Oracle sql & plsql syllabus for payilagam Training institute chennai


Published on

We are a team of young blood. Some of our Payilagam team mates are Childhood friends, few college mates and few other as Colleagues in Professional life and ended as friends. One common thing about the Payilagam team is we have around Five Years of experience in the Software field.

When we came out of our college campus the entire world was new to us. Though we were alumni of various leading government and private engineering colleges, we experienced difficult situations and the road to reach this position had lot of hurdles.

Each of us realized that there is a huge gap between the 10+2+4 education system and the Jobs field what we want to be in. During our initial days of job hunt, we found many software training centers with fake promises of placement and career.

Some of our friends believed those fake promises, joined there with dreams and hopes but all went in vain. None of the claims of these institutes were true, are true and neither will be. These so called “Best Software Training Institutes” captivate the students not for the welfare of the students but for their own profit margins. These taught us strong lesson not to believe these software training institutes in Chennai. All these experience fed us thought for starting a software training institute in Chennai and in turn saw the seed ‘Payilagam’. We don’t endorse ‘Payilagam’ as the best, We don’t endorse ‘Payilagam’ as No 1 institute in Chennai, But we endorse ‘Payilagam’ with its moral.

We started Payilagam Software Training Institute with the moral vision to nurture professionals of high academic caliber and perfect character, nurture with a strong motivation and commitment to serve humanity. We aim at training our trainees to become not only skilled professionals but also excellent human beings to influence the quality of life of people around.

There were no one to guide us when we were about to start our career, But Payilagam is there for you.
