MySQL

list data file
log database file

in sql commit is used for saving the changes made in database and roll back is to roll back them , changes will not get saved in the database

The INSERT command in MySQL allows you to enter a new row of data to a table in your database.

The same way you insert 1 row, just 10,000 times.

There are two choices, I'm going to assume you've already connected to mysql and you are prepared to run your query:

1. Transactional method:

$query = "INSERT INTO foo (column) VALUES (row1), (row2), (row3) ... (row10000);";

mysql_query($query);

This is ideal when it is imperative that all rows go into the database. Keep in mind that this method will tie up the database until the entire query is completed.

2. Separate queries

$query = "INSERT INTO foo (column) VALUES (row1); INSERT INTO foo (column) VALUES (row2); ... INSERT INTO foo (column) VALUES (row10000);";

mysql_query($query);

This method will allow other queries to run along side and will not necessarily tie up the database, if it's ok if some rows fail this method is probably ideal.

Yes, use a INSERT statement.

ex: INSERT into person_table (id, first_name, last_name) VALUES (1, 'Fred', 'Flintstone');

as a web designer I highly recommend it

no. a new table does not exist after a join command. All that is doing is temporarily pulling the data from the tables. If this command was one that you would want to do often, you can create a VIEW, which is a virtual table. It is an object that pulls data from one or more tables based on your search criteria.

From Database Systems: Design, Implementation, and Management 10th Ed - Coronel / Morris / Rob - 1.3.1 Role and Advantages of the DBMS:

The DBMS serves as the intermediary between the user and the database. The database structure itself is stored as a collection of files, and the only way to access the data in those files is through the DBMS. Figure 1.2 emphasizes the point that the DBMS presents the end user (or application program) with a single, integrated view of the data in the database. The DBMS receives all application requests and translates them into the complex operations required to fulfill those requests. The DBMS hides much of the database's internal complexity from the application programs and users. The application program might be written by a programmer using a programming language such as Visual Basic.NET, Java, or C#, or it might be created through a DBMS utility program.

you can try but you need some serious computer code skills

One can find more information about the php mysql tutorial on Tutorials Point, Tizag, and W3 Schools. More information about the php mysql tutorial can be found at Site Ground.

Data types

First Normal Form: Remove the repeating groups in a table

Second Normal Form: Remove partial dependencies

Third Normal Form: Remove transitive depedencies

3NF is where data depends on nothing but the whole key. It seems that every 3NF table should be in BCNF, as BCNF is stricter than 3NF. But, BCNF requires that every nontrivial attribute is a superkey, even if the dependent attributes are part of keys, that is, when X->Y, X is a superkey for the relation, where 3NF also allows that Y is a key attribute for the relation.

Mysql is not really an open source database. In order to access the database and make modifications, the user must buy the license. True open source would be available to all.

Nested Transactions are transactions within transactions and are currently not supported by MySQL. Nested Transactions are not even vaguely related to Co-related Queries.

The ANSI-SPARC Architecture (American National Standards Institute, Standards Planning And Requirements Committee) is an abstract design standard for a DBMS, first proposed in 1975. Most modern commercial DBMS are based on this system. The ANSI-SPARC model never became a formal standard. The objective of the three-level architecture is to separate the users' view(s) of the database from the way that it is physically represented. This is desirable since: * It allows independent customised user views. ** Each user should be able to access the same data, but have a different customised view of the data. These should be independent: changes to one view should not affect others. * It hides the physical storage details from users.

** Users should not have to deal with physical database storage details. They should be allowed to work with the data itself, without concern for how it is physically stored. * The database administrator should be able to change the database storage structures without affecting the users' views. ** From time to time rationalisations or otherchanges to the structure of an organisation's data will be required. * The internal structure of the database should be unaffected by changes to the physical aspects of the storage. ** For example, a changeover to a new disk. * The database administrator should be able to change the conceptual or global structure of the database without affecting the users.

** This should be possible while still maintaining the desired individual users' views. with kind regards M I K
