The process of arranging any items in a systematic manner in a logical sequence is called as Sorting. It can be of two types :

1. Ordering

Arranging items following some criterion like ascending or descending order

2. Categorizing

Grouping items with similar properties together.

An unspecified passive open has the server waiting for a connection request from a client. A fully specified passive

open has the server waiting for a connection from a specific client.

- TABLES
- VIEWS
- INDEXES
- SYNONYMS
- SEQUENCES
- TABLESPACES

Aynchronous and Event Driven - All APIs of Node.js library area unit aynchronous that's non-blocking. It basically means that a Node.js based mostly server not waits for a API to return information. Server moves to next API when calling it and a notification mechanism of Events of Node.js helps server to induce response from the previous API decision.

Very Fast - Node.js library is very fast in execution of code.

Single Threaded but highly Scalable - Node.js uses a single threaded model with event looping. Node.js uses a single threaded program and same program can services much larger number of requests than traditional server like open source.

No Buffering - Node.js applications never buffer any data. These applications simply output the data in faster.

The primary keys of entity tables are the foreign keys of dimension tables.

The Primary keys of fact dimensional table are the foreign keys of fact tablels.

Language Integrated Query (LINQ) adds the ability to query objects using .NET languages. The LINQ to SQL object/relational mapping (O/RM) framework provides the following basic features:

- Tools to create classes (usually called entities) mapped to database tables

- Compatibility with LINQ's standard query operations

- The DataContext class, with features such as entity record monitoring, automatic SQL statement generation, record concurrency detection, and much more

-  The process of having a copy of redo log files is called mirroring.
-  It is done by creating group of log files together. This ensures that LGWR automatically writes them to all the members of the current on-line redo log group.
-  In case a group fails, the database automatically switches over to the next group. It diminishes the performance.

Use the SORTWK01, SORTWK02,..... dd names in the step. Number of sort datasets depends on the volume of data being sorted, but a minimum of 3 is required.
