What is Hyperion?
Hyperion is a database that allows you to access the data very quickly. The company was bought by Oracle in 2007 and Oracle has continued to improve the product.The Fancy name of Hyperion is Business Intelligence and it aims to support better business decision-making.
Thus a BI system can be called a decision support system (DSS). Though the term business intelligence is sometimes used as a synonym for competitive intelligence, because they both support decision making, BI Uses technologies, processes, and application to analyze mostly internal, structured data and business processes while competitive intelligence gathers, analyzes and disseminates information with a topical focus on company competitors.

What are the features of NoSQL?
When compared to relational databases, NoSQL databases are more scalable and provide superior performance, and their data model addresses several issues that the relational model is not designed to address:
Large volumes of structured, semi-structured, and unstructured data
Agile sprints, quick iteration, and frequent code pushes
Object-oriented programming that is easy to use and flexible
Efficient, scale-out architecture instead of expensive, monolithic architecture

For which projects did use NoSQL databases and for what kind of problems?
It is hardly possible to name a project for which a NoSQL database would be useless, except for a blog or a home page. As the main use cases for NoSQL stores I would mention the following tasks:
● collecting and analyzing large volumes of data
● scaling large historical databases
● building interactive applications for which performance and fast response time to users’ actions are crucial
The major “drawback” of NoSQL architecture is the absence of ACID engine that provides a verification of transaction. It means that financial operations or user registration should be better performed by RDBMS like Oracle or MS SQL. However, absence of ACID allows for significant acceleration and decentralization of NoSQL databases which are their major advantages. The bottom line, non-relational databases are much faster in general, and they pay for it with a fraction of their reliability. Is it a good tradeoff? Depends on the task.

Data Warehouse vs Big “Data Lake”. What are the similarities and what are the differences?
Even though Big “Data Lake” is a metaphor, I do not really like it.
This name highlights that it is something limited, isolated from other systems. I would better call this concept a “Big Data Ocean”, because the data added to the system can interact with the surrounding systems. In my opinion, data warehouses are a bit outdated. At the earlier stage, such systems enabled companies to aggregate a lot of data in one central storage and arrange this data. All this was done with the acceptable speed. Now there are a lot of cheap storage solutions, so we can keep enormous volumes of data and process it much faster than with data warehouses.
The possibility to store large volumes of data is a common feature of data warehouses and a Big “Data Lake”. With a flexible architectures and broad capabilities for data analysis and discovery, a Big “Data Lake” provides a wider range of business opportunities. A modern company should adjust to changes very fast. The structure that was good yesterday may become a limitation today.

هوش کسب و کار، عنصر فراموش شده در استراتژی CRM
اگر شما از شرکت هایی هستید که بر روی مدیریت ارتباط با مشتری (CRM) سرمایه گذاری کرده اید، حتماً دارای خدمات، برنامه های کاربردی و اطلاعات یکپارچه ای برای توانمندسازی رفتار مشتری-محور در سازمان هستید .
اگر جزو 65 تا 80 درصد از شرکت هایی هستید که معتقدید سرمایه گذاری شما بر روی CRM انتظارات شما را براورده نساخته است، بخش کلیدی راه حل را از دست داده اید : «یک فرایند هوش کسب و کار»
💥 فرایندی که موجب تغییرات اساسی شود .
پیچیدگی و تعداد تصمیم های کسب و کار به طور روز افزون در حال افزایش است . مشتریان امروزه انتظارات سطح بالاتری از سازمان دارند و در عین حال با چالش های فنی و کاری بیشتری در ارتباط گیری با سازمان شما مواجه می شوند.
در این میان، 🎯 رویکردهای تحلیلی (Analytics) و هوش کسب و کار نقش تعیین کننده ای در استراتژی های جامع سازمان ایفا خواهند کرد.

Does ODI support web services?
Yes, ODI is ‘SOA’ enabled and its web services can be used in 3 ways:
The Oracle Data Integrator Public Web Service, that lets you execute a scenario (a published package) from a web service call
Data Services, which provide a web service over an ODI data store (i.e. a table, view or other data source registered in ODI)
The ODIInvokeWebService tool that you can add to a package to request a response from a web service
