How do differentiate between brand management and trade marketing?

Trade marketing is a discipline of marketing that relates to increasing the demand at wholesaler, retailer, or distributor level rather than at the consumer level.
However, there is a need to continue with Brand Management strategies to sustain the need at the consumer end.
A shopper, who may be the consumer him/herself, is the one who identifies and purchases a product from a retailer.
To ensure that a retailer promotes a company's product against competitors', that company must market its product to the retailers, as well.
Trade marketing might also include offering various tangible/intangible benefits to retailers.
The alignment of sales and marketing discipline to profitability can be another explanation for trade marketing.
Where as, Brand management is a communication function that includes analysis and planning on how that brand is positioned in the market, which target public the brand is targeted at, and maintaining a desired reputation of the brand.
Developing a good relationship with target publics is essential for brand management.
Tangible elements of brand management include the product itself; look, price, the packaging, etc.
The intangible elements are the experience that the consumer takes away from the brand, and also the relationship that they have with that brand.
A brand manager would oversee all of these things.
