My OJT Experience: The Work Environment and Lessons I've Learned

Image
Hello! Welcome to my blog. I am Svet Leighann T. Señeres, a student from BSIT 2B. In this blog, I will talk about how my experience was during my OJT. When I first found out that we were required to undergo OJT, I felt excited to experience it. However, it was unfortunate that we could not experience to work onsite due to the pandemic. To be honest, I thought that it would be easier as everything had to be done in a virtual setting, but I was wrong. It was difficult, especially applying for a company and looking for an offer that was aligned to my program. It took me a few months before I was able to find a company that was willing to hire interns and at some point I thought it was almost impossible for me to finish my midyear. Thankfully, I finally got to start my OJT and render my hours. I had to manage my time in both my OJT and class and somehow make it work as I started mine during the start of classes. Although the tasks that were assigned to me were not that aligned to my progra...

            Hello! Welcome to my blog. I am Svet Leighann Señeres from BSIT 1B and today's topic is about SQL!                                                  WHAT IS SQL?            ___________________________________________________________________________________           SQL or Standard Query Language is a set based, declarative programming language. It is used to perform tasks on a database. The history of SQL traces back to 1970 when Edgar F. Codd, an IBM researcher defined the relational database model. IBM used his findings as a basis to develop the SQL language. It was originally called as SEQUEL or Structured English Query Language. But after a few revisions, IBM stuck with the name SQL.

MY CLASS EXPERIENCE

Image
  In our information management subject, I learned a lot about databases, different diagrams models and how to use Microsoft Access. However, I think I would have understood the topics better if it were in a traditional, face to face classroom setting because it is difficult for me to grasp information at a quick pace. It was quite challenging to learn in this type of class environment since this method of learning is still new to me but given the situation that we are in as of the moment, we are left with no choice but to study online instead for the safety of the students and the instructors. Dilemmas were faced during class as technical difficulties are unavoidable and it is understandable because everyone is still trying to get used to online classes. Just like everyone, I also experienced these as sometimes I had internet connectivity problems and it would be stressful on my part as it would hinder me from entering class and passing requirements on time. I look forward to atta...

It can store large objects such as images and documents. Other than that, Ac...

FUNCTIONS, ADVANTAGES, DISADVANTAGES OF DBMS

Image
  DATA DEFINITION In a DBMS, data is what's being dealt with and data definition is the ability to clearly define what is stored in the tables of a database. As an example, SQL is utilized in order to instruct how to store the data.    DATA MANIPULATION   This means that the existing data within a DBMS can be easily manipulated. Modification is easy as users can insert, delete and update their database. DATA SECURITY AND INTEGRITY Enhanced protection is ensured in a DBMS. It prevents any type of unauthorized access and data alteration. On the other hand, integrity is the validation and it helps maintain the overall accuracy of the system's structure. DATA RECOVERY AND CONCURRENCY   System failures can be unavoidable and DBMS has the ability to retrieve the lost data. Other than that, concurrency means that it can be accessed at the same time as multiple users can view it.  DATA DICTIONARY  A data dictionary primarily consists information regarding the ...
