Microsoft Access ODBC

When using the client application by means of ODBC call to a specific data source, and through him – to the database, which he represents. When you install the ODBC is set of general and ODBC subsystem defined by a pair of "driver – the database", which is raised by the names used when connecting to the database. The corresponding pairs are called DSN – data source names. Create a data source is performed using ODBC Data Center Sours Administrator, called from the Control Panel window. The structure parameters of the source data includes: name and description of the source data server, to which they connect, the authentication method – the name of the database. There are three main types of data sources: user, file and system.

User data sources access to the data sources listed on the tab User DSN (data source user) windows ODBC Data Sours Administrator (Administrative data sources, ODBC), is only an account of the user who created them. Setting up custom data sources is similar to the setting of system data sources. If the error message says that there is no data source, you must first check to see if this user DSN. If so, then you must convert it to a file or system data source. File File data sources are data sources, similar to system resources, but unlike them, are stored in files, which facilitates the exchange of files between different computers DSN. If you want to use a data source for remote computer, the first thing to do for this – to make sure that this computer has the appropriate driver. For example, you can not use file data source for Access, if you have there is no ODBC driver for Microsoft Access. System data sources the System data source is available to any user of this computer. This, of course, does not mean that all egopolzovateli have access to the database, which refers to the data source. It just means that any scripts running on your computer, on which there is a source of data, can "see" the data source and use it to connect to the database data.

Preparatory Open

Today, before the swing of daily life is very common that young people abandon their studies without completing a career. Several factors influence this, however is one of those who have more weight, economic situation of families, where children face a reality that surpasses them, have to join the labour market. Unfortunately this serious situation is much more common than we would like. Fortunately this situation there are several opportunities to move forward and complete the unfinished studies or that did not have the opportunity to pursue. One of them is the school for adults, through the INEA; the second is the open option.

One of the levels with more registered is the school open, due to different situations among which we can mention the great demand for people who although they are already immersed in the labour sector have the aspiration and objective, despite his age in many cases, consider a career. Another case of people enrolled in the open prepa occurs among young people rejected from the leading universities in the country in their upper secondary level; in this situation young people who perform their entrance exam more than once without success, decide to enroll in this option with a view to recover lost time and to enter any University. In recent years the option of studying the open high school has been gradually displaced by another option of completing secondary education through a unique examination of CENEVAL, which as its name implies, is a global test of General knowledge that anyone with that degree must have; This option is much more comfortable, accessible, rapid and economical that the open system because requirements are minimal the most important is having 21 years of age at the date of the exam – and the benefits are basically the same. Then, either by policy official – before the international community is important to raise the level of education of the population of a given country already by business the most of the schools where there are courses for the open preparatory exams or the single review are private there is a wide range of possibilities for persons who have not been able to conclude with this level do so and even have access to a Bachelor’s degree.
