   • Aggregation of aggregation in Kibana visualization

     Answered Aug 20, 2018 · 2 votes

     as pointed out in the comments already, this requires the bucket_script aggregation in Elasticsearch. This is currently not available for "classical charts" in Kibana (see kibana/#4707).

     You can either solve this using Timelion with the expression (as pointed out by Andrei above) and switch your interval to 1M in the interval chooser in the Editor (or the Timelion App):

     .es(index=test,metric=sum:A,timefield=month).divide(.es(index=test,metric=sum:B,timefield=month))

     Another solution would be to use the "Visual Builder" for which the configuration would look as follows:

     You should also select interval size of 1M under the "Panel Options" in case you want monthly values.

   • Aggregation in MongoDB using Python

     MongoDB is free, open-source,cross-platform and document-oriented database management system(dbms). It is a NoSQL type of database. It store the data in BSON format on hard disk. BSON is binary form for representing simple data structure, associative array and various data types in MongoDB. NoSQL is most recently used database which provide mechanism for storage and retrieval of data. Instead of using tables and rows as in relational databases, mongodb architecture is made up of collections and documents. 

     Aggregation in MongoDB

     Aggregation operation groups the values from multiple documents(rows in case of SQL) together to perform a variety of operations on the grouped data and is going to return a single result for each grouped data after aggregation. 

     Syntax:

     db.collection_name.aggregate(aggregate operations)

     Sample Database used in all the below examples:

     Example 1:

     Python3

     from pymongo import MongoClient my_client = MongoClient('localhost', 27017)db = my_client["GFG"]coll = db["Student"] # Aggregationcursor = coll.aggregate([{"$group":       {"_id":"$Branch",       "similar_branches":{"$sum":1}       }       }]) for document in cursor:       print(document)-

     Output:

     <img>

     Here, we use “$group” command for grouping then by “_id”:”branches” we are grouping ids according to the branches. “similar_branches” is the keyword used...

   • Aggregation in MongoDB

     MongoDB aggregation operations process the data records/documents and return computed results. It collects values from various documents, groups them, and then performs different types of operations on that grouped data like sum , average , minimum , maximum , etc to return a computed result. It is similar to the aggregate function of SQL .

     Aggregation in MongoDB allows users to transform, filter, and analyze data. They are used on multiple documents and provide an efficient way to summarize the data.

     MongoDB provides three ways to perform aggregation

     • Aggregation Pipelines
     • Map Reduce Function
     • Single Purpose Aggregation

     Aggregation Pipelines

     Aggregation pipelines in MongoDB consist of stages and each stage transforms the document. It is a multi-stage pipeline and in each state, the documents are taken as input to produce the resultant set of documents.

     In the next stage (ID available) the resultant documents are taken as input to produce output, this process continues till...

   • Aggregation in SAP UI5

     Top Answer

     Answered Jul 25, 2019 · 2 votes

     Basic definition of «aggregation» from Glossary:

     An aggregation (in the context of UI5) is a special relation between two UI element types. It is used to define the parent-child relationship [...]. The parent end of the aggregation has cardinality 0..1, while the child end may have 0..1 or 0..*.

     For example, a list may have 0 or many items. An item has 0 or 1 list as its parent. Therefore, the list has an aggregation of «items».

     In our case, the control sap.m.App, which is extended from sap.m.NavContainer

     , has a default aggregation named «pages» where we can define a collection of anything extended from sap.ui.core.Control as its child controls.

     pages: sap.ui.core.Control [ ]

     But just adding the views manually into <pages></pages> is an anti-pattern since a view has usually a Page in it and a single page takes up 100% of the height which pushes other views away. Besides that, it makes implementing navigation much more difficult.

     Instead, the current best practice is to use a so-called «router» which is usually defined in the application descriptor (manifest.json) with other navigation properties. Its sister control Target takes care of adding the navigated view to the «pages» aggregation. To find out how to achieve navigation using a router, take a look at these resources:

     • Examples: Basic navigation, navigation inside a static parent control
     • «Routing and Navigation» from Walkthrough (see also further steps)
     • «Routing and Navigation» from Essentials to understand the basic concepts.

   • Aggregation in Data Mining

     Aggregation in data mining is the process of finding, collecting, and presenting the data in a summarized format to perform statistical analysis of business schemes or analysis of human patterns. When numerous data is collected from various datasets, it’s crucial to gather accurate data to provide significant results. Data aggregation can help in taking prudent decisions in marketing, finance, pricing the product, etc. Aggregated data groups are replaced using statistical summaries. Aggregated data being present in the data warehouse can help one solve rational problems which in turn can reduce the time strain in solving queries from data sets.

     This article will explain the aggregation in data mining, their process, and its applications.

     How does Data aggregation work:

     Data Aggregation is a need when a dataset as a whole is useless information and cannot be used for analysis. So, the datasets are summarized into useful aggregates to acquire desirable results and also to enhance the user experience or the application itself. They provide aggregate measurements such as sum, count and average. Summarized data helps in the demographic study of customers, their behavior patterns. Aggregated data help in...
