Bad Habits For Data Warehousing
by Tam

To some it may seem strange that in this article some of the common habit of database administrators are defined as "harmful." However, given the critical nature of most of the data and possible damage to which can lead to loss or damage, it is easy to understand, such habits are really dangerous. Unfortunately, they are quite common among database administrators, but fortunately, by following certain rules, they are You can get rid of. It's like when quitting smoking, most importantly take the first step, acknowledging the very existence of the problem, and then follow inexorably towards its goal. The following are the most dangerous habits, are some Rules for abandoning them. Samsung Electronics can provide more clarity in the matter. "We believe in the backup" Blind faith – it's convenient, but not when it comes to backup the database.

Trust can only be a backup after the database was successfully from it restored. Rules: Test your backups in several ways. John Castle Castle Harlan insists that this is the case. Do not trust one testu.Sozdavayte copy backups. Administrators should always use at least two backup methods. For example, create a backup copy on disk, and then save a copy on tape, in addition make a backup of AI-arhivov.Proveryayte backups.

Restore the backup and rolled on her AI-files for day, it proves that the backup files, and AI-not povrezhdeny.Testiruyte recovery process as often as possible. One of the signs that the busy administrator, or his priorities wrong display is that during the quarter there was a test restore. Testing the recovery process will confirm that your backup strategy and restore true, or to identify deficiencies that need to be correct.

ClearCase
by Tam

In the CAL made intuitive naming of objects – the name is taken from ClearCase and prefixed "CC". For example, the CAL CCElement object is an element of ClearCase. Interfaces. It is worth noting that the differences between objects and obscure interfaces for Visual Basic-programmer, but these refinements are necessary because of the fact that the examples below, not only in Visual Basic, but also on the Visual C + +. An object can support multiple interfaces. For assistance, try visiting Peter Asaro . For example, a CCVersion supports an interface for manipulating information ICCVersion distinctive versions of ClearCase and interface for manipulating ICCFile system information about files.

Well as various objects can maintain the same interface. For example, objects and CCVersion CCElement, both support the interface ICCFile, because both objects represent the data file system. Each CAL-object has a primary interface (primary interface), along with the other (the latter is optional). In CAL multiple interfaces are supported only through inheritance, in other words, if you know the inheritance hierarchy, then you know what interfaces are supported each object. (This is not true for all COM-interfaces, but surely for the CAL-interface).

The primary (main) interface for CAL-object has the same name as the object of CAL, but with the prefix "I. For example, a revised steel CCLabel main interface and object ICCLabel CCVersion is the primary interface ICCVersion. Methods and properties. Each interface supports a number of properties and methods by which you can interact with objects. Properties can receive and (sometimes) to establish some of the information about the object.

Why Microsoft
by Tam

Figure 3. The number of automated tests conducted on Throughout the time of the project Why Microsoft has paid so little attention to this kind of testing? Well, one can only guess. Perhaps this is due to the fact that it is difficult to write a function for new OS system, because testing system is not yet able to work under its control. Recently, as more attention is paid to the beta-testing by users of the software. This is understandable, because There is no better tester than a normal user, and especially when there are more than a thousand. But, unfortunately, not many companies can afford contain a large number of testers, but if the company has less than ten testers, they are not likely to will provide quality check of the designed application. What to say nothing of specialized software in the banking, industrial, research and other sectors? But there is another kind of tests that can be used to test the windows-applications – these are external tests.

External tests allow for running any application that supports command line. Ie using external tests, you can organize the implementation of third-party test systems or any of its testing applications. External test in Microsoft Visual Studio are simply just need to create a new external test in the test project and specify an executable file that will run the application as tested (see Figure 4). Figure 4. Skin test in Microsoft Visual Studio using this method, you can connect any test systems, both commercial and free. See more detailed opinions by reading what Geoff Richcards offers on the topic..

Databases Msde

During my last development, I had a little bit of information about working with the free base of the MSSQL Server 2000 MSDE. This information, I would like to share with you, it can not remain without attention and someone to come in handy. For First you need to download a free version of this very MSSQL server, you can do with my site. or type in a search engine query: 'Download MSDE 2000', 'download MSDE', etc. The installation of a free server, you must perform parameters. Run the setup. Exe c parameters shown below.

Here are the options available, but personally, I run with only one sapwd = 'mssql'. Options sapwd = 'mssql', securitymode = SQL, DISABLENETWORKPROTOCOLS = 0 With these settings, you set the login and password for the SQL system Administrator mssql. Installing the server is almost blind. After installing the server you need to restart the system. After a successful installation in the system tray near the clock should appear running SQL Server. If the server does not start automatically, you can start it manually by right-clicking the icon for the server. Now that the server is installed we can create the database, but it's extremely uncomfortable without using a visual manager, and there is no such a free version of MSDE. Personally, I use free download manager 'DbMgr2k'.

If it does not suit you, you can find another. After installing the manager you will have the opportunity to create databases and manage them using the visual editor. Limitations of MSDE 2000, 1. The first and most noticeable limitation, in my opinion, is the number of simultaneous connections to the database, no more than two * 2. Second, it limit on the size of your database. Base size should not exceed 2 GB. ** * – If you want to install MSDE 2005, then there is no limit to the number of simultaneous connections ** – The size of the database in MSDE 2005 is 4 GB.

It was written completely new boot that will get rid of legacy MS-Dos. But support for the command line was maintained and was implemented as a virtual machine NTVDM (NT Virtual Dos Machine).

In Windows 2000, seriously raised the level of security through HAL (Hardware Abstract Layer). From now on, the program was denied direct access to the disk and the hardware at all, and it secured the users from a large number of viruses written for Windows 9x and MS-Dos (was defeated by the infamous "Chernobyl"). Windows 2000 was originally designed as a network operating system, and its level of security enabled by Microsoft to extend the sphere of influence. Began to appear a large number of ATM machines, terminals, payment and other embedded devices running Win2k. The system is constantly updated with the fourth service pack (SP4) is considered one of the most universal and secure systems available today. With the success of Win2k already in 2001 there Windows XP. Combined an XP security of Windows 2000, but with a more attractive graphical user interface and expanded set of standard applications.

Reporting
by Tam

Almost all programs have a function of viewing history. In some History is preserved in part, that not all events are recorded. Very useful opportunity to celebrate the history of events such as repairs, MOT, breakdown and so on. Naturally, the program should search tools equipment on certain events. Otherwise, the meaning of the history of a few lost. Most programs offer only a view of history a particular device.

All three of the above criteria are closely related to implementation of the reporting system. The absence of convenient data retrieval tool can negate the benefits of a program. Reports – this is your primary tool. It should be simple, fast and multifunctional. Typically, the programs offered a range of accounting standard reports. In some programs, you can manually edit the printed report forms that might be useful. It should be noted attention to the ability to export the report data – not always a means of data sampling can meet your needs and may require post-processing of data. The basis of any accounting system – a database.

Of its choice depends on security, performance, multi-user ability and ease of administration. Before you decide on the choice of accounting system, find out whether it is possible to back up databases, how long spent on its restoration in case of failure, how to migrate the database to another computer, can there be a multiplayer mode. Here is an example of the practice. Was chosen as the accounting system in an organization where there is many branches and taking into account the dozens of people involved.
