The Solution to the given question can be defined as follows:
Explanation:
Please find the complete question in the attachment file.
In this case, the compiler will try to correct the model type by both the form we used when we try and call the method with both the appropriate form variable. It type of function. Consequently, unless the function in another file is specified, the compiler cannot locate the digital strategy. The point to note here is that only when this code is used, the template code shall be compiled.
The construct component will therefore be efficient so in this case, its connection stage would fail. An undefined connection to the feature <function name> can constitute a possible error in this case. It rules, therefore, address the construction project problem. Furthermore, the template function throughout the main program is generally recommended. It can be solved alternatively because parameters of a template like <function name><type> could be specified throughout the CPP file.

Check the explanation
Explanation:
Step 1: identify the entitles
From the statement given, the given entitles are artists, albums, tracks and played.
Step 2: identify the relationships
- One artist can make many albums
- One album can contain many tracks
- One track can be played many times.
Conversely, each play is associated with one track, a track is on one album, and an album is by one artist.
Step 3: identify the key attributes
The only strong entity in the database would be the “artist”, which has an attribute of artist ID so as to uniquely identifies it
Each album entity is uniquely identified by its album combined with the artist ID of the corresponding artist entity.
A track entity is similarly uniquely identified by its track ID combined with the related album ID and artist ID attributes.
The played entity is uniquely identified by a combination of its played time, and the related track ID attributes.
Step 4: identify other relevant attributes:
The attributes are straight forward; artist, albums, and track have names as well as identifiers to uniquely identify each entity. The track entity has a time attribute to solve the duration and the played entity has a timestamp to store when the track was played.
