For one thing, it contains the word "c**t".

The relational model isolates data by object and identified references (foreign keys) to those objects. This is usually captured in a table with multiple attributes (columns). The foreign key is a data value that refers to another data object (another table) which has its primary key as the other object's foreign key. The virtue in this is summarized in Dr. Dodds data normalization theorems.

Hierarchical modeling takes the normal model and summarizes it in a tree. In effect we take a cartesian join. This is usually done in datawarehousing. This is important because we begin to look at layers of the object model rather than views of the data store. Aspect analyiss of the data in hierarchical models depends on the tree structure and is focused on each data object. The tree model contains objects that are replicated.

Each have completely different benefits when coming to the mechanics of persistence and indexing. The true model is to identify what I've called the DATA TRIANGULATION MODEL where data consumption (often GUI or reports or reference calls), persistence, and prominence are characterized. Choice of mechanics between which is most useful comes from these three elements. We realize this model is incomplete as there is the OOD and list theorems that can corrupt the DATA TRIANGULATION MODEL.

We return to mechanics at this point because that is what limits us. IOPS, persistence, availability, durability, and supercalifragilisticexpialidociousability. -cja stopher2@gmail.com

How it is possible that one is so free for you that he/she start designing on behalf of you !

I know it is very important for you , but this world is selfish , they can waste their time with their girl friend but dont have any time to make diagram for you !

Filtering is the act of removing unwanted values from a result set. For example, if you have a database with 10,000,000 phone numbers, you might want only the phone numbers in the 215 area code, or only the phone numbers of clients that have purchased at least $500 in the past 12 months.

This question needs some context in order to give a reasonable answer. Please provide a bit more info

PHP and MySQL are two of the important technologies in today's technical world. There are many companies that offer web hosting for PHP and MySQL. Some of these companies are WordPress, Zymic, b2evolution, 000webhost, freehostia, prchecker, siteground etc. Some of these companies offer free web hosting services.

For example if we have database named "users", and we need user information from table "user_info", which has next parameters: 'userId', 'userName','Name','Age'. $sel = mysql_query("SELECT * FROM users.user_info WHERE userId='$methodId'"); $ar = mysql_fetch_array($sel); echo "

User Id is:".$ar['userId'].", UserName: ".$ar['userName'].", Name: ".$ar['Name'].", Age: ".$ar['Age']."

Google don't use Oracle or MySQL, they use their own database software known as Bigtable.

Entity can be an account, activity, or contact about which data can be stored.

One of the tenets of relational database design is "normalization". Normalization is the process of reducing a complex data structure into its simplest, most stable structure. In general, the process entails the removal of redundant attributes, keys, and relationships from a conceptual data model. In database design one has to make decisions about the trade offs offered by normalization. A completely normalized database can offer a great deal less redundancy and offer a infinite complexity and relational flexibility to the user/designer. On the other hand, this can get out of hand. The downside is that queries get overly complex and it can slow the database to a crawl as more and more data is accumulated. A simple example would be that of a database that represents an address book. The simplest design would be a flat database or a single table with columns like name, address, home phone, work phone. This would be a very fast, easily queried database but somewhat limited. What if you have someone who has more than two phone numbers? what if you want to put in their work address or the address of their vacation home. The fully normalized version of this database would have a core table for contacts that would link to a table of addresses, a table of phone numbers, a table of zip codes. There would also be tables called look up or type or category tables that would list the possible categories for phone numbers such as work, home, fax, cell etc.. as well as a table for address categories, work, home, vacation house etc.. you could also add a category table for the relationships between you and the contact and one for the relationships between contacts e.g, 'my friend', 'my boss', 'his sister', 'her uncle'. The Pitfall here is this database would quickly get too complicated for unsophisticated users to query and understand and it would get slow as more and more data was accumulated.

Xequence-- The pitfalls in relational database design is that you must learn the system. This process of 'learning the system' will take some time. Another pitfall is that everything must have referential integrity. Not an easy task to think about. The last pitfall in a relational database design is the length of time it requires to build stored procedures and triggers. These values cannot insert null values into a [does not allow null] field that is relational to a foreign key table with more cannot insert nulls that have constraints if the values goes below 0 to email a man in Nantucket that his gridview errored out on line index 4 with his foreign key constraint. *breathe* It gets better..

A sample objective statement for a receptionist might include 'a receptionist position with this company to utilize customer care that is exceptional.' You might also include strong clerical skills with an expertise in front desk operations and management.

You have to be careful about what you store. There is legislation in many countries covering data protection. That affects databases. Your data needs to be accurate and up to date. You need to be storing it for genuine purposes that users are aware of. You need to be able to prove why you need it. You may need to get rid of it after a time period or once it has served its purpose. You cannot pass it on to anyone else without the permission of the person that the data is about. All of these things are ethical issues in relation to databases.

SQL is a universal query language used to access relational data. MySQL is a database storage engine which utilizes the SQL query language as the means to interface with the data stored.

That depends on your project. If your project has simple database, tables and queries then mysql would be the ideal choice. If there is complexity involved then use of mysqli or PDO is better.

You can use criteria for fields to restrict what they can show. The criteria could be something like to only show records that have a field with values that are over a certain amount or to only show records that contain specific data. So you could have a list of staff, but only want to show those working in a particular department, or you might have a list of exam results but only want to show people who achieved a score that is higher than a certain amount. You do this by applying criteria to the appropriate field.

MySQL and Apache are two totally different things, you only see them together a lot because a lot of Web apps use MySQL to store info in the database. So yes, you can use mySQL without Apache.

yes.

You can use a template and customize it to fit your personal hotel management system, or you can do one from scratch. There is no wrong or right answer.

updates- a change to the name of a sale rep requires not only change to the table, but several making the update process cumbersome.

inconsistent data- there is nothing about the disgint that would prohibit a sale rep from having two different names in the database.

addition- in order to add sales rep 87 (mary daniels) to the database, she must already present at least one customer. if she has not yet assigned any customers, you must add her record and create a fictitous customer for her to represent.

deletions- if you deleted all the customers of sales rep 35 from the database, you would lose all information concerning sales rep 35.

what is the difference between sqlplus and sqlsever

SQL*PLUS is oracle command line utility that allows access to Oracle databases

sqlserver is a Microsoft RDBMS (database management system), vaguely based on a Sybase RDBMS

if you are looking for SQL*PLUS like interface to SQL Server, the one one is SQLS*PLUS from www.memfix.com

MySql is a database application of programming for developers, PHP is the web server scripting language for developers, application of programming.

Whereas Magento is a eCommerce software platform for customers , which is built upon PHP and Mysql by developers.
