Recently i have come across a new or not so new programming language IBM's Enterprise Generation Language EGL. Browsing through some of the articles and tutorials in the net, i came to know that it's a new 4GL which can generate java and cobol code. It's a programming language which let us writing full functions applications. As i said it's a new language it has its own syntax and learning curve. However IBM claims it's easy to learn compare to Java. When i look into the syntax of EGL, it has remind me COBOL which i have studied during my engineering. IBM RAD can be used to develop EGL application. EGL can be used to develop web application which will eventually be converted into java code. EGL contains programs and libraries to create your bussiness and data layer. It has page handlers and jsp's to create presentation layer.
EGL tries to bridge between procedural and Object oriented programmer. It claims that procdural programmers and 4GL developers can develope java web application in EGL with or little knowledge of Java.
However as a java/j2ee/php developer i have certain concerns whether to accept EGL or not.
I would appreciate if someone (EGL experts) to answer below questions. Also request all you readers to continue this discussion which might help someone to choose among EGL,php,java and so on and forth.
Question1: As EGL says a procedural programmer need not to know Object oriented programming. Do they really need not to learn OO ?
Question2: How can we trust EGL, when most of the 4GL are out of market and in the process of migrating to x,y,z technology?
Question3: EGL programmer's need not to know Java/j2ee... However there many best to be proven framework/design pattern in java/j2ee/php. How one will implement these patterns wihout knowing those?
Question4: How about maintainability, scalability, performance, extendibility, reliability and security compare to hand written program in java?
There are many more questions which EGL has to answer before it goes big.
I think we should not have any problem accepting a new language/technology which is better than current trend of technlogy. However it cannot claim global audience if it is just better than some of out of market trend technologies

EGL seems very similar to Cool:Gen (CA:Gen), the oldest of the CASE tools. Gen, as it is popularly called, has been around and a proven technology for ages.
In brief response to your questions: first, the EGL developer has no need for an object orientation; second, the trustworthiness is shown because the firm has a long history of protecting customers who used precedecessor language and, more important, because the extensibility of the new technology means that IBM has an easier time updating the language for new run times; third, the language is possible because of patterns and allows the developer to reach beyond the language, to the underlying runtime capabilities; and fourth... well, that's a big question you've asked, but in short, I think you'll be pleased at the level of performance and scalability being provided, and EGL offers JEE security and LDAP support.
Here's an introduction to EGL: http://www.mc-store.com/5087.html
For past couple of months I am observing and using EGl widely. Firstly trained by Jonathan Sayles (we call him Jon), EGL Application Developer/IBM and then worked as an architect of the EGL based project. I am started liking EGL. However I am still sticking on one point that is EGL programmer should know Java, Javascript, jsp, servlert..because there are good many features/requirement which can be implemented easily with Java/j2ee/javascript than making things difficult using EGL. One has to admit that EGL is coming up very good and fast. I/We call EGL as .NET of Java/j2ee.
It is hard to believe that anything [B][URL=http://www.mbtplus.com/]MBT[/URL][/B] so inherently ugly as the MBT shoe could ever catch on [U]mbt sneakers[/U] with either the younger generation or the fitness fanatics but it has. [B]footwear etc[/B] The shoes or I suppose they should be called trainers have thick curved soles and wide straps across the front. Currently [U][B]mbt sneakers[/U][/B] the are available in over 20 countries and have sold more than a million pairs a year. Considering that they have a price tag of around $200 it is even [B]MBT shoes[/B] more remarkable.
MBT shoes, which stand for Masai [B]mbt discount shoes[/B] Barefoot Technology were invented by Karl Muller a Swiss engineer. He [B]discount mbt shoes[/B] suffered back and knee problems but on a trip to Korea he noticed [U][B]MBT[/U][/B] that after walking barefoot through paddy fields the symptoms were relieved. With further [U]MBT shoes[/U] research he discovered that the Masai tribesmen from Kenya did not suffer back problems [B]discount mbt shoes[/B] and had perfect posture. Putting these two facts together he decided that [U]mbt shoes sale[/U] the answer was because they were walking on soft surfaces [U]MBT shoes[/U] which yielded as they trod on them. This [U]mbt sneakers[/U] was unlike in Europe and America where we tend to walk on firm surfaces such as sidewalks.
The first MBT was manufactured in 1996 and soon [U][B]mbt sneakers[/U][/B] became popular on continental Europe. Since then many celebrities have [B]MBT shoes[/B] been seen sporting MBTs. The concept basically is that the [U][B]shoe for worked[/U][/B] curved sole creates instability as you walk, which [U][B]mbt sandals[/U][/B] mimics the effect of walking barefoot. To counteract this the foot uses muscle to counter this [B][URL=http://www.mbtplus.com/]mbt shoes best prices[/URL][/B] and creates a natural body training effect.
These are pretty bold claims but there is no doubt that MBT shoes are [U]shoe for worked[/U] popular both as recreation and sportswear. A study [U]MBT[/U] by Sheffield Hallam University recently concluded that MBT shoes were better for the knees ankles [U]MBT shoes[/U] than normal shoes. The study also concluded that if [U][B]mbt shoes clearance[/U][/B] you walk correctly you would take shorter strides while walking in MBTs. Shorter [B]mbt shoes sale[/B] strides would mean more steps and more expending of energy and this [U][B]mbt discount shoes[/U][/B] would increase your calorie burn.
If you're interested in improving your health, it [B][URL=http://www.mbtplus.com/]mbt walking shoes[/URL][/B] can be beneficial to start from the ground up. Let's talk about your footwear. How does [B]mbt discount shoes[/B] yours rank? Some so-called fitness shoes merely look great, but don't really provide [B]mbt discount shoes[/B] any actual health benefits. Other shoes actually make a [U]mbt shoes clearance[/U] legitimate difference. If you want footwear that truly helps, MBT shoes are the first [U][B]footwear etc[/U][/B] step toward a healthier you.
What does MBT stand for? Good question. The [B]mbt shoes cheap[/B] answer: Masai Barefoot Technology. They're designed to [B]mbt shoes review[/B] simulate walking barefoot, which helped our ancestors to walk [U]MBT shoes[/U] healthier than we do. Modern humans cram their feet into all kinds [U][B]MBT shoes[/U][/B] of crazy, uncomfortable shoes, and we walk on [U][B]MBT[/U][/B] unnatural surfaces. MBT returns our feet to their natural, healthier [U]buy mbt shoes[/U] environment.
MBT shoes actually trigger and enforce the [B]mbt shoes cheap[/B] tiny muscles that cause our bodies to naturally absorb [U]mbt walking shoes[/U] shock. The patented construction of the MBT soles features a [U][B]mbt discount shoes[/U][/B] unique sensor that causes a simulation of being on uneven [U]mbt shoes review[/U] ground. It causes an instability that causes the body [B][URL=http://www.mbtplus.com/]discount mbt shoes[/URL][/B] to react with slight movements to compensate for the instability. Thus, a "rolling" process [B]mbt sandals[/B] begins. This active, natural balancing act causes our bodies to automatically [U][B]mbt shoes cheap[/U][/B] exercise. As a result, muscles are strengthened and toned and posture is improved. Also, we experience less joint stress and back [U]mbt sneakers[/U] pain. Clearly, it's quite a workout, and the benefits are vast.
Many top athletes credit MBT shoes for enhancing their [U][B]mbt sneakers[/U][/B] training routines. Celebrities are also singing MBT's praises [B]mbt shoes cheap[/B] for their alleged ability to tone, reduce cellulite and assist in weight loss. Naturally, this has caused the shoes to [U][B]mbt shoes clearance[/U][/B] get quite a bit of attention.
MBT's simple-yet-effective rolling [U][B]MBT[/U][/B] action with each step is the strategy behind their [B]mbt shoes sale[/B] brilliance. Not long after you begin wearing these shoes and utilizing the rolling technique, you notice [B]mbt shoes cheap[/B] a difference. Your knees and back feel better. Neck [B]mbt sneakers[/B] and shoulder tension begin to melt away. Your joints are less stressed. Your thighs and [U][B]MBT[/U][/B] buttocks appear more toned. Perhaps you [U][B]mbt shoes clearance[/U][/B] even notice a difference in your waistline. Yes, it's the shoes. When you [U][B]mbt shoes best prices[/U][/B] wear them, you actually burn more calories when simply standing than you do when [B]mbt discount shoes[/B] wearing standard shoes. Scientific research proves it.
Now you see why keeping a natural balance is crucial toward maintaining [B]mbt sneakers[/B] a healthier you. If you're making your health a priority, then doesn't it make [U][B]mbt discount shoes[/U][/B] sense to choose footwear that not only increases your fitness level, but also [B]footwear etc[/B] supports improved overall health? Now that you understand what all the [U][B]MBT[/U][/B] hype is about, perhaps it's time to try the MBT experience. Your body will thank [B]mbt shoes clearance[/B] you.

Hi Monu,
I have been using 4GL for the past 15 years. When JAVA and web-based languages were getting popular, I got the opportunities to get involved in several application development projects. However, to-date, none of the web application languages (despite the popular concept of Object Oriented) is comparable to 4GL I used in older day in terms of productivity, maintainability and time to market. Imagine if the customer getting use to one day effort for an enhancement, now require 3 days for the similar task?
Therefore, I understand and appreciate IBM's effort on EGL development. I foresee there are many challenges faced to ensure EGL is able to maintain 4GL's feature - fast development while still retain the web and modern capabilities. As a result, EGL will be more productive than JAVA, but still less productive than traditional 4GL (trade-off with web and modern features).
I personally feel that EGL will not replace JAVA or other languages in certain nature of applications. EGL will be more suitable in developing legacy system, which is traditionally written in COBOL, RPG, Informix 4GL etc.
