1。任何人都可以运行查询。插入、更新删除,添加数据,修改数据,删除数据女士很容易的访问。一个人可以把他们的数据归档。假设一个数据是必需的,但需要避免一次,对女士很容易访问。在excel文件插入、更新、删除、添加数据,修改数据,删除数据女士访问是不可能的。我们需要删除的数据行。工厂没有审计表。历史不能。一个人可以把他们的数据归档。假设一个数据是必需的,但需要避免一次,对女士很容易访问。
2。女士的数据抓取工具很容易访问。我们可以使用查询这个活动。后写一个简单的查询我们可以找到连接两个表的数据。我们可以在第二个从表中获取数据。主键检查有女士访问。所以在MS ACCESS数据库数据重复检查是可能的。数据抓取工具并不容易。我们不能用查询这个活动。不可能那么容易女士访问获取连接记录从2表。从表中我们可以卖到很多数据在第二个,但它是一个长时间的工作。主键检查在excel中不可用。所以excel数据库中数据重复检查是不可能的。

1. Anyone can run queries. Insert, update deletes, to add data, modify data, delete data is very easy by MS ACCESS. One can take their data archive. Suppose one data is required but need to avoid for one time, is very easy for MS ACCESS. In the excel file Insert, update delete, to add data, modify data, delete data is not possible as MS ACCESS. We need to remove the data from the row. No audit table facility. History cannot be taken. One can take their data archive. Suppose one data is required but need to avoid for one time, is very easy for MS ACCESS.
2. The data fetching facility is very easy for MS ACCESS. We can use query for this activity. Just after writing an easy query we can find join data from two tables. We can fetch much data from the table within a second. Primary key checking is available in MS ACCESS. So data duplication checking is possible in MS ACCESS database. The data fetching facility is not so easy to excel. We cannot use query for this activity. It is not possible as easy as MS ACCESS to fetch join record from 2 tables. We can fetch much data from the table within a second, but it is a long time job for the first time. Primary key checking is not available in excel. So data duplication checking is not possible in excel database.
