Here is what some of our highly satisfied customers had to say about our e-books, question books and revision guides…

"Truly amazing! − I recently bought e-books from Knowledge River to help in a database design project I am currently completing. The information they hold is clear, comprehensive and easy to follow, with numerous supporting diagrams and scenarios. These books are a "must have" for anyone serious about designing relational databases – absolutely A1!!"

Martyn J Cox − Quarry Bank, West Midlands, United Kingdom
(BSc Computing Graduate)

"I have been using the revision guide and it has been a great help. I am actually enjoying studying using it − I know it's very strange. It has given me a good idea of the areas that need more work… It was excellent. I cannot say that there were any bad bits in it. Did it actually help me prepare for the exam? Definitely. I didn't use anything else and feel that I did okay… absolutely worth every penny."

Fran G. − Elgin, Moray, Scotland
(BSc Computing undergraduate)

"…I really liked what was offered and so that is how I found your site (by accident); but glad I did… To be honest sites like yours offer much better learning sources and more reasonable prices than here. Again, thanks for your assistance so I could complete my order & thanks for your great customer service."

Dave R. − Colorado, America
(IT Professional)

"Was it any good? Most definitely! It was good for checking the knowledge and getting a quick walk through. The biggest help was for the theoretical questions and concepts."

Jozef S. − The Netherlands
(BSc Computing undergraduate)

"Knowledge River books have already proven to be a great investment even though I have only owned them for a month. The style is easy to read and very user friendly. I have already dipped into material when designing a database and used their examples to help clarify a real problem I had. The further examples and question banks are great − real examples of what to do giving plenty of practice so that it becomes second nature. For once, dry technical material is made interesting − the author leads you through it as though a friend is explaining how it all fits together – relational databases de-mystified! Don’t be misled that I think these are simple − the standard is high and they lead you from frightened novice to confident with solid technical knowledge in a few hundred pages! At last I have found books that I have used instead of leaving on the shelf for future reading. A real ‘must’ for beginners and advanced users alike. Excellent value for money."

Diane Parsons FCMA − Dudley, West Midlands, United Kingdom
(Director, IYH Business Consultancy Ltd)

"Your revision guide was excellent – well worth the £20 – I just wish I could have had it much earlier, I could have used it more as a study guide than a revision guide. I thought the explanations were very clear – for example in Q46, the step by step explanation of the solution was very useful, rather than just having the answer."

Christina N. − Edinburgh, Scotland
(BSc Computing undergraduate)

"Your guide was very useful and I especially appreciated the opportunity to practice all the SQL… it was very well laid out and good for putting the ‘rambling’ sort of question in a nutshell − eg ‘describe the main features of a trigger’. I was happy to pay £20 because, in terms of what the course cost me overall, it was more than reasonable, and a lot of work had obviously gone into the guide… the work you put into it was very much appreciated − and best of luck with it in the future!"

Carol H. − Guernsey, Channel Islands, United Kingdom
(BSc Computing undergraduate)

"The guide has been a real eye opener. It has highlighted many areas that had been forgotten, and has ensured that I delve into the course blocks more thoroughly when revising."

Mike W. − Norwich, UK
(BSc Computing undergraduate)

"The e-books are very professional in their presentation with clear explanations, supported by excellent diagrams and many, many detailed examples… the idea of having a modular design and splitting each topic down into three parts is very good… I read the main e-books first − to get the main concepts – then used the question banks and further examples books to reinforce this… I would be happy to recommend them."

Rebecca H. – Staffordshire, United Kingdom
(ICT student)

"I found the exam pretty hard, as you predicted it would be, and I was glad to have your question book on hand to help me with the revision. With it I was able to revise a topic, then test myself to see how much I could remember! I found it very valuable; and one thing that sticks out in my mind as being really great was the practise it gave with turning ERD shards into Relational models. I felt that really helped me to get my head round subtleties with (e.g.) alternate keys, and what they actually mean to the data model (thus simplifying the translation process); which is something I didn’t feel I really grasped from the course material. I honestly can’t think of any bad things to say about it! All things considered, therefore, I would say that £20 is definitely a fair price! And thanks again for offering the additional materials − they really have been helpful."

Adam J. − West Midlands, United Kingdom
(BSc Computing undergraduate)

"What I like about the Knowledge River books was the fact they gave a slightly different approach… The question and answer approach was, I felt, a good one… So, I think on the whole I have found them useful and believe they are a sound learning product."

David T. − Wolverhampton, United Kingdom
(BSc Computing undergraduate)

"It was perfect for my requirements. All good… I found the publication to be excellent all in all."

Chris M. − London, United Kingdom
(BSc Computing undergraduate)

"I'm finding the eBooks to be a very useful supplement… extra insight in some places, and are presented clearly and concisely (making them easy to read and digest). The presentation of the material is also very appealing… I very much like the way in which each section asks a question, then proceeds to answer it with explanation and examples…"

Adam J. − Oldbury, West Midlands, United Kingdom
(BSc Computing undergraduate)

"Traditional textbooks are alright but they tend to be very expensive while these e-books are very good value − especially if you take advantage of the large discounts available. The fact that you can have multiple copies of each e-book on different computers just makes them even better value! You really get instant e-books, instant knowledge & instant learning − but at a sensible price"

Ernest B. − Bolton, Lancashire, United Kingdom
(Database User)

"Well done Knowledge River! The concept of having a ‘stream’ of database knowledge straight to my desktop is brilliant… the best thing is that I can have copies of these e-books at home and carry them about on my laptop as well so I can study anywhere and the three-way split for each topic is a good idea as it makes learning a lot easier when you don’t have much time… they are good quality, good value for money and really do the job… anyone wanting to know about databases should get these…"

Annabel H. − Tamworth, West Midlands, United Kingdom
(ICT student)

"Yes, it was very good, and helped to reveal which areas I really needed to revise. I used it quite a bit in preparing for the exam – almost more that I used the course books."

Simon K. − Canterbury, United Kingdom
(BSc Computing undergraduate)

"Was it any good? Yes, I used it a good refresher of the entire course. This pointed me to areas where I needed to revisit units "in depth". I only skimmed XML so this was a pretty good alternative, picking up the main points and some were in the exam too… covered the course thoroughly. Did it actually help you prepare for the exam? Definitely."

Keith W. − Doncaster, United Kingdom
(BSc Computing undergraduate)

"Why would anyone want to travel all the way down to a normal bookshop, wasting time and effort − just to pay a small fortune for heavy, bulky textbooks when instead they could come to the Knowledge River website and instantly download these excellent e-books at their own convenience − and at a fraction of the cost. It is an easy decision."

Julie B. − Staffordshire, United Kingdom
(Database & IT user)

"Was it any good? The answer is yes. You got in there first and so I say thanks right now! Did I use it to prepare for the exam? 100% yes !!!"

Adam W. − Wiltshire, United Kingdom
(BSc Computing undergraduate)

"…very useful… The guide was a good method of condensing the information to relevant issues."

Jeff N. − Dalton-in-Furness, Cumbria, United Kingdom
(BSc Computing undergraduate)

"Yes the exam revision guide was useful, it picks out the important points short and concisely, so when you see a question you know what area you should be targeting your answer at."

Samantha M. – Walsall, West Midlands, United Kingdom
(BSc Computing undergraduate)

"As regards the revision guide I do think it's quite useful, the cost is reasonable… it's money well spent."

Philip B. – Newcastle, Staffs, United Kingdom
(BSc Computing undergraduate)

"Finally got around to using this revision guide… the questions in it are very useful, to the point, and I'm utterly horrified at the amount I don't know. It's scary. I'm very glad I've got it… Well I've been using this guide now for a few days, and now I wish I'd started sooner, OMG is this USEFUL. Thank you SO much…it was a bargain. Thank you for all the solutions, they're a potted revision aid…"

Hazel M. − Chelmsford, Essex, United Kingdom
(BSc Computing undergraduate)

"…having also bought the revision guide I must also vouch for its usefulness as a revision aid. It has certainly opened my eyes to a lot of areas where I need to sharpen up my ideas…"

Bernard M. − Glasgow, Scotland
(BSc Computing undergraduate)

"Was it any good? Yes, particularly given that we had no past papers to practice on. Did it actually help prepare for the exam? Yes. I'll just add that I'm glad I bought it."

John W. – Coventry, United Kingdom
(BSc Computing undergraduate)

"I found it very helpful. It enabled me to focus my revision. I attempted the questions, if I had problems answering the questions I went back to the text books and re-read that section. My revision strategy was non existent before this. I also found it a good confidence builder (I felt ready for the exam after answering the questions). Found the whole thing good/positive. Did it actually help me prepare for the exam? Yes, due to the lack of past papers I found it very good. As previously stated, I built my revision strategy around your guide. I was happy to pay £20. I was pleased with the revision pack. I wish I had bought all the e-books at the beginning of the course."

Gary E. − Walsall, West Midlands, United Kingdom
(BSc Computing undergraduate)

"Feedback for the Database revision guide can only be positive. It was very comprehensive and really pointed out to me the areas that needed a little more preparation as well as giving quite an accurate indication as to how questions may be set in the exam… It took me 3 days to work through the guide, I only wish I had found it earlier as I am sure that I could have got a lot more out of it. As far as price goes… yes definitely it was money well spent… To be honest, I reckon that I could easily put at least 30% of what I scored in the exam, down to the study guide."

Brian F. − United Kingdom
(BSc Computing undergraduate)

"I found the revision guide invaluable… Because the revision guide was compacted/consolidated into the key areas it was perfect preparation for me. Thanks… I'm sure I'm not the only grateful student."

Derek C. − Weymouth, Dorset, United Kingdom
(BSc Computing undergraduate)

"Firstly thanks… I enjoyed revision more than usual. The guide was very useful especially covering the breadth of the course. Particularly when resorting to Q15 in the exam. Overall I was very happy: £20 = lots of hours saved."

Mike C. − North Shields, United Kingdom
(BSc Computing undergraduate)

"I would most certainly say that the revision guide helped me prepare for the exam. It helped to highlight the areas where I was most lacking, and enabled me to focus on those topics. The question and answer format of the guide was also perfect preparation for the first part of the M359 exam (the 12 "short" questions). Value for money? Yes, when compared to buying past papers from the OUSA, which do not come with model answers. Thanks again."

Andy M. − Leicester, United Kingdom
(BSc Computing undergraduate)

"I bought your database revision guide earlier in the year and attended your weekend tutorials. I just found out my Open University M359 result today, and I'm very pleased to say that I got a distinction. I really feel that the revision guide and the weekend helped me get those extra few marks to make the grade (I got 86% on the exam), so thanks for your help."

John W − Coventry, United Kingdom
(BSc Computing Undergraduate)

"I just wanted to say thank you for all the help and support you have given me over the course of my project work. I have really appreciated your constructive comments and prods in the right direction."

Julie B − Birmingham, United Kingdom
(Open University Database Project student)

"The Knowledge River Database Project Guide was invaluable throughout the project, from the inception of the project and selection of a topic, through to the evaluation of literature and writing up the final report. It is written in an easy to understand 'plain English' style without any of the academic stuffiness and formality that often afflicts University sourced material."

Graham W. − Newtownards, Co Down, Northern Ireland
(Computing Degree project − Open University)

"The Knowledge River Guides proved to be invaluable throughout the whole process of creating and completing my database project. The Database Project Guide did exactly that − guided me through the whole process from selecting my project right through to writing up the final report while the pack of eBooks was immensely useful in revising as well as fully explaining the processes involved in creating the database. Purchasing the guides was the best investment I made towards completing my degree."

Lorna S. − Littlehampton, West Sussex, UK
(Computing Degree project − Open University)

"I initially purchased only the Knowledge River project guide. This was invaluable in helping me layout the project report and allowed me to review my work against the points discussed. Following this review it was apparent I did not have enough knowledge of the normalization process and at this point I purchased the detailed normalization guide. The detailed guide allowed me to complete this critical part of my project to the required standard. I highly recommend these items to any project student."

"...in my 5 years with the OU your communication has been the very best I have encountered and I very much appreciate it."

Paul S. − Northampton, United Kingdom
(Computing Degree project − Open University)

"I purchased the Database eBooks 1-5 together with their associated further examples and Q&A from Knowledge River and I have to say they have been great. They are written in a way that is easy to follow and understand. They flow together through each stage of the database design process using simple English and clear diagrams. I found that I learnt more from these books than I did from the database course that I studied. The Database Project Guide is excellent if you are studying a Database Project Course as it gives tips on picking your project, what your aims and objectives are and how to discuss the various stages when you are writing your report. So if you are just getting your first taste of databases or you have some knowledge of them I would highly recommend these eBooks. They will certainly make life easier for you."

Karen W. − Barnsley, South Yorkshire, United Kingdom
(Computing Degree project − Open University)

"Thanks for the database project guide. I have purchased it and I am so glad I did, I just wish I had about 4 weeks ago."

Samantha M. − West Midlands, United Kingdom
(Computing Degree project − Open University)

"Hi... Just bought the Database Project Guide. I shall be pouring over it and applying it to my project. Thanks!... and thank you so much for all your support. You're a great tutor!!"

Sonia G. − Keele, Staffordshire, United Kingdom
(Computing Degree project − Open University)

"I have some of these e-books... I think they're good. They (Knowledge River) also did a document to help with exam prep... which definitely helped me out in preparing for the exam."

Lawrence C. − Dublin, Ireland
