what is meant by database security?

There is two basic concepts with database security:\n\n1. Access Control \n\nOnly let those who you want to have access and permissions to do what you want to allow them to do.\n\n2. Data Security\n\nIf data is obtained from the database, to what extent is the data protected.  Encryption is the concept here.

Depends on what your currently doing right now. Of course authentication and authorization are huge topics in the security feild.  But for starters, don't store any plain text data.  Use strong encryption (3DES, Blowfish, AES,MD5, etc...) on any personally stored information.  \n\nTake a trip over to the open source web application securty project and have a look at the top ten list of common web application vulnerabilities. This should be a good starting point for you.

you should be able to limit access via the database interface, if it's something that you've built, then make accounts and force logins, or if it's something like phpmyadmin, then go to the mysql database and edit the users table as you need it, it  has an easy to understand y/n priv system

Secure connection. Normally appears when you are prompted for secure info like passwords, account numbers, ssno etc. Info that you wouldnt want to fall into the wrong hands.

In case you wanted to run more than one database for your site.\n\nEg. a database of customers/clients, and a database of your products/services, and still another for your staff to log-in, and yet another for your suppliers...

Advantages of a Database\n·        Reduction in data redundancy \n·        Maintenance of data integrity and quality \n·        Avoidance of inconsistency  \n·        Reduced cost of software development  \n·        Security restrictions  \n\n\nThe biggest advantage is that if a standard way to organize and store data that  allows you to decouple the representation of the data from the software that uses it.\n\nThis allows you to move or reorganize data without have to find every program that uses the data and change them to match the change in the data. \n\n\naccess speed and increase in space to represent the data are the big disadvantages.

Use mySQL and secure it. Plus, once it is set up you can manipulate it so much easier.

data integrity  \nRefers to the validity of data. Data integrity can be compromised in a number of ways: \nHuman errors when data is entered \nErrors that occur when data is transmitted from one computer to another \nSoftware bugs or viruses \nHardware malfunctions, such as disk crashes \nNatural disasters, such as fires and floods \n\nThere are many ways to minimize these threats to data integrity. These include: \n\nBacking up data regularly \nControlling access to data via security mechanisms \nDesigning user interfaces that prevent the input of invalid data \nUsing error detection and correction software when transmitting data  \n--x--\ndata security     \n In the computer industry, refers to techniques for ensuring that data stored in a computer cannot be read or compromised by any individuals without authorization. Most security measures involve data encryption and passwords. Data encryption is the translation of data into a form that is unintelligible without a deciphering mechanism. A password is a secret word or phrase that gives a user access to a particular program or system.

Standard SQL tends to fall under DB Programming.  When you get into store procedures you are starting to get into DBA work.  That also include database integrity, index integrity, index definitions and rebuild of the index.  DBA's are the ones who actually define the table structure and the internals of the database.\n\nDB Programming is involved with actually adding, modifying and querying the data that is stored in the database.

Your question seems to have gotten cut off.  However, are you referring to referential integrity such as primary and foreign keys?

I think it has to do with the development of online payment, security (all kinds - this area will never cease to develop), storage management (databases will be the heart and soul of any business very shortly... some might say, that time is now, but technology is really pushing the barriers on this one. The use of databases will change and develop quite a lot in the near future - by means the information will be filtered and who knows what).

Validation of data is must to avoid errors in application and to avoid duplicate data in your database.\n\nthere are lot of validation type, simple one is using primary key validation. other validations are, foreign key, default value and other types.
