What is true about using the Repository pattern?

What is true about using the Repository pattern?

the repository pattern is used to create an abstraction between your domain and data layer. that is, when you use the repository you should not have to have any knowledge about the underlying data source or the data layer (i.e. entity framework, nhibernate or similar).

Is DbContext a repository?

And, to answer your question title: Yes. DbContext is already acting as a repository.

What is generic repository?

It is a data access pattern that prompts a more loosely coupled approach to data access. We create a generic repository, which queries the data source for the data, maps the data from the data source to a business entity, and persists changes in the business entity to the data source.

Why returning IQueryable from a repository is an anti pattern?

By returning IQueryable you do not get back a business entity but you get back a query builder which specifies how to get the data back. Repository should be about what to get and not how to get it. This is the job of the repository, persistence layer of how to get it.

What does work unit mean?

the amount of work done by a unit force acting through a unit distance, or the amount required to lift a unit weight through a unit distance against gravitation. …

What is unit of acceleration?

Unit of acceleration is the metre per second per second (m/s2). Definition. The snewton is that force which, when acting on a mass of one kilogramme, produces an acceleration of one metre per second per second.

What is SI unit of velocity?

Speed and velocity are both measured using the same units. The SI unit of distance and displacement is the meter. The SI unit of time is the second. The SI unit of speed and velocity is the ratio of two — the meter per second . Most people on this planet measure speeds in kilometer per hour (km/h or kph).

What is the SI unit of retardation?

The SI unit of retardation is the same as that of acceleration, that is metre per second squared (m/s2).

What is the SI unit of time?

The second, symbol s, is the SI unit of time. It is defined by taking the fixed numerical value of the cesium frequency ΔνCs, the unperturbed ground-state hyperfine transition frequency of the cesium 133 atom, to be 9 192 631 770 when expressed in the unit Hz, which is equal to s-1.

Which is the smallest unit in physics?

fermi

Is there anything smaller than Planck length?

Originally Answered: Is there anything smaller than a Planck length? There is no even theoretically possible measuring device that can measure differences between two locations that are closer together than a Planck length. Thus, the Planck length is the smallest possible unit of measurement.

Which is the smallest unit of area?

Square Millimeter

What is the smallest unit of weight?

ounce

How do you calculate total area?

Multiply the length of the base, b, by the height, h, to find the total area. The equation for the area, A, of a square or rectangle area can be written as: A = b * h. In our example, the base, b, is 12 inches, and the height, h, is 5 inches. Therefore, the area is 12 inches multiplied by 5 inches, or 60 square inches.

How do you calculate area?

For a square or rectangular room, you will first need to measure the length and then the width of the room. Then multiply the length and width. Length x Width = Area. So, if your room measures 11 feet wide x 15 feet long, your total area will be 165 square feet.
