            Storing layered objects in a grid
            Asked 2021-Dec-05 at 03:53

            Let's say I have a canvas where there are various objects I can add in, such as a/an:

            • Drawing
            • Image
            • Chart
            • Note
            • Table

            For each object I need to store the dimensions and the layer order, for example something like this:

            • ObjectID
            • LayerIndex
            • Dimensions ((x1, y1), (x2, y2))

            Each of the objects have vastly different properties and so are stored in different tables (or classes or whatever). Would it be possible to store this into a relational database, and if so, how could it be done? In JSON it would be something like this:

            ...

            ANSWER

            You have many options as shown below.

            There is not much difference in which one you pick, but I would avoid the multi-table design which is the one you said. An object type with 100 properties would be scattered in 101 tables for no gain. 101 disk page accesses for each object type being read. That's unnecessary (if those pages are cached then this problem would be lesser than otherwise but is still waste).

            Even dual table is not really necessary if you don't wish to filter things like 'all objects with color=red', but I guess performance is not so urgent to reach to this point, other things matters more, or other bottlenecks have more influence in performance, so pick the one of the no-more-than-dual-table that fits best for you.

            Single table - flexible schema per object type objlayerindex type props x0 y0 x1 y1 0 drawing {color:#00FF00,background-color:#00FFFF} 1 2 3 4 1 chart {title:2021_sales,values:[[0,0],[3,4]]} 11 22 33 44
            • in props the keys are used for flexibility, different objects of the same type may have different keys, for example a chart without subtitle can omit this key.
            Single table - fixed schema per object type objlayerindex type props x0 y0 x1 y1 0 drawing #00FF00,#00FFFF 1 2 3 4 1 chart 2021_sales,"[[0,0],[3,4]]" 11 22 33 44
            • this schema is fixed - drawing always has color+backgroundcolor; chart always have title+values; etc - less space used but changing schema involves some work on already existing data.
            Dual table Main objlayerindex type x0 y0 x1 y1 0 drawing 1 2 3 4 1 chart 11 22 33 44 Properties objlayerindex propertyname propertyvalue 0 color #00FF00 0 background-color #00FFFF 1 title 2021_sales 1 values [[0,0],[3,4]]
            • here we assume that property ordering is not important. If it is, an extra column propertyindex would be needed. For those who love normalization, it is possible also to take propertyname out of this table to a propertykey-propertydescription and reference it by its propertykey.
            Multi table Main objlayerindex type x0 y0 x1 y1 0 drawing 1 2 3 4 1 chart 11 22 33 44 Color objlayerindex colorcode 0 #00FF00 Background-Color objlayerindex colorcode 0 #00FFFF Title objlayerindex title 1 2021_sales Values objilayerindex chart 1 [[0,0],[3,4]]
            • Specifically this kind of data can be normalized one extra level:
            Values objlayerindex datapoint x y 1 0 0 0 1 1 3 4

            You can also use non-relational formats.

            You can do (almost!) anything with an aggregate query. In your case I suggest using $unwind to convert the lists to onjects, then $match on your target field(s), $project to trim down the output, $replaceRoot to simplify the structure and $limit for good measure as there's actually 2 records that match your criteria.

            How does MongoDB cursor behave when the collection is being changed?
            Asked 2020-Aug-15 at 22:20

            Suppose I'm using the cursor to iterate a subset of the documents, ordered by some field let's say.

            What happens if while iterating, a new document is being inserted or a current one is being deleted?

            Would that affect the cursor or does it MongoDB make some sort of snapshot of the data?

            When you are in a transaction with read concern snapshot, you are reading from a consistent snapshot of the data.

            Otherwise you could be experiencing various phenomena described here.

            How do I store a picture in azure blob storage in asp.net mvc application?
            Asked 2020-Mar-11 at 06:06

            I am currently working on an ASP.Net application that stores student information. I am required to store the following information:

            • Student number
            • Name
            • Email address
            • Home address
            • Contact no.
            • Upload photo of the student
            • isActive flag to state whether the student is active or not

            This information is being stored in a document database and the photo of the student needs to be uploaded to Azure blob storage while returning the link of the image to the document database

            How do I do this?

            I currently have a class for the student information which looks like this :

            Using Azure CosmosDB for the storage could help. With CosmosDB, you can easily store the image as an attachment to the student document: https://docs.microsoft.com/en-us/rest/api/cosmos-db/attachments

            If you don't plan to use CosmosDB, be more precise please about the database storage.

            Mongoose commands analogous to relational database commands
            Asked 2020-Jan-18 at 23:25

            I am very confused between schema, model, instance of a model, and collection in Mongoose.

            My understanding is as follows:

            1. Mongoose.schema( { } ) - analogous to defining the columns of a table in relational databases
            2. Mongoose.model( 'Name', Schema) - analogous to creating a table in relational dbs (create table statement)
            3. new Model ({ //DATA }) - analogous to creating a row in relational dbs
            4. new Model ().query() - analogous to query statements (general Query) in relational dbs

            Is this correct?

            ...

            ANSWER

            Answered 2020-Jan-18 at 19:54

            You are mostly correct.

            Firstly MongoDB is unstructured by nature, hence i recommend not trying to find "analogies" to match it to the structured scheme. With that said similarities do exist so for simplicity we can do so.

            One more note is that this syntax your referring to is mongoose specifically and not the original Mongo syntax.

            1. Mongoose.schema( { } ) Yes, mongoose gives you the ability to "force" a structure, note this will only come into play when trying to insert/create/update documents and not when it comes to querying.

            2. Mongoose.model('Name', Schema) Yes-ish, mongoose will not create a database per-se, meaning if it does not exist a new one will be created, however inserting a document to that model will create a such collection.

            3. new Model ({ //DATA }) Yes, however you need to add new Model().save(), without the save it will not be triggered and saved into the database.

            4. new Model ().query() Yes-ish, again similar to the model function this is a mongoose wrapper (that I'm less familiar with) As specified in the docs:

            Query constructor used for building queries. You do not need to instantiate a Query directly. Instead use Model functions like Model.find().

            Personally I just use the Model functions to query such as find,findOne,aggregate and more.
