In the present context, "a" means not only "only one" but also "more than one".

RAM (Random Access Memory) is an internal memory that exchanges data directly with the CPU, also called main memory (memory). It can be read and written at any time and is fast, often acting as a temporary data storage medium for operating systems or other running programs. It is characterized by volatility, that is, power loss and memory loss, and the speed is higher than ROM. It plays an important role in the performance of the mobile phone. In addition, after the power is turned off, the data is cleared. For example, the mobile phone runs QQ and other applications, and after restarting the mobile phone, The application is not logged in.

ROM (Read-Only Memory) is a solid-state semiconductor memory that can only read pre-stored data. Its characteristic is that once the data is stored, it can no longer be changed or deleted. It is usually used without changing the data frequently. In electronic or computer systems, and data is not lost due to information after power failure, access speed is very low, (more than RAM) and can not be rewritten, often used to store a variety of fixed programs and data.

Cache is generally used for RAM memory to store temporary data. The content stored after power off will disappear. The cache is a temporary file swap area. Putting the most commonly used files from the memory and putting them in the cache is like putting the tools and materials on the workbench. This is more convenient than going to the warehouse.

In all of the following embodiments, the first storage area is a RAM, the second storage area is a ROM, and the third storage area is a cache or a database.

In the prior art, all data is pre-stored in the RAM, but all data is stored in the RAM. First, storing the larger data to the RAM increases the waiting time. Second, it will cause all the data to be loaded before it can be displayed. This will cause the terminal's application interface to appear blank for a long time, which will affect the user's experience. Different from the prior art, the present invention obtains the loading command of the first query condition in real time, obtains the first index value according to the first query condition, and obtains the target data according to the first index value for preloading, so that the user can select according to the query request or The use of the target to obtain the target data in a targeted and purposeful manner, so as to preload the target data to the RAM, so that the size of the data loaded into the RAM can be reduced, the burden on the RAM can be reduced, and the load can be improved.

Specifically, in this embodiment, the present invention separately stores and stores different data files according to the second index value by using the server, and then stores the data files in the server's own storage, only the user needs The application file is packaged in the APK package, and the server sends the APK data packet to the terminal, and the terminal decompresses the packaged APK data package. When the user needs to use the application, the first index value is obtained, the corresponding second index value is obtained according to the first index value, and then the corresponding data file is found from the server's storage according to the corresponding second index value. Then, according to the first index value, the target data is searched and acquired from the corresponding data file, and then the server sends the target data together to the terminal through the network in real time, and the terminal receives the target data sent by the server, and then loads the data in the terminal's RAM. Display, because only the target data is obtained, the data processing method of the present invention can improve the loading speed of the Android platform application, and optimize the memory occupancy and the size of the APK file to improve the user experience. In addition, if the target data is too large, even if you use binary encoding and compression technology, still occupy a large space can not meet the requirements, you can put the target data into the server database, use the network loading method to dynamically download data when the application starts. Give a solution. The invention solves the problem of loading memory consumption, the size control of the APK and the time-consuming problem of the first startup of the application, so that the application loads the target data faster when the application starts, and the memory space is occupied less and the APK file is smaller. The invention splits the preloaded data, so that when the application is started for the first time, only the target data needs to be loaded before the display interface, so the application startup speed and the memory usage can be accelerated.

3 is another embodiment of a method for data preloading according to the present invention, including:

S510, the server sends the application file and the data file to the terminal;

S630, the terminal receives the application file and the data file sent by the server;

S240, the terminal installs the application in a second storage area according to the application file, and runs the application script in the first storage area;

S650: The terminal saves the data file to the second storage area according to the second index value;

S950: The terminal, according to the first index value, obtain a corresponding second index value;

S1900: The terminal searches for a corresponding data file from the second storage area according to the corresponding second index value;

S910: The terminal acquires the target data in the corresponding data file according to the first index value;

In S980, the terminal loads and displays the target data in the first storage area, and saves the target data to the third storage area according to the corresponding second index value while loading the display.

Specifically, in this embodiment, the server first needs to classify and classify a large amount of irregular data, and the present invention performs data acquired on the network or data stored by the server itself according to the obtained second query condition. The data written by the manager is classified and stored, and generated in real time. Name the saved data file with the second index value to speed up the search or search. For example, in the Android platform development, it often involves the function of displaying target data. This usually requires preloading a large amount of data into the memory from the application installation package (APK, hereinafter referred to as APK) and using it according to the loaded data. Specific conditions are queried for the required data for display. How to load a large amount of data when the application starts without affecting data display becomes the core problem in the implementation of this function. Currently, a large amount of data preloading on the Android platform usually adopts the following two methods:

1. Preset the SQLite database table file in the APK. When the application starts for the first time, copy the file to the specified database path of the application, so that the database can be directly read for data query and display.

2. The preset data file in the APK, the file can be binary code. When the application is first started, the file is parsed and read into the memory, so that the data can be directly queried and displayed, and the cache file or database can be generated. The supply is used directly at the next startup.

The above two methods are feasible in the case of a small amount of data, but in the case of a large amount of data, there are obvious drawbacks. The database file is used in mode 1. When the amount of data is large, the file must be large. At this time, the APK is inevitably large, affecting the user experience, and it is time-consuming to copy the database file when starting the application. The use of binary files in mode 2 can relatively eliminate redundant data, and solve the problem that the APK is too large, and this method needs to load all the data into the memory when the application is loaded, which occupies a large amount of memory, and defines the virtual machine memory. Smaller devices can easily reach the upper limit and exit with Out Of Memory (OOM), and do not solve the time-consuming problem.

The invention separately stores and stores different data files according to the second index value by the server side, and then packages the data files together with the application files in the APK package, and the server sends the APK data packet to the terminal, and the terminal will package the data. The APK packet is decompressed, and the data file is saved to the second storage area of the terminal, where the second storage area is ROM. When the user needs to use the application, the first index value is obtained, and the corresponding second index value is obtained according to the first index value, and then matched with the second index value generated by the server according to the corresponding second index value, according to the matching. As a result, the corresponding data file is found from the ROM, and the target data is searched and acquired from the corresponding data file according to the first index value. Because only the target data is acquired, the loading of the Android platform application can be improved by the data processing method of the present invention. Speed, and optimize the memory footprint and the size of the APK file, improve User experience.

Preferably, the step S900 further includes the following steps:

S990: The terminal saves the remaining loading data to the third storage area according to the corresponding second index value; the remaining loading data is data in the data file other than the target data.

By pre-storing the remaining loading data into the third storage area, where the third storage area is a cache or a database, the late user can quickly call the remaining loading data to load and display the target data when the user uses the application. The application's loading speed improves the user experience.

In the following, for the sake of easy understanding, for example, the calendar program is required to specify the calendar data between 1900 and 2100 as an example, and the calendar data includes the date and the data information of Yihe. As shown in Figure 4, the steps are included:

S11. Calculate an index value according to the first query condition for all the data;

Here you need to calculate the index value of all the data. For the calendar data, it is obvious that the first query condition is the date. Here, the direct splicing algorithm is used to calculate the index value. For example, on June 24, 2017, the calculated first index value is 20170624 integer type data (if it is other types) Data, you can use the hash algorithm to calculate the hash value as an index value, not to mention here).

S12. Generate a second index value by using the first index value according to the second query condition.

Here, as needed, the first 4 bits of the first index value are taken to generate a second index value, for example, the first index value is 20170624, and the first 4 bits get 2017 as the second index value.

S13. The second index value calculated in S12 is used as a file name of the data file, and the data classification is saved into a plurality of corresponding data files.

In this way, the calendar data of the 200 years between 1900 and 2100 can be divided into 200 data files, and compressed and packaged into APK packets with the application files and sent to the terminal. As shown in Figure 5, the steps are included:

S21. Save all the data files to the ROM according to the corresponding second index value.

Here, the data packet generated in step S13 is decompressed into the application data directory. After receiving the APK data packet, the terminal decompresses the APK data packet, installs the application according to the application file, and saves the data file to the ROM according to the corresponding second index value.

S22. Perform a calculation according to the first query condition and the same algorithm as S11 to obtain a first index value.

Here, for the calendar data, when the calendar program is loaded, the calendar of the current month is displayed and the calendar information of the day is displayed, so at least the data of the day is required, and the first index value is calculated according to the date of the day of June 24, 2017, and the same step S11 is required. Algorithm, get the first index value 20170624.

S23. Obtain a corresponding second index value according to the first index value obtained in S22, and find a corresponding data file according to the second index value, and search for the target data from the corresponding data file according to the first index value;

Here, after calculating the first index value 20170624, the second index value is obtained according to the same algorithm as S12, and the data file with the file name 2017 is found.

S24. Load the S23 in the RAM to search for the acquired target data and display it;

Here, since the total amount of data is only one-twoth of all data, the loading speed and memory usage are small, and the display target data of the application can be completed as soon as possible.

S25. While loading the display, storing the target data to the cache, and storing the remaining data to the cache;

Here, the child thread is created, and the target data loaded by the S24 is asynchronously saved as a cache file in the child thread or stored in the database, and the remaining data of the remaining 199 years is loaded, and saved as a cache file or a cache database for the next application. Used at startup.

Through the data processing method of the present invention, the loading speed of applications such as the Android platform and the IOS application platform can be improved, and the memory usage and the size of the APK file are optimized, and the user experience is improved.

In this way, the target data can be acquired in a targeted and purposeful manner according to the user's query needs or usage requirements, thereby pre-loading the target data to the RAM, so that the data loaded into the RAM can be reduced relative to the prior art. The size of the RAM reduces the load on the RAM and improves the performance of the RAM, so that when the application display interface displays the target data, it can speed up the application startup speed and optimize the RAM.

Referring to FIG. 7, the present invention provides another embodiment of a data preloading system 1000. The other parts of this embodiment are the same as the previous embodiment;
