Scanning the Manager table, you can quickly see which employees are managed by whom, but you'll have to look qsl each EmployeeID nvinstaller api mr open the Ratabase table to see their information. Scanning the Employee table, you can quickly see information about a particular employee, including the ID of their manager, but you'll have to look up the manager's EmployeeID in the Manager table, and then look that up in the Employee table if you want the name of their manager. This could be drastically simplified by combining the two tables into a single table and avoiding a separate ManagerID by using EmployeeID for both purposes.

There are core basics that every organization needs that leads to a basic standard implementation of a Big Data solution. However, that basic implementation will not provide the best performance for the user in all use cases and situations. There are so many different options now that choosing between all of them can be complicated. Knowing when to use which technology can be tricky. The basic implementation that I have seen is the Lambda Architecture with a batch layer, speed layer and view layer. Hadoop is primarily used as the storage in the batch layer and Cassandra for the view layer. In many cases this architecture will provide the user with the best performance but some analysis should always be done on the overall use case and business needs to determine what Big Data database is best or if a relational database will be best. When examining Big Data solutions that will work for your organization one of the most important theorem to use is the CAP theorem. The CAP theorem explains that there needs to be trade offs between consistency, availability and partition tolerance in a system. Normally it is said that only two can be achieved. However, in truth levels of all three can in fact be achieved but high levels of all three is impossible. When a query is executed against all the nodes of a system simultaneously and the same data will be returned, the system is considered consistent. Availability is achieved when a request to write to the system will always succeed.
