In the term of the last months the main SQL Server got the whole set of brand new capabilities. According to the word of experts this doesn’t concern just the business intelligence inself.

One of the main features appeared to be the AlwaysOn, which now provides more significant capabilities within the infrastructure of the server. Such aspects as programmability, manageability, security and scalability are improved. The new components available in the new edition are made for analysis, integration and faster responding.

The query response within the In-Memory Column Store is also supported with the AlwaysOn system. According to the specialists’ point of view the new SQL is about 100 times faster than the previous one.

Starting the article, I decided to assume most people are already common with the database development and the details of its organization. Still I realized in the process that sometimes people dealing with the data protection aren’t really well informed about a lot of needful things. As we speak about databases, not all the developers actually know the aspects of the database security, as well as some issues that are security related can easily pass them. Moreover some databases are literally full of rather sensitive information.

So why would the companies through away awesome sums of money to keep their desktops and perimeters secure? Here are the main reasons to do so:

1. “I don’t see so I don’t care”. Usually the databases won’t get our attention unless they get slow or break down.

2. “Cat in a box”. Most compliance officers have no idea, what does actually happen inside the database aside from getting the needed information out of it.

3. “Welcome if you get access”. The feature of DBA is that they stay secure as long as you have the access, they will just go on tuning the performance of the database.

Every manager of the local database is usually in charge for a series of actions like integrity, performance and security of the given database management system. Also the database managers tend to plan and develop the database they’re working with as well as to deal with the incoming troubles of all kind. The specific details of manager work vary according to the databases and the inner nature of the organization that hired the specialist. The level of responsibility and the measures of control are also different. The manager may work with the entire database in all its aspects or be limited just to the database development in specified fields.

Many people tend to use MySQL every day, thus they need the system to work effectively. Here we offer the basic survey over the various types of this program depending on the company that released it. The healthiest MySQL is believed to be in the hands of Oracle. Still this type od the program is not the open source, still the open source programs seem to be the most wanted and valuable. However Oracle never tried to deal with the open source, so the company most likely holds to its natural course.

So who can perform the really best of the best software of this kind?

We assume it might be any firm that has the possibility to do MySQL development. The hosting based on shared infrastructures is popular today, still the developers do not think about it too often. The users tend to choose the database that is really comfortable to use. With it we can define two mostly common features:
- MariaDB, that obtains most features of the MySQL;
- PostgreSQL, that is also a nice alternative.

It’s not easy to protect data nowadays; still you will be much more protected if you cover the most visible vulnerabilities. This way your data will be secure.

The main thing is that most of the databases are not protected enough from the very beginning and it’s your trouble to protect them well enough. The administrator shall review the base regularly and close the unneeded packages so they will not appear the hole to dig into the database. The most important is however the regular patch.

Here are the most valuable ten features you shall keep in mind.
1. The password. It shall be complicated enough for the intruders not to break it in a second, leaving your database revealed.
2. SQL. The SQL injection is one of the most popular ways to get to your data and spoil it. Web database developers shall teach the system to avoid accepting all the data coming from the users.

Sometimes the application just refuses to perform the correct way. Usually we expect from the page in the internet to work fast and be as effective as possible. With a good connection it shall take no more then 30 seconds for the well-programmed web application.

Still some databases do not obtain enough performance issues and work rather slow for that reason. It’s usually easy to change the design of the application; still the database has usually a lot of applications downloaded. So if you opt to change its design, it might have drastic consequences.
Here are the main features you shall not forget if you really want to create a good database.
1) Variables that are bind. The query of the database shall be properly identified and optimized for the effective system work as database application.
2) Badly formed query. This might be the reason of significant problems in the SQL. Choose the adequate corresponding construct.

The way from the needs of the local user to the effective solution in the form of the software is rather complicated. If we’re talking about the proper database programming, we shall perform the set of actions for creating the needed software and for it to perform the needed actions.

1) Analysis of the requirements.
Before creating the database you shall understand completely what you are expecting from it so it will answer your needs completely.

2) The design of the database.
Choose the most suitable database model, so the final result will be just what you expected.

3) Selection and Evaluation.
After creating the basis of the database development, you ought to evaluate it and choose the appropriate system of the management.

Martin Fowler, the well known enterprise applications consultant, revealed some information about the database development. He tried to figure out of how they are related to the applications, and found it suitable to divide all the databases in two big groups. The first one appeared to be Application Database, while the other one was the Integration Database. The general difference between them was in the possibility to control the database and encapsulate it by using single database application only.

He found that not all people actually understand when and where the different styles of databases are being used. When being asked about the type of the current database integration, they usually get confused. However both forms of database applications carry their special features and shall be managed in a totally different way. Most people see the databases in the management communities as corresponding to the integration database type. This conclusion has been made for years and is rather typical nowadays. Still there’s a question some users still can’t give the right answer for. If we have a close look at the Integration Databases, they appear to have the large surface area for the interface as well as the tight connection in-between the interface and the implementation. The links within this database are stiff and hard to change if needed. They are brittle enough to be a problem for the user in case the fix shall be performed.
