I think after some preparation, a beginner will be able to use SAP Data Services, however, if you are completely unprepared, you may have some issues. I think that in particular you will need a more experienced colleague to help you set up the software. This is because this tool has many components which need to be configured - it is mainly for enterprises so that is only natural. If you come as an absolute newbie to this, you can definitely struggle to set it up. However, if you find someone else to do it, operating with it can be easier, especially if you watch some tutorials online. So, in conclusion - setting it up is for experts, but after that, pretty much anyone can use it.
Yes, I would recommend SAP Data Services to complete beginners. If your company has not used such a tool before and is looking for a data store with a database, then this product is very easy to understand and utilize. The level of complexity may increase if you want to perform advanced tasks or connect the tool with other SAP systems. However, you can resort to their support for that, or you can hire an expert. If someone from your IT department installs it and does the technical things, your whole team, whether they are beginners or more experienced, can benefit from good data integration and quality.
I think that SAP Data Services is definitely worth the money. I work at a medium to large sized company and when we were deciding which licensing to get, we opted for the enterprise package. We did that with a future outlook as we hope to grow in the coming years and did not want to change our data quality software every time our data load increased. In retrospect, this was a great decision. The few extra thousand that this package adds are nothing compared to the quality of services it delivers. From my experience, the product-to-price ratio is completely fair and you get your money back through its good work.
I believe the license for the product is fair, even though some competitors offer similar services at lower prices. The difference between the Edge edition and the next one up is significant in price - more than double. That's a bit off-putting if you are a smaller company that wishes to use more features of this tool. However, I feel the cheapest package is still worth the price. I am not sure if my company would be ever big enough for the most expensive edition of this product, thus I do not know what features it offers. But my general impression is that clients from all levels favor this product over its competitors and it is good for its price.
