Column database vs OLAP

We aggregate and tag open source projects. We have collections of more than one million projects. Check out the projects section.

OLAP (Online Analytical Processing), Reporting, Data mining related tasks are usually done by Business intelligence products. They do powerful Extraction, Transformation and Loading (ETL) the data and provides various reports. They use relational database as its back end. How could they generate better reports? Will column DB do a better job?

Business Intelligence and data mining products are available over the years. They are proven and use different techniques to solve the problem. Basically they aggregate data and store in such a way that they could able to perform multi dimensional (MDX) queries. The only drawback is they aggregate the data and it requires more disk space and processing power. To get scheduled reports, the aggregation task should be carried out at scheduled interval (frequent interval). They have good GUI where drag and drop fields will produce good charts.

Column database stores every single column separately. This helps to do better analytics without doing aggregation. It is capable to produce real time reports. Column database is more flexible and dynamic. Developers need to write some code to give better visualization reports where as in case of any BI tools this would be automatic. Not much programing skills or SQL knowledge required.

The best solution would be combining both the ends. An OLAP sever with column database as back end will give benefits of both the worlds.

An Introduction to the UnQLite Embedded NoSQL Database Engine

UnQLite is an embedded NoSQL database engine. It's a standard Key/Value store similar to the more popular Berkeley DB and a document-store database similar to MongoDB with a built-in scripting language called Jx9 that looks like Javascript. Unlike most other NoSQL databases, UnQLite does not have a separate server process. UnQLite reads and writes directly to ordinary disk files. A complete database with multiple collections is contained in a single disk file. The database file format is cross-platform, you can freely copy a database between 32-bit and 64-bit systems or between big-endian and little-endian architectures.

Advantages and Disadvantages of using Hibernate like ORM libraries

Traditionally Programmers used ODBC, JDBC, ADO etc to access database. Developers need to write SQL queries, process the result set and convert the data in the form of objects (Data model). I think most programmers would typically write a function to convert the object to query and result set to object. To overcome these difficulties, ORM provides a mechanism to directly use objects and interact with the database.
