Stored procedures SPs for short are generally used to simplify certain steps, such as inserting or deleting a data record. For client programmers this has the advantage that they do not have to process the tables directly, but can rely on SPs.
Like views, SPs help in the administration of large database projects. SPs can also increase efficiency. MySQL has supported triggers in a limited form from version 5.
Unicode: MySQL has supported all conceivable character sets since version 4. Full-text search: Full-text search simplifies and accelerates the search for words that are located within a text field.
If you employ MySQL for storing text such as in an Internet discussion group , you can use full-text search to implement simply an efficient search function. Replication: Replication allows the contents of a database to be copied replicated onto a number of computers. In practice, this is done for two reasons: to increase protection against system failure so that if one computer goes down, another can be put into service and to improve the speed of database queries.
Transactions: In the context of a database system, a transaction means the execution of several database operations as a block. The database system ensures that either all of the operations are correctly executed or none of them. This holds even if in the middle of a transaction there is a power failure, the computer crashes, or some other disaster occurs.
Thus, for example, it cannot occur that a sum of money is withdrawn from account A but fails to be deposited in account B due to some type of system error.
Transactions also give programmers the possibility of interrupting a series of already executed commands a sort of revocation. In many situations this leads to a considerable simplification of the programming process. In spite of popular opinion, MySQL has supported transactions for a long time.
One should note here that MySQL can store tables in a variety of formats.

But there are a number of additional formats that do support transactions. The most popular of these is InnoDB, which will be described extensively in this book. Foreign key constraints: These are rules that ensure that there are no cross references in linked tables that lead to nowhere. GIS functions: Since version 4.

The decisive drawback to file-server systems is that when run over a network, they become extremely inefficient as the number of users grows.
