A data cube enables data to be modeled and viewed in several dimensions. It is represented by dimensions and facts. In other terms, dimensions are the views or entities related to which an organization is required to keep records.For instance, AllElectronics can create a sales data warehouse to maintain records of the store’s sales-related dimensions time, item, branch, and location. These dimensions enable the store to maintain track of things like monthly sales of items and the branches and locations at which the items were sold.Each dimension can have a table related to it. It is known as a dimension ... Read More

The SELECT clause in the materialized view creation statement represents the data that the materialized view is to include. Some restrictions that limit what can be defined and multiple tables can be joined together. There are several elements including views, inline views (subqueries in the FROM clause of a SELECT statement), subqueries, and materialized views that can all be joined or imputed in the SELECT clause.There are the various types of Materialised views are as follows −Materialized Views with Aggregates − In data warehouses, materialized views generally include aggregates. For a quick update to be possible, the SELECT list must ... Read More

EAI Solutions are changing from middleware messaging systems to Business process Integration. The EAI market is concentrated generally on the layers of the OSI model for EAI, viz., Integration middleware, and Interface Syntax. The main reason for the target on these two layers is the immaturity of the EAI industry and also that profits are simpler to produce in these two layers.Platform Integration − This supports connectivity between heterogeneous hardware, operating frameworks, and application platforms. There are several technologies supporting platform integration are −Messaging − this is for asynchronous connectivityRemote Procedure Calls − Synchronous connectivityObject Request Brokers − Both types ...

There are various types of EAI software topology which are as follows −Hub/Star TopologyHub typology helps generate a main point of control. Messages are shared from source to central hub, which is provided in the machine itself. Hub typology works if business events are autonomous and if the Message Oriented Middleware (MOM) on which the typology is based from an individual vendor. Therefore the source application shares an individual message in one format and the hub reformats the message as essential and broadcast it to the multiple radius linked to the hub.Advantages of Hub/Star TopologyIt can be used to decrease ...
