What are the differences between Access and Oracle? -
I want to know what the differences between access and oracle are.
Interoperability: Access is a small database system that will allow you to create a small-to-medium size database. With minimum security features, Oracle can be integrated with NT security, which gives tight control over who can not and do not allow your data.
Difference: The access is very slow on the network because all processing is done on the client machine, whereas with large DBMSs like Oracle (or SQL Server), you can only query one query (like "SELECT * FROM CUSTIDS WHERE CUSTID = 23 ";), and only the necessary results are returned if you run it in a network with access, all records will be sent to the network, the client will leave the machine to select the necessary records .
Interstate three: If you try to connect more, access actually slows down on the basis of 10 users (based on DB size and how it is being used) Where Oracle can accept hundreds of thousands / simultaneous connections (depending on the server depends on it).
The last major difference is the trigger and stored procedures. Access can not store processes that can be performed remotely. You can write functions and with a little "liver-pokiri" you can get the server side installed in your database or to check the server at pre-determined intervals to execute if the flag is set . With Oracle / (other big DBMSs) you can call stored procedures and they will be executed on command at server side. Triggers are like an Event on an Access form, such as "Post-updates" when you update a record in Oracle, you set the trigger to run processes automatically to check pre-defined rules. Or
