Online analytical processing (OLAP)

Online transaction processing (OLTP)

Existing: Olden days we used to implement everything on our own using basic graph/charting tools.

Suggested: Build frame work with basic tools to longevity or go with self service software for quick returns. Architect need to decide based on business needs. In current world we need to keep mobile users in mind while designing solutions. Mobile devices need rich UI and lighter data sizes to CPU power and band width issues.

Database Replication

January 6, 2015 Leave a comment

Database Replication can kill production if right technique was not selected. Identify the purpose/need for database replication. Put a scope around it and identify right technique and tools to achieve the goal. Setting authorization on data is very important. Always treat data with most respect as cash. Visit compliance / audit issues.

Why we need database replication?
1. To re-produce production issues in other environment.
2. To analyze production data
3. To run reports / business intelligence
4. For failover purpose
5. For back up
6. To achieve high availability
7. To improve performance for end user by putting db servers across continents and sync them up.
And many more

Types of Replication

Transactional replication.
Merge replication.
Snapshot replication.
Good pointer from Microsoft: http://msdn.microsoft.com/en-IN/library/ms152531.aspx

Interior Design – Light

December 29, 2014 Leave a comment

While designing Interiors, Light plays vital role. We need to consider Sun rise, Sun set and Sun’s travel path around home. Also we need to know importance of colors and its impact on human psychology. Many people use too many bulbs, too many shades, blinkers and finally make it as club house. This type of settings takes away the peace of mind.
