Though the current databases need new solutions, the well-known RDBMS is still active and working. Still there are places and cases where it shall not be used for your own sake. Even the people who are really fond of Oracle, RAC or any other system of this kind shall reconsider their urge to use their favorite ways in the following cases.
Do not use Oracle Text. It’s not usually used even by the Oracle lovers, since this database extension doesn’t develop actively. The other ways database developers tend to use in Oracle are either too primitive or too complicated; both options offer the bad kind of results.
However you can easily use Autonomy, Apache Solr or Hibernate Search for your task. This way you will get fast and handy results.
If you work with ATG Commerce, try to avoid this action by all means. The reason for this option to be turned off most of the time is the great scalability – database developer just does not need that many recommendations for his work. This feature is not usually needed at all, since the tasks people solve are really various, so you just do not need recommendations based on someone else’s actions.
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.
It doesn’t look like the answer will be an easy one. Most shops will be completely satisfied with any of the versions, even if they end up with the worst possible selection. It’s not easy to choose the best as all the good database developers will try to balance perfectly the support availability, the project strength and of course the code and documentation quality offered in the particular database.
The most noticeable divergence we can see in the extras. Most of them tend to store a lot of keys with the encrypted values; still the most important is how they spread data across the accessible servers and how effective they can run the changes across all of them. The hosting question is no less important. The cloud service will be the most suitable if you’re seduced by the clear maintenance.
The database choice was particularly easy no more then three years ago. The people with a significant budget opted for Oracle. The fans of Microsoft run the installation of the SQL Server. The specialists with zero budget opted for MySQL. It was easy to choose between these three options.
Now the times have changed. The new projects appear faster then the users can actually comprehend what they’re dealing with. Most of the projects just do not follow the basic rules of safety thus offer practically no protection the database developers expect for. A lot of them call their IT inventions MySQL and even NoSQL, perhaps they consider it to be Not Only SQL.
Most of these programmers finally manage to offer something that works considerably fast and is rather scalable. However this is all good about it, as most of the traditional crutches are abandoned. The professionals with their experience of the old school are waving their heads in shock, as the new applications will surely stumble and even snap over the troubles the more formal people have fixed long ago. Still the whippersnappers do not care about it, as their goal differs much from what the veterans have in mind.
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.
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.
In the modern variety of the features offered by the databases the typical user may just get lost. As an example the popular Oracle has plenty of specialties and options, some of those are frequently used while the others might stay neglected. The feature that most users need in their daily business is the well-known ACID offering the set of compliant transactions. The best way is to choose the major functions like stored views, procedures or snapshots as well as table datatypes or transactions etc. As the Oracle, MySQL and Postgresql are the most frequently used programs, let’s discover the set of mostly used features in each of them.
It’s not a secret that every one of these databases has its own unique advantages and weak points. Learning the database programming, it’s important to keep in mind these features for the correct and effective work. Every database, even if we’re talking about the most reliable one, has some hidden troubles that not necessary fall into your eye from the first moment. Do not forget about the recent updates and patches the database obtains. Usually the open-source needs more attention then any code itself, so you will have to be much more patient here. The pressure of any community is much stronger then it usually is in the open-source area. Talking about the vendor can or some commercial space, the repair here is harder and much more expensive then the cost you will pay for the in-time fix.
