Columns Panel
Using columns panel you can specify the columns which you want to be displayed in your query results.
You have a list of lines, each of them represents a column in the query results (in the Results Panel). Every line consists of Expression, which is an attribute, a Title, which serves as a column title in the Results Panel, and buttons – for sorting (on the left), aggregating and deleting (on the right).
Conditions Panel
Here you can specify filtering conditions for data selection. So the result of your query will include only the data that satisfy those conditions.
Every line in the Conditions Panel corresponds to a single query condition. Every condition consists of 3 elements – an expression (some entity attribute), an operator, and value(s) (one or more).
We have mentioned attributes above (e.g., ‘Company Name,’ ‘Product Price,’ and ‘Order Date’). Together with values, operators set certain limitations regarding data which is stored under a given attribute. For example, “(Date) is equal to 23 Jul 2014,” “(Quantity) is greater than 35,” “(Price) is less than 1,000,” and “(Name) starts with A.”
Basic queries: hot to make them with
Advanced Search
1) Display Table Data
Let us imagine that we need a table, which contains following data: names of our customer companies along with countries of their origin, names of categories in which they ordered products, and a total sum of orders each of them made.
So, we select following entities and their attributes to add them in the Columns Panel:
- Customer -> Company Name
- Customer -> Country
- Product -> Category
- Order -> Total Sum
Clicking on the Execute button displays our query result just as we need it.
2) Table Data with Aggregated Columns
Advanced Search allows to aggregate data for each column in the query result. For example, we may need a total quantity (amount) of the orders for every company.
We are going to add the following columns:
- Customer -> Company Name
- Customer -> Country
- Order -> Order ID (we need an attribute of the Order entity to calculate the amount of orders)
- Click on the button and select the "Count" function
- Change the title for last column to "Order Count" - just to represent its purpose.
We get the following result:
3) Table Data with Sorting
Let us use the previous example, in which, as a result, we get columns with data on:
- names of customer companies,
- countries of their origin,
- amount of products they paid for.
First steps are the same as in the previous example:
- Customer -> Company Name
- Customer -> Country
- Order -> Order ID
- We make the last line active and select Count after clicking on the Function button
This time, let us sort data by the number of orders, in the descending order. To do this, we
- make the line Count of Order ID active, click on the sorting icon and select Descending
Results are displayed according to the number of orders made by every company, in the descending order.
4) Filtering Data 1 (One Condition)
We often deal with situations when, for example, of all the customer companies, we must select only those which have purchased goods worth 450 or more. In cases like this we should use the Conditions Panel for data sorting.
Let us do a sample query with the following data displayed: customer companies, countries of their origin, and total sum of their purchases. So, in the Columns Panel we select:
- Customer -> Country,
- Customer -> Name,
- Order -> Total sum.
Now we switch to the Conditions Panel and:
- add Order -> Total sum,
- change the operator 'is equal to' to 'is greater than or equal to,'
- and enter 450 in the value slot, as it is shown in the picture below.
:
5) Filtering Data 2 (Several Conditions)
Often we have not one, but several conditions for filtering data. For example, we need a list containing information on:
- customer companies from Germany,
- whose purchases are worth more than 450,
- and those purchased products are in the 'Dairy products' category.
Firstly, we need to specify that, if (by default) every new condition is an additional limitation to the existing ones, they are connected by a conjunction 'and.' In this particular case, it absolutely suits us, but we will show you how to change this (when necessary) a little bit later.
Thus, when building a query, we indicate first which columns to display, through the Columns Panel:
- Customer -> Company name,
- Customer -> Country,
- Order -> Total sum,
- Product -> Category,
then we add the following to the Conditions Panel:
- Order Total sum -> "is greater than" -> 450
- and: Product Category -> "is equal to" -> Dairy products
- and: Customer Country -> "is equal to" -> Germany
See how it looks below:
6) Filtering Data 3 (Several Conditions with AND and OR Conjunctions)
Let us suppose that the query conditions in the example 5) have changed to the following:
We need a list of customer companies which:
- purchased a total of $450 worth of products
- in the Diary category,
- and their postal code contains 4 or 5.
In the Columns Panel, we select:
- Customer -> Company name,
- Order -> OrderID (f = Count),
- Product -> Name
- We keep 'all' in the Conditions Panel's topmost line ("Select records where all of the following apply")
- Using a [+] button, we add a condition: Order -> Total sum -> "is greater than" -> 450
- and another condition: (and) Product -> Category -> "is equal to" -> Dairy Products
- Next to the first line at the top, we add a group of conditions with the help of a symbol {+} and leave 'any' in a newly formed line.
Consistently, after "and any of the following apply," we add two conditions, by clicking a [+] button:
- Customer -> Postal code -> "is equal to" -> 4
- (or) Customer -> Postal code -> "is equal to" -> 5
It will look this way:
7) Enabling/Disabling of Conditions
Let us assume that we are interested in a particular product - Aniseed Syrup. All we need to know is the list of companies that either have paid for their order, or have made an order starting from the first day of the year.
Therefore, we indicate the following in the Columns Panel:
- Customer -> Company name,
- Order -> Freight (f = Sum),
- Product Name (we will use it only to illustrate the example better).
In the Conditions Panel, we will take a set of steps:
- Product -> Product -> "is equal to" Aniseed Syrup
- We create a group of conditions by clicking {+} and using 'any' in "and any of the following apply"
- Order -> Paid -> "is true"
- (or) Order -> Date -> "after (special)" -> First day of the year
Below is the visual representation of our steps:
And the result we get:
It can happen so that we will be needing only total sums of orders made after beginning of the year, or right the opposite - only orders which have been paid for (with no time restrictions).
There is an option of hiding particular conditions specifically for cases like this one. To the right of a condition itself, you will see a 'hide condition' button - [o]. By clicking on it, we get a broader range of data we want displayed:
The result is slightly different from the previous one:
Advanced Search:
What’s That?
It is always good when there are just a few search parameters, and when one can perform a query with a single text line (for example, Full Text Search). Nevertheless, in most cases, you need to conduct search while operating several parameters at the same time. For example, “Find all male files that has blue trousers, an Omega watch and the appendix removed.” In order to specify the conditions of such a query, you will need more than just one text line.
In such cases, Advanced Search would be much of a help. It is a universal query builder UI for data search and filtering. It will allow you setting the search conditions of almost any difficulty, while using exclusively natural language, terms and expressions of which are familiar to user.
Advanced Search Components
The Advanced Search user interface consists of three main components – an File Attributes Panel, Search Conditions Panel, and Result Columns Panel. The picture below can help you understand which is what:
shows the general layout, but the panels can be resized by dragging the horizontal and vertical separators:
File Attributes
While working with Advanced Search, you operate file attributes. They constitute something like the field structure of a DVI file that one can extract through construction of queries.
File Attributes Panel
This panel can be used as a visual representation of all attributes/fields of a DVI file, which we can use to build queries. It can be used to add entity attributes to a Columns Panel (and they will be displayed in the result) or to a Conditions Panel (in order to actually set the query conditions). You can either move selected attributes to the corresponding panels with a mouse or use buttons Add column and Add condition ( 
).
Main branches
- The File branch contains general, administrative attributes of a File
- The AM branch contains all fields that are special to an AM/MP file
- The PM branch contains all fields that are special to a PM/UB or PUI file
- The Common branch contains all fields that exists in all file kinds
In general, it is a very bad idea to select checkboxes at a high level, as it will automatically also select all attributes within the underlying branches, effectively leading to a system overload. Instead, the checkboxes at a high level can be used to ensure that everything within the underlying branches is unchecked when the higher-level checkbox is unchecked.
The buttons are used as:
 | Select all attributes (never use this - will be removed) |
 | Remove selection from all attributes |
 | Add selected attributes to the Result Columns panel to include them in the search result |
 | Add selected attributes to the Search Conditions panel to be able to specify |
Result Columns
Using columns panel you can specify the columns which you want to be displayed in your query results.
You have a list of lines, each of them represents a column in the query results. Every line consists the Attribute name (i.e. Day), a Title (i.e. DOB Day), which serves as a column title in the Results Panel, and buttons – for ordering, deleting and aggregating columns (on the left) and sorting (on the right).
Managing columns
When you click the button in front of each column specification, you get the option to move/delete the column or change its type from simple to grouped aggregate. The aggregation is currently not working.
Sorting the result
When you click the None link at the end of each column specification, you get to option to sort this column Ascending or Descending. If you sort on multiple columns, the first sorted column from top to bottom (left to right on the paper) will have highest priority and so on.
Adding an extra column
Columns can be added from the File Attribute panel or from the Add New Column button.
You have to option to enter a search word, and then only attributes regarding this keyword will be visible in the branches.
Search Conditions
Here you can specify filtering conditions for data selection. So the result of your query will include only the data that satisfy those conditions.
Every line in the Conditions Panel corresponds to a single query condition. Every condition consists of 3 elements – an expression (some file attribute), an operator, and value(s) (one or more).
Attributes, together with operators and values set certain limitations regarding data which is stored under a given attribute. For example, “(Date) is equal to 23 Jul 2014,” “(Quantity) is greater than 35,” “(Weight) is less than 100,” and “(Name) starts with A.”
Enable or Disable Conditions
The checkbox in front of each line allows you to easily enable (checked) or disable (unchecked) any of your conditions so that you don't need to delete a condition in order to temporarily see which records it excludes.
