Why Manta? Why Manta? Because one size does not fit all.
Manta's customers range from individuals who need training on a single topic to Fortune 500 companies with IT staffs numbering in the hundreds. Manta's flexible licensing plans let everyone get the training they need at the best possible price.
A single-user, one-year license for any Manta course is only $120. Because the license is based on concurrent users, the only limit to the number of students that you can send through a course is your own scheduling ability. If time is a constraint, you can upgrade to a 5-user license for 1½ time the single-user price. Discounts are built in for multiple-course packages and multi-year licenses. How cheap does it get? We can train your entire staff for $750 per person, based on ten people sharing a single-user license over a year. Why pay more to train fewer people?
Check us out. This site includes our complete catalog, as well as a sample session from each of our 121 courses and exams. You'll like what you see.
President's LetterFor many people, the new year is a traditional time for reflection about past accomplishments and plans for the future. The IT industry shares this tradition. In recent weeks, both software vendors and the trade press have been overflowing my in-box with survey results and interviews that purport tell us what you and other IBM i shops will be doing in 2016. In a single word, the answer is "modernization."
"Modernization" is a word that has been bandied about at least as long as Manta has been in business. In 1995, it meant moving to ILE RPG. (Yes, it has been that long!) Ever since the millennium crisis passed, many people have used "modernization" to mean replacing the green-screen interface with a graphical user interface. Early adapters developed client/server solutions, which are now being replaced with web-based solutions. The great success of vendors in this marketplace suggests that a large number of IBM i shops have modernized their applications to at least this level. After all, it was that "ugly green screen" that most users and bosses complained about the most.
What's next? Vendors (particular IBM) are pushing new words at us, including "mobile," "cloud," and "analytics." Before jumping to these new technologies, smart shops are realizing that doing so would skip some steps. Modernizing your inventory of existing programs is much more than replacing the green screens with web-based interfaces. Two other steps are equally important.
The first step is to take a data-centric view of your applications. Stop using obsolete — and limited — DDS statements to define your data, and embrace SQL. Also use SQL statements within your programs to retrieve the data. Given IBM's huge investment in SQL performance optimization, SQL is much faster that traditional RPG statements to perform tasks like retrieving all records that meet specified conditions. You should also use trigger programs and referential integrity where possible to move business rules from within your applications to the database.
The second step is to finally fulfill the promise of 1995. Back then, many shops simply converted bad RPG III code to bad RPG IV code. It's time to take ILE seriously. Break those huge, monolithic programs into reusable procedures stored in service programs. If you have been waiting for a sign from the heavens (or Big Blue) to begin, the time is now! New free-form statements in RPG make the conversion to modern code easier than ever.
I'd be remiss if I didn't use this opportunity to act like the survey publishers and plug my own products. In case you were wondering, Manta does have courses on web development, SQL programming, free-form RPG, and ILE. If you have any questions, please call me at (800) 406-2682 x101 or e-mail me using our sales question form.
