Okay, but what database tool should I use?Īfter knowing a little of the subject, we can return to our main goal: simply to get data stored in large databases (Oracle, SQL Server, etc.) for use in our work with simpler programs like Access or Excel.īy the title of the tutorial, you should already know that our choice is ‘Toad’.įor that choice, and our goal, we take into account some features, and one of them is whether the tool is free or paid. But this also is not our goal, and if you want more details on these and other tools, we suggest reading the comparison of database on the website of Wikipedia. We could continue with the list, or start to detail the characteristics of each of these existing tools, to which database apply, whether they are free or paid, etc. The list of options is pretty big, and we can list some of the key: This really is a controversial question, because we have ‘diehard’ defenders of several good options. And then, what are the best alternatives to database tools? That is one of our goals today: get the best solution for such access. We’re just focused on bringing the data that we need a database of more ‘complex’ to one that we are more used to work.Īt this point, we now have another problem: what is the best tool to accomplish the access to this database? Note: it is not the intention here to discuss the advantages and disadvantages of a most popular database like Access, or Excel spreadsheets (which in a way can also be considered/used as a ‘database’). From that point, we can work on the data as we want. And then work with it using programs which we’re most familiar with, such as Microsoft Access or Excel. In other words we can ‘bring’ the data from large databases for a more ‘friendly’ format, or a more controlled environment for not so advanced users.
So, you don’t run the risk of making any ‘crap’, and can do your job. However, exposing the need, you should get at least a ‘read-only’ access to data. Note: it is common for the DBA’s to offer a certain ‘resistance’ to allow access to these stored data - which is understandable - they want you to access only through the interfaces that they suggest/build. The access to these raw data is also useful in cases where the information serves as input for other analyses and reports, and getting the same manually would be an unnecessary limit. for a deeper analysis where we need more fields then the fields shown in the standard tables/reports). This can occur for example when the ‘Client’ applications does not have all the necessary data for the analysis (e.g. But there are cases in which ‘direct’ access to the original data stored are much more desirable or even necessary. Note: This is not a tutorial geared towards DBA’s, although if you are one, feel free to join us.Īll databases can export their data and reports through specific applications - usually a Web interface or a specific/proprietary application.

In addition, we will see how to configure the Oracle Instant Client, avoiding the local ‘installation’ of an Oracle database. As an example, we’ll show you how to access data from an ‘Oracle’ database.
Learn about a free tool (Toad Freeware) that allows us to work with large databases. And it is from there that enters our tutorial today. And this kind of professional, known as DBA or ‘DataBase Administrator’ is responsible, as its name suggests, for the entire administration of the database.Īmong other things, the DBA can provide access (connection data, user, and password) to the database under its administration. Well, let’s keep it simple: this is much more complex, and is handled by specialized professionals. The databases, among other features, can be classified as relational and Non-relational … As an example of good databases we can quote ‘Oracle’, ‘SQL Server’, ‘IBM DB2’, ‘MySQL’, ‘SYBASE’, among others. It is natural that in a niche so defined and with so much expectation of growth there’s a lot of competition, and consequently several (good) options. In the Telecom and IT area for example, numerous elements, alarms, meters and gauges, complaints and service calls, customer data and various other variables need to be stored properly so they can later be processed to extract results as analyses and reports. And in any area where there’s this need for data usage, there will also be a form of storage and control thereof, such as large databases. The trend is that this growth will increase more and more. There’s no doubt the use of data nowadays is much bigger than just a little while ago.
