Safety Measures For Sulfuric Acid Accidents

Posted on by

One day I was given the task to make a report on a certain chemical called H2SO4. I was totally dumbfounded as I had no idea what it is and what I should research about it. In fact, I did not even have an idea how to buy sulfuric acid since I do not use it in my everyday life. Or so I thought.

For starters, I tried to find what this H2SO4 really is. Well, a simple researching in the internet told me that the chemical is commonly known as sulfuric acid. And, as my research grew more intensive, I found out a lot about the acid that made me realize its benefits to some industries.

It is actually used in some industries that help produce some of the basic necessities that we use in our everyday lives. For one, the chemical is used in agriculture to produce fertilizers that can be used in crop production. An example of these fertilizers is phosphate fertilizers. The chemical is also an important ingredient in making detergents and other household cleaning products. It is also used in other industries that make steel, industrial explosives, iron, lead acid batteries and dyes.

OLAP processes vast queries

Posted on by

Online Analytical Processing (OLAP) helps to process vast queries online. Queries are multi dimensional and analytical. It is a part of business intelligence. It includes relational reporting and data mining. OLAP gives service in the area of business reporting for sales, business process management, marketing, management reporting etc. It also includes new areas like agriculture. The term OLAP is derived from another term which is OLTP (Online Transaction Processing).

OLAP contains some databases which use a multidimensional data model. It facilitates complex analytical and vast queries very fast. Some aspects are common to navigational as well as hierarchical databases. These databases are more speedier than relational databases. The result of an OLAP query is generally displayed in the matrix format. It is also called pivot format. Rows and columns of the matrix are made from the dimensions and the values are formed by the measures.

An OLAP cube is there in the core of an OLAP system. It is also called a multidimensional cube or a hypercube. Some numeric facts are there which is called measures. They are classified into the dimensions. We get measures from the records of the fact table and dimensions from the dimensions tables. A set of labels or its meta-data are meant by a measure. These labels are described by a dimension. It contains information about measure. For example a cube contains a store’s sales which is the measure and the date/time which is dimension. Each sale contains date/time label which describes that sale in more detail.
