Given the size limitations of the database you would need to archive data or even remove older entries. Both these activities can be achieved with the help of the append query which comes rather handy for housekeeping tasks.
Create a specific table with restricted data with the Make table query
Often you may need to create a new table from the existing data present in the Access database. With the Make table query you would be able to generate a custom table containing the relevant data that you wish to showcase. Once such a table is created you can study it in isolation or even export it to Excel for analysis
Filter and Count data with Crosstab Query
When you are looking perform advanced filtration and counting activities on data stored in an Access database the Crosstab Query is the one you should execute. It effectively functions like a Pivot table and can dig out information from a bloated table within no time.

Every other application in use today is known to throw out error messages and it is hardly a surprise that Ms Access too is prone to errors. However ignoring error messages in Ms Access can be risky as they may be pointers to major issues. Some errors like internal errors or bad file mode can cause a MDB file corruption and compromise your stored data.
