Review of Interactive Online SQL Training for Beginners
The tutorial starts by giving an in-depth analysis and explanation of what is SQL and how it works to get information from databases. The tutorial welcomes readers and prepares them for the learning task ahead of them. Interactive Online SQL Training for Beginners uses simple, straightforward language to train users on how to manage their databases as well as retrieve data from the databases effectively without limiting the access of data from the relational database management system (RDBMS). When using the tutorial, the following are the lessons that users learn.
Table Basics
The tutorial starts by explaining the main layout of the relational database system to create a picture of what the user will get in subsequent lessons. Other than just defining the table and its structure, the tutorial gives an example of a database table with some information.
Selecting data
After introducing what a database looks like, the Interactive Online SQL Training for Beginners starts showing users the approach and method they needed to use to select data from a database. When selecting data, some command keys needed to be learned and the tutorial explained them adequately.
At the end of this section, the tutorial gave the user a chance to test what he has already learned in parts one and two (QuinStreet Inc. 2011).
Creating Tables
The next lesson that users get from the tutorial is how they can create tables and make some deletions, and insertion to manipulate the information they want or make the information in such a format as they would understand better.
Inserting into a Table
The next section of the Interactive Online SQL Training for Beginners covers how to insert some information and data into database tables. After explaining the process and the command keys to use, the tutorial offers an example which is a practical situation that users can attempt. Such an approach assists in understanding the operation of the database and how one can manage and control users. At the end of the section, the tutorial offers users a chance to try his expertise got that far (Isrd, 2007).
Updating records
Databases need to be regularly updated; the tutorial offers an explanation of how data and information stored in the database can be updated and new information and features added.
Deleting Records
Sometimes users or database managers may need to delete some records, data, and information from their databases; Interactive Online SQL Training for Beginners gives in-depth training on how someone can delete records effectively and retain the quality of the stored information. The section of deleting records has been strategically placed under updating records since some deletions may result from updating database tables.
Drop a Table
Other than deleting a certain record, there are times that database managers may need to delete an entire row or column, and in some cases an entire table. The tutorial offers the process that should be used and also gives an example of how one can delete such information. Every section in the tutorial is self-explanatory and follows the right structure to facilitate fast understanding and imagination.
After the in-depth analysis of how to manage databases, Interactive Online SQL Training for Beginners introduces SQLCourse2 to improve the skills and knowledge that the learner has attained from the tutorial. The tutorial offers to advise that continuation of the course is likely to improve users’ skills and make them better database managers (Informix Software, Inc, 2000).
How effective was the tutorial, who might find the tutorial useful, and any other aspect of the tutorial that you think a reader might find useful
After going through the tutorial, I have found it interesting informative, and comprehensive. The approach used by the writer is straightforward and builds on issues slowly but sue. Beginners need such tutorials as they can simply explain database management and capture the attention of users. To test understanding after every segment the tutorial is offering an example followed by a task that users can use to test their understanding of the matter taught in the previous lesson. The writers of the tutorial seem to be fully conversant with the area and are willing to share their skills and experience with users.
The command languages that are used in the tutorial are similar to the command language that users are likely to get in real situations case; this helps in creating the right picture for users right from the start.
When tutoring, the system assumes that the user is ignorant about database management thus it starts from the simplest elements of database management and retrieval of information then builds on the understanding to offer the training. For users who have used tutorials again, the system offers a good refresher to sharpen one’s skills and expertise.
